Mold flow analysis mainly examines the flow behavior of plastic melt during the injection molding process and the related parameters. The main contents that mold flow analysis focuses on are as follows:  The flow path of the plastic melt  Mold flow analysis can simulate the flow path of plastic melt in the mold cavity, helping designers understand how the melt fills the mold and whether there are any flow dead zones or uneven flow issues. This is crucial for optimizing mold design and injection molding process parameters. 2. Temperature and pressure distribution at the melt front  Through mold flow analysis, information on the temperature and pressure distribution at the melt front can be obtained. These data are helpful in evaluating the cooling effect of the mold and whether the injection pressure is appropriate, thereby avoiding defects such as warping and deformation in the product. 3. Filling time and injection pressure  Mold flow analysis can predict the filling time and injection pressure during the injection molding process. These data are of great significance for determining the appropriate specifications and process parameters of the injection molding machine, and help to reduce production costs and improve production efficiency. 4. Product defect prediction  Mold flow analysis can also predict potential product defects such as shrinkage cavities, air pockets, and weld marks. By detecting these potential issues in advance, designers can adjust the mold design scheme and injection molding process parameters to reduce or eliminate the defects and improve product quality. 5. Evaluation of Mold Design Scheme  Ultimately, the results of the mold flow analysis are used to evaluate the feasibility of the mold design scheme. By comparing the simulation results of different design schemes, the designer can select the optimal one, thereby ensuring the smooth progress of the injection molding process and the quality of the final product.

PFA (perfluoroalkoxy resin) is a high-performance thermoplastic fluoropolymer that boasts excellent chemical stability, high-temperature resistance, electrical insulation properties, and low friction coefficient. It is widely used in numerous high-end fields such as chemical engineering, electronics, and aerospace. However, during the injection molding process of PFA, due to the material characteristics and complexity of the processing technology, some quality issues often arise. These problems not only affect the appearance of the products but may also have a significant impact on their performance and reliability.  Zhejiang Ceeto Mold Co., Ltd has been overcamed this difficulity and found the good solution to slove injection issues during molding processing.   The shrinkage rate of PFA is relatively high, and its shrinkage characteristics are influenced by various factors. Injection molding process parameters such as melt temperature, holding pressure and time, and cooling speed have a significant impact on the shrinkage rate of PFA products. If the melt temperature is too high, the shrinkage amount of the product after cooling will increase; if the holding pressure is insufficient or the holding time is too short, it cannot effectively compensate for the shrinkage, resulting in a smaller size; if the cooling speed is uneven, the shrinkage of different parts of the product will be inconsistent, causing size deviations. In addition, the design and manufacturing accuracy of the mold are also crucial. Inaccurate mold dimensions or deformation during the injection molding process will directly lead to size deviations of the products.  

The core difficulties in POM injection molding lie in its extremely poor thermal stability (easily decomposes and produces gas/makes color changes), strong crystallization resulting in high shrinkage (2%-3.5%) and difficulty in controlling dimensions, narrow processing window sensitivity to temperature, and high rigidity causing internal stress cracking.  Core difficulties and key control lines ‌Thermal degradation risk‌: Melting point 165-175℃. If held at 200℃ for more than 10 minutes or at 240℃ or above, it will undergo intense decomposition, producing formaldehyde gas, black spots and pungent odors. The processing window for homopolymer POM is only about 10℃, and the co-polymer is slightly wider but still sensitive. ‌High shrinkage and dimensional fluctuation‌: High crystallinity leads to large molding shrinkage rate (1.8%-3.5%), and is greatly affected by mold temperature and holding pressure. It is prone to‌ shrinkage cavities, vacuum bubbles and secondary shrinkage exceeding tolerance after storage‌. ‌Internal stress and cracking‌: The material has high rigidity and limited toughness. Rapid cooling or uneven force during ejection can easily cause‌ top whiteing, stress whitening or even cracking‌, and the strength of the fusion marks is naturally low. ‌Extrusion and exhaust contradiction‌: Good melt flowability easily leads to‌ dripping (dripping material)‌, while a large amount of decomposition gas requires strong exhaust, but a deep exhaust groove is prone to generating flash, making the balance difficult.

