Advantages of injection molding in automotive applications
Injection molding is a well-established production process in which an automotive mold maker injects molten plastic material into a mold cavity. The molten plastic then cools and hardens, and the manufacturer removes the finished part. While the mold design process is critical and challenging (poorly designed molds can lead to defects), injection molding itself is a reliable method for producing solid plastic parts with a high-quality finish.
Here are a few reasons why the process is beneficial for the production of automotive plastic parts:
1. Repeatability
In the automotive industry, repeatability - or the ability to consistently produce the same part - is critical. Because automotive plastic injection molding typically relies on a robust metal mold, the final molded automotive part produced using that mold is virtually identical. Some factors can affect injection molding, but if the mold has good design and finishing, injection molding is a highly repeatable process.
2. Size and Cost
The injection molding process can be an expensive process due to the cost of the mold. However, it is still a highly scalable process, and as manufacturers make more parts, their overall cost decreases. Therefore, for mass production applications, injection molding can be beneficial to the manufacturer. However, for any non-mass-produced product, injection molding tooling costs may limit the cost efficiency of the process.
3. Material Availability
A significant advantage of using injection molding in automotive production is the wide variety of rigid, flexible and rubber plastics that the process is compatible with. Manufacturers use a variety of different polymers for various applications in the automotive industry, including ABS, polypropylene, acrylic, acetal, nylon, polycarbonate and more.

POM Regrind from zipper Teeth, industry lump, industry runner Definition of POM resin (polyformaldehyde resin): polyformaldehyde is a linear polymer without side chain, high density and high crystalline properties. According to different chemical structures in the molecular chain, there are two types of homoformaldehyde and copolymers. of both types of polyformaldehyde density, high crystallinity, melting point, but thermal stability, the treatment temperature range is narrow (about 10oC), slightly lower in acid and alkali stability; The density of formaldehyde, melting point, strength and copolymer is lower, but good thermal stability, not easy to decompose, wide range of treatment temperature (about 50oC), acid and alkali stability are good . Plastic has excellent all-round performance. Good physical, mechanical and chemical properties, especially with excellent friction resistance. It is commonly referred to as steel or strip, which is the general engineering plastic third. Suitable for reducing wear on parts, transmitters, chemicals, tools and other parts. One of the synthetic resins, also known as polyformaldehyde resin, POM resin and steel, etc. This is a kind of white or black plastic resin with high hardness, high steel and high wear resistance. Used for gears, bearings, auto parts, machine tools, tools, etc. MATERIAL: POM Regrind from zipper Teeth , industry lump, industry runner CATEGORY: POM TYPE: Regrind SPECIFICATION: from zipper Teeth , industry lump, industry runner,Qty per month 52 mt Origin: Bangladesh LOADING WEIGHT: 24 Ton FOB (USD/Ton): 650$ - 850$ Packaging: Jumbo Bag Est.

ABS Regrind ,Yes No Fr, NO pc abs, no iron, no circuit etc ABS has excellent mechanical properties, excellent impact resistance and can be used at extremely low temperatures. ABS has excellent wear resistance, good dimensional stability and oil resistance, and can be used for bearings under medium loads and speeds. ABS's creep resistance is greater than PSF and PC, but smaller than PA and POM. The flexural and compressive strength of ABS are poor in plastics. The mechanical properties of ABS are greatly influenced by temperature. ABS is flammable material and belongs to HB class according to UL94 standard. ABS burns quickly when ignited, and emits a lot of toxic gases and black smoke, which is not conducive to practical application. With the advancement of science and technology and improving the quality of life, everyone's safety awareness is getting stronger. The domestic and foreign countries have put in place strict fire and flame retardant requirements for plastic materials used in automobiles, construction, home appliances, office supplies, etc., and made corresponding technology. Standards and specifications, so research on ABS flame retardants has a very important meaning.
