Common Plastic Resins Used in Injection Molding
Once you find an overseas manufacturer to assist you with your plastic injection molding needs, you’ll have to decide on the type of plastic resin you’d like to use. Some of the most popular materials used include:
ABS (Acrylonitrile Butadiene Styrene)
Looking for a plastic resin with outstanding impact and mechanical strength? Acrylonitrile Butadiene Styrene, also known as ABS, can be used for a wide range of industries and applications. Many people like this resin because metal coatings can easily adhere to this material, making it suitable for products like phones, shower heads, and cabinet handles. It’s important to note that ABS does not have great chemical resistance properties, and you should avoid using this material in applications that require electrical insulation or UV resistance.
Popular applications: handheld devices, moldings for electrical tools, computers, remote controls, telephone parts, and cosmetic parts.
Also known as Celcon, Acetal, is an ideal resin for a number of industries. This material offers incredible surface lubricity and chemical solvent resistance, and is ideal for food and beverage products, mechanical parts, automotive components, and household applications. This material should not be used for applications in high heat and temperature environments.
Popular applications: automotive parts, bearings, zippers, conveyor moving parts, gears, and pump and valve parts.
Polypropylene is most often found in packaging but this resin can be used for several different applications. It’s very easy to inject this material into a mold, and it is highly resistant against other materials like acids and bases. With a high level of material strength, this can be a very cost-effective option for people who need plastic injection molds. It’s important to note that polypropylene is flammable and can be vulnerable to UV radiation.
Popular applications: fans, shampoo bottle tops, battery cases, paint cans, home storage options, and speakers.
High Impact Polystyrene
Looking for a versatile, economical, and impact-resistant plastic for your mold? High impact polystyrene, also known as HIPS, may be the right material for you. Normally used for low strength structural applications, HIPS offers great impact resistance, excellent dimensional stability, and tends to be very affordable.
Popular applications: gasoline tanks, computers, cups, toys, and automotive parts.
Polyvinyl Chloride (PVC)
Also known as PVC, polyvinyl chloride, is a resin that offers moderate resistance to impact, and has a low-to-medium strength and impact on mold. Known for its low cost, this resin is UV resistant and can be used to add strength to a variety of materials. It can also be used for containers, fencing, and other flexible parts.
Popular applications: electronics, automobile parts and components, wire and cable insulation, water pipes, household products.