The US Congress has introduced a bipartisan bill, the Accelerating Plastics Circular Economy and Recycling Innovation Act of 2024, which aims to drive plastic recycling improvements across the US to increase the use of recycled materials in packaging.       A draft of the bill before its formal introduction says chemical recycling is necessary to meet the U.S. Environmental Protection Agency's national recycling goals and contains regulatory measures favored by the plastics industry, including treating chemical recycling as a manufacturing process rather than a solid waste disposal facility under federal, state or local law. Under the Act, the incineration or burning of plastics is not considered chemical recycling. The bill also proposes to establish a third-party certification system for the quality balance of chemical recycled plastic raw materials       The bill also requires the content of recycled materials in plastic packaging to reach at least 30% by 2030. This standard will significantly boost the recycling rate of plastic packaging in the United States and incentivise the use of packaging designed for recycling, which is currently only about 13%. The bill is expected to more than double that proportion by 2030, laying a solid foundation for even higher levels of recycling in the coming years.       The bill directs the U.S. Environmental Protection Agency to develop national plastic recycling standards, and establishes an advisory committee made up of plastic packaging designers, consumer brands, plastic manufacturers, recyclers, chemical recyclers, and solid waste businesses to increase national recycling rates. Currently, there are more than 9,000 recycling jurisdictions in the United States, with diverse recycling practices and a lack of uniform standards.

In July 2023, the European Commission issued a proposal for a regulation on End-of-Life Vehicles (ELV), which states that new cars should contain at least 25% recycled plastic. In response to the challenge, Shimei Recycling New Materials (Jiangsu) Co., LTD. (hereinafter referred to as "Shimei Recycling") launched 70%PCR automotive interior door trim material solutions to help Chinese cars go to sea.       Europe is the second largest car market in the world, and it is of great significance for China to go to sea to win the European market. The new proposal of ELV, the sea of Chinese cars is about to face challenges. This means that they need to make adjustments in product design, material production, etc., to meet the environmental requirements of the EU.       70%PCR automotive interior door trim material solution   Combined with the market demand, we launched the automotive door panel high-quality recycled plastic solution, using high-quality recycled PP as the substrate, through modification, launched 70%PCR automotive interior door trim material solution.   Through the recycling of recycled sources, the solution reduces the environmental pollution of plastics, reducing carbon emissions by 65%, reducing carbon emissions by 2,952.6 tons/year.   ◆ The new material can not only reduce carbon emission, but also lower the cost than the existing material scheme, saving more than 5% of the cost for customers, the annual cost saving750,000 yuan.   ◆ Materials in the client scale application, to achieve good results. Reducing pollution and carbon emissions also allows customers to reduce the cost of use.

The GRS Global Recycling Standard and the RCS Recycling Declaration Standard are both developed by textile trading organizations and are both focused on recycling certification.       GRS certification   The Global Recycled Standard (GRS) is an international, voluntary, and comprehensive product standard that establishes third-party certification requirements for recycled ingredients, chain of custody, social responsibility and environmental practices, and restricted use conditions of chemicals. GRS certification covers the entire supply chain from raw material collection to final product manufacturing, including textile and apparel, chemical plastics, household goods and many other industry sectors.   The goal of GRS is to increase the use of recycled raw materials in products while reducing or eliminating the harm caused by their production process. The GRS certification applies to any product containing 20% or more recycled ingredients. 50% or more of the recycled ingredients are required to attach the GRS label to the product.       RCS certification   RCS (Recycled Claimed Standard) is an environmental certification standard that ensures traceability and transparency of recycled products and materials. The standard was developed by the Global Recycling Standards Organization (GRS) to promote a circular economy, encouraging companies to adopt sustainable production practices and reduce waste and pollution. Through RCS certification, companies can demonstrate the commitment and efforts of their products in terms of environmental protection and sustainability, thus winning the trust of consumers and recognition of the market.   RCS certification focuses on the content and regulation of recycled materials. Applies to any product containing 5% or more recycled ingredients.       GRS and RCS certification similarities   Both GRS and RCS certifications are developed by textile trading organizations and both focus on recycling certifications. Both certifications are usually valid for one year, during which time the certification body will conduct periodic monitoring and audits to ensure that the enterprise continues to meet the requirements of the certification.   Both GRS and RCS use the ISO 14021 definition of regeneration content and are interpreted based on the US Federal Trade Commission Green Guidelines. The aim is to comply with the most widely accepted and strictest definitions.       The difference between GRS and RCS certification   GRS can be said to be the advanced version of RCS:   ◆RCS products can use GRS certified raw materials, but GRS products can not use RCS raw materials.   ◆GRS applies to products containing 20% or more recycled ingredients, and RCS applies to any product containing 5% or more recycled ingredients.   GRS requires consideration of corporate environmental (such as energy and water use, waste management, etc.) and social responsibilities, but RCS does not require it.   ◆GRS certification has provisions for the use of chemicals in the process, but RCS does not require it.   ◆ The two have different certification labels.

Growing environmental concerns and the need for sustainable materials, continuous innovation by automotive manufacturers and suppliers, and the increasing viability of post-consumer recycled (PCR) carbon fibers in mass production offer significant advantages for weight reduction, fuel efficiency, and overall sustainability.       The rise of PCR carbon fiber in automotive applications   Carbon fiber has traditionally been favored in the automotive industry for its lightweight and high-strength properties, especially in high-performance and luxury models. However, the production process of native carbon fiber is energy-intensive and expensive, which has led to greater interest in PCR carbon fiber as a more sustainable alternative material. PCR carbon fiber is made from recycled materials that are often sourced from industries that use carbon fiber extensively, such as aerospace or wind energy. This recycling process not only helps to reduce waste, but also significantly reduces the carbon footprint of manufacturing new carbon fiber parts.       Latest progress and application   At present, several automotive manufacturers and suppliers have introduced PCR carbon fibers into their production lines. For example, in 2024, Borealis introduced a glass fiber-reinforced polypropylene composite containing 65% PCR for the production of interior parts for Peugeot 3008 models. This initiative marks an important advance in the application of recycled materials in mass production vehicles. In addition, Carbon Revolution, a leader in carbon fiber wheels, has expanded its production capacity in Mexico to meet the growing demand for carbon fiber wheels in various automotive markets. Their product has now been used in the latest Range Rover model, demonstrating the increasing acceptance of carbon fiber in mainstream car design.       Environmental and performance benefits   The use of PCR carbon fibers in automotive applications brings multiple advantages. From an environmental point of view, it helps reduce reliance on primary materials and lower greenhouse gas emissions generated during production. This is in line with the overall trend towards sustainability in the automotive industry, where automakers are increasingly under pressure to meet stringent environmental regulations. From a performance point of view, PCR carbon fibers retain many of the excellent properties of native carbon fibers, such as a high strength-to-weight ratio, which is crucial for improving vehicle efficiency. Lighter vehicles consume less fuel and have lower emissions, making them more environmentally friendly. This is especially important as the automotive industry transitions to electric vehicles, where reduced weight can directly translate into longer battery range.       Challenges and prospects   Despite the many advantages of PCR carbon fiber, its application in the automotive industry still faces challenges. The recycling process may reduce the properties of the material, making it less suitable for certain high-stress applications. In addition, the cost of recycling and processing PCR carbon fiber remains a major barrier to its widespread use. However, with the deepening of research and technological advances, these difficulties are expected to be overcome. Companies like Toray Industries and Teijin Co., Ltd. are investing in innovative recycling technologies to improve the quality and performance of PCR carbon fibers. At the same time, as the automotive industry continues to prioritize sustainability, the demand for recycled materials is likely to increase further, driving the widespread adoption of PCR carbon fibers.   PCR carbon fiber is expected to play a key role in the future of automotive manufacturing. As more companies embrace this sustainable material, we can expect its application to expand from the niche market to a wider, more mainstream automotive application. This trend reflects the automotive industry's commitment to reducing environmental impact while still maintaining high performance standards.

Honeywell has partnered with a number of energy companies and plastic recycling companies to establish recycling plants that use the UpCycle process technology to convert waste plastics into recycled polymer raw materials.       Chemical recycling is a process in which waste plastics undergo a series of chemical transformations to regenerate new plastics of the same quality as petroleum-based plastics, also known as "advanced cycle" and "molecular cycle", which are complementary to physical recycling. Of the nearly 370 million tons of plastic produced globally each year, less than 10% can be recycled. In recent years, due to the world's multinational policies and the international mainstream petrochemical, brand and packaging giant enterprises to invest heavily and other factors, the chemical recycling of waste plastics has become a hot topic of global concern.       1. On November 3, 2021, Honeywell announced the successful commercialization of a disruptive plastic recycling process. Honeywell's UpCycle process technology uses industry-leading molecular transformation, pyrolysis and contaminant management technologies to convert waste plastics into recycled polymer feedstock that can then be used to make new plastics. The UpCycle process technology significantly broadens the range of plastics that can be recycled, including waste plastics that would otherwise not be recycled, coloured, flexible, multilayer packaging or polystyrene. When combined with other chemical and mechanical recycling processes and improvements in collection and sorting, UpCycle technology is expected to increase the proportion of plastic waste that can be recycled globally to 90 percent.       2. In November 2021, Honeywell and Sacyr announced a joint venture in Andalusia, Spain, to build and operate a plant capable of processing 30,000 metric tons of mixed waste plastics per year, with production expected to begin in 2023. The plant will use Honeywell's chemical recycling UpCycle process technology to convert waste into recycled polymer feedstock, or RPF. Honeywell has already entered into strategic agreements with Total Energy and French chemical company TotalEnergies. Honeywell will provide RPF for Total Energy, TotalEnergies, which will source the feedstock and convert it into high-quality polymers suitable for high-specification applications such as food-grade packaging.       3. On February 17, 2022, Honeywell announced that it will form a joint venture with Avangard Innovative, the largest plastics recycling industry leader in the United States, to build an advanced recycling plant in Texas, USA. The new plant, which will use UpCycle process technology, is expected to be operational in 2023 and will convert 30,000 metric tons of mixed waste plastic per year into Honeywell recycled polymer feedstock.       According to the global management consulting firm McKinsey's forecast for 2030, China will become the largest potential profit pool (chemical recycling), chemical recycling market potential is huge, may be the next 5-10 years in the field of sanitation solid waste one of the few blue ocean, the world's largest market in China.

CNC engraving machine is good at small plastic injection molds finishing, with ability of milling, grinding, drilling and high-speed tapping, is widely used in 3C industry, plastic molds industry, medical industry and other fields.    1- What is the main difference between CNC engraving and CNC milling? CNC engraving machining and CNC milling machining have adopted milling processing principle. The main difference is in diameter of the tool used, of which commonly used tool diameter range of CNC milling is 6-40mm, while the tool diameter of CNC engraving is 0.2-3mm.   2. CNC milling can only do rough machining, CNC engraving can only do fine machining? Before we can answer this question, let's first understand the concept of the process. The processing amount of roughing process is large, and the processing amount of finishing is small, so some people habitually consider roughing as "heavy cutting" and finishing as "light cutting". In fact, roughing, semi-finishing and finishing are process concepts, which represent different processing stages. Therefore, the accurate answer to this question is that CNC milling can do heavy cutting, but also can do light cutting, and CNC engraving can only do light cutting.   3. Can CNC engraving processing do rough processing of steel materials? Judging whether CNC engraving processing can process a certain material, mainly depends on how much tool can be used. The tool used in CNC engraving processing determines its maximum cutting capacity. If the mold shape allows the use of a tool with a diameter of more than 6 mm, it is strongly recommended to first use CNC milling, and then use the engraving method to remove the remaining material. 4. Can the spindle of CNC machining center increase a speed head to complete the engraving processing? Can't finish. This product appeared at the exhibition 2 years ago, but it was unable to complete the engraving process. The main reason is that the design of CNC machining center considers its own tool range, plus wechat: Yuki7557 send a macro program tutorial, the overall structure is not suitable for engraving processing. The main reason for this wrong idea is that they mistook the high-speed motorized spindle as the only feature of the engraving machine. 5. CNC engraving can use a small diameter tool, can it replace EDM? Can't be replaced. Although engraving reduces the diameter range of the milling tool, small molds that were previously only available for electrical spark machining can now be achieved with engraving machining. However, the length/diameter ratio of the engraving tool is generally about 5:1. When using a small diameter tool, only a very shallow cavity can be processed, and the EDM process has almost no cutting force, as long as the electrode can be manufactured, the cavity can be processed.

In plastic mold design,  angle lifter is a common mechanism for ejecting plastic parts that cannot be removed from the mold by direct ejecting. The sloping top is especially suitable for those plastic parts with complex concave shapes, such as mobile phones, automotive interiors and other products. This paper will introduce the design concept, structure, operation flow and maintenance points of the inclined top in detail.   The main purpose of angle lifter is to make the inner surface of the plastic part gradually separate from the mold cavity during the ejecting process of the plastic part. Angle lifter mechanism is usually designed at a certain Angle with the opening and closing direction of the mold, and the plastic part is gradually demoulded through the movement of the inclined plane.   Angle lifer mechanism is mainly composed of the following parts: angle lifter block: the main part that contacts with the inner surface of the plastic part and pushes the plastic part out of the mold. Inclined ejector rod: Connects the inclined ejector block and ejector system to transmit the ejector force. Inclined top guide system: Ensures that the inclined top block moves in the correct direction during ejection and resetting. Inclined top spring: provides the reset force for the inclined top block to ensure that the inclined top block can return to the original position smoothly. Inclined top seat: Fix the inclined top block so that it is correctly positioned in the mold.

BASF cooperated with Li Ning, a leading professional sports brand in China, to develop a full thermoplastic polyurethane concept shoe (full TPU shoe), which is made entirely of BASF Elastollan® TPU material and can be 100% recycled. Together with Hamee, BASF has developed a bio-based TPU that can be used in the manufacture of mobile phone cases. With a renewable raw material ratio of 53%, the TPU has excellent UV and yellow resistance while maintaining the wear resistance and high transparency of the phone case.   Automotive is an important end area for BASF TPU applications. Basf Greater China thermoplastic polyurethane business management director Zhuang Wei said in an interview with the media group that from the perspective of visual experience, BASF's TPU products can make light guide strips or light guide films for atmosphere lamps, which also shows that the TPU has good optical performance from the side. In addition, TPU can also be used to make protective film and color changing film for automotive paint.       "Because TPU has a better brightening sense and can bring better visual touch to users, from the future trend, TPU will gradually replace traditional PVC materials." "Zhuang Wei added. He said that although there is no specific figure for the proportion of TPU in the vehicle material at present, whether it is a brake line, a transmission line, a car casing or even a spiral car charging line, TPU can be made. TPU can also be used to make car seats, such as the leather of the door panel inside the seat, the handle or the related soft glue.  

Coca-Cola has launched a 500ml soft drink bottle in Hong Kong made from 100% recycled rPET, the latest effort by the company to improve the sustainability of its beverage packaging.   Coca-Cola has always been committed to its strategic vision of a "waste free world" through bold and innovative sustainable development.   The original, sugar-free and plus 500ml versions of Coca-Cola sold in Hong Kong will all switch to 100% recycled PET for the bottle body, with the exception of the cap and label.     This recycled plastic bottle is prominently printed with the logos "I am a 100% recycled PET bottle" and "Recycle Me Again", aiming to raise public awareness of recycling and inspire consumers to actively participate in environmental action.       According to Coca-Cola, the main purpose of using 100% recycled plastic bottles is to reduce plastic pollution in the environment and set an example for other beverage brands to develop green.   To accelerate the circular economy of plastics in the city, Coca-Cola has partnered with Waste Free in Hong Kong and plans to invest HK $3 million in 2024 to support a new neighbourhood collection scheme.       The program aims to cultivate recycling habits by mobilizing residential building users, cleaners and residents' families to participate in recycling activities, and invites Hong Kong residents to participate in the recycling and separation of plastic bottles, and jointly build a "recycling" system for plastic bottles.       In addition, Coca-Cola has invested in Hong Kong's largest quasi-food-grade plastic recycling facility, Plastic New Life. As an important part of Coca-Cola's "Waste Free World strategy", the company has sufficient recycling capacity to ensure that every PET bottle sold by Coca-Cola can be effectively recycled.   So far, Coca-Cola has launched 500 ml rPET plastic bottles in Canada, the Philippines and Myanmar.   The Hong Kong government will launch the Municipal Solid Waste charging scheme on August 1, 2024, which Coca-Cola believes is expected to provide more resources for recycled PET, which will help it produce more 100% recycled plastic bottles.  

According to the latest data released by the China Association of Automobile Manufacturers, China exported 443,000 vehicles in January 2024, an increase of 47.4% year-on-year.       In fact, in 2023, China's auto exports have been "leading all the way", an increase of 57.9%, surpassing Japan for the first time, ranking first in the world.       Among them, the annual export of new energy vehicles was 1.203 million, an increase of 77.6%.       The domestic market has become white-hot, and the overseas market has become the sweet cake for Chinese car companies to go to sea to seek gold     Among the top 10 countries in automobile exports, the Russian market performed strongly, growing 5.5 times year-on-year. The sales of new energy vehicles to Belgium, Thailand and Spain are growing significantly.       From a regional perspective, Europe has a highly inclusive and mature automotive industry base, while the penetration of electric vehicles in Southeast Asia is relatively low, and the local automotive industry is in a relatively weak position.       This makes Europe and Southeast Asia becoming the main battlegrounds for the overseas expansion of Chinese automobiles, especially new energy vehicles.    

Henkel's laundry detergent is now packaged in a single material film containing 30% PCR, developed jointly by Korozo Group and Ecoplast, to comply with the recycling requirements of the Packaging and Packaging Waste Regulation (PPWR).       Ecoplast, a member of the Borealis Group, supplied the PCR material. Its LDPE recycled materials are ISCC Plus and EuCertplast certified, meaning recycled ingredients can be tracked and traced throughout the value chain. The packaging uses the Borcycle CWT100VL grade material because its low gel content is believed to bring high optical and print quality, which enhances its shelf appeal, and has the mechanical properties required to keep the product safe.       Next, Korozo is responsible for laminating the PCR material into a single material structure and printing it on its high-end presses and bag-making lines. Today, Henkel has implemented the new packaging in its laundry detergent brands, such as Persil. The new packaging is already available in Central and Eastern Europe.       "We are excited to leverage our global leadership in flexible packaging to contribute to the creation of this innovative, circular solution," said Fatih lmre, Customer Manager, Consumer Packaging Technology, Korozo Group. "Collaboration across the value chain is essential to deliver sustainable packaging solutions and the transition to a circular economy."       Given the upcoming Packaging and Packaging Waste Regulation, which sets a minimum recycling content in plastic packaging - including 35% PCR material in recyclable film by 2030 - and requires all packaging sold in the EU market to be recyclable, Korozo hopes its solution will help brands comply with these regulations.

French biochemical company CARBIOS, in collaboration with global cosmetics brand L 'Occitane and cosmetic and personal care packaging manufacturer Pinard Beauty Pack, has developed a transparent, recycled polyethylene terephthalate bottle (r-PET bottle) made entirely from an enzymatic depolymerization process.       This move marks another step forward on L 'Occitane's path to achieving its 2027 goal of packaging made from 100% post-consumer recycled r-PET.       According to Carbios, the industrial demonstration plant in Clermont-Ferrand, France, is responsible for the collection and treatment of difficult-to-recycle waste, such as coloured bottles, multi-layer pallets and mechanically recycled residues, which are collected, sorted, prepared and depolymerized using Carbios's biorecycling technology. This innovative process complements mechanical recycling technology, as it can process coloured, multilayer and textile waste that cannot be recycled using traditional methods, resulting in the original monomers PTA and MEG. These monomers are repolymerized into new PET resins in the European supply chain. Pinard Beauty Pack uses these repolymerized PET resins to produce food-safe PET packaging of the same quality as petroleum plastics. Particles are blown into bottles according to L 'Occitane's packaging specifications, and L 'Occitane fills the bottles with bath oil.       Since the collection and treatment from the source, recycling and recycling, and then the production of packaging products are all completed in the local area, the transportation time and production time are greatly reduced, which can greatly reduce carbon emissions. Compared to the original plastic production, the enzymatic depolymerization process can reduce carbon dioxide emissions by 57% and avoid 1.3 tons of oil per ton of recycled r-PET produced.       David Bayard, R&D Packaging Director at L 'Occitane, said: "We are proud to be part of this forward-thinking industry. Today, more than 50% of our PET comes from recycled materials. Thanks to CARBIOS and decopolymerization, we are able to reduce our reliance on fossil plastics and provide a viable alternative with the same quality and transparency that is important for our products."       Paolo Coelho, plant director at Pinard Beauty Pack, added: "The parameters of this bottle blow molding are consistent with either native PET or mechanically recycled r-PET, which is a considerable advantage for Carbios's innovative technology. We are seeing a strong demand for high-quality recycled PET."

In recent years, with the development and versatility of the plastic industry. The application range of plastic products is more and more extensive, such as: household appliances, instrumentation, construction equipment, automotive industry, daily hardware and many other fields, the proportion of plastic products is rapidly increasing. However, with the rising trend of plasticization of industrial products and daily products, the strength and accuracy of plastic products are also constantly improving, therefore, in order to make the mold obtain better strength and accuracy, it is necessary to carry out two-color mold injection molding process. What is the two-color mold injection molding process?   Two-color mold or two shot mold injection molding process:   Mold is a tool for the production of plastic products, which is generally composed of several groups of parts, and this combination has a molding cavity. During injection molding, the two-color mold is clamped on the injection molding machine, the molten plastic is injected into the molding cavity, and the cooling and shaping in the cavity, and then the upper and lower molds are separated, and the products are ejected from the mold cavity through the ejecting system, and the mold is closed for the next injection molding, the whole injection molding process is cyclic.   In the process of injection molding production, plastic raw materials, toner, nozzle material, mold, injection molding machine, peripheral equipment, fixture, spray, various auxiliary materials and packaging materials are used. In order to make the production and operation of the injection workshop smooth, it is necessary to manage the personnel, materials, equipment and tools involved in each link and each post, mainly including: raw material room, crushing room, batcher room, production site, post-processing area, tool room, semi-finished product area, office and other areas of operation and coordination management.   Because the mold or semi-finished product needs to be rotated, the mold design and injection molding machine requirements are more precise. In addition, due to the high variability of two-color mold injection molding, in order to achieve smooth production and meet the expected ideal, all mold design must be considered simultaneously with product design.   The content described above is the two-color mold injection molding process. With the continuous maturity of China's two-color mold injection molding process, China is gradually becoming a global manufacturing base for consumer products, in recent years, manufacturers of plastic products in South China have undertaken many orders requiring two-color mold injection molding skills, so that China's two-color mold injection molding technology should be more refined.
