The varying plastic types used in custom injection molding allow for various melting points required for different applications.

Acrylonitrile Butadiene Styrene (ABS): A common thermoplastic used for products that do not require chemical, electrical, or UV resistance. ABS is a flexible and lightweight material with good impact strength and durability. Many everyday objects use ABS custom injection molded parts, such as children’s toys, components in household appliances, and automotive parts.
Low-Density and High-Density Polyethylene (LDPE and HDPE): As one of the most versatile thermoplastics, LDPE and HDPE have high tensile strength, impact resistance, and moisture resistance. HDPE is a material used in a range of consumer and industrial products, while LDPE is a softer version popular in consumer and industrial production.
Polycarbonate (PC): As a transparent, lightweight material, PC is a durable alternative to glass. With high durability and extreme impact resistance, many demanding applications use PC, including bulletproof glass.
Polyamide (Nylon): Nylon offers excellent electrical properties, strength, and resistance to heat wear, and chemicals. Applications in the medical and automotive industries often use nylon for custom plastic injection molded parts.
High Impact Polystyrene (HIPS): As a versatile, impact-resistant, and economical plastic, HIPS consists of crystal styrene and rubber. With non-toxic properties, HIPS is ideal for food-grade components.
Polypropylene (PP): With excellent chemical and stress resistance and high impact strength, PP is a robust plastic with a high melting point. PP is often used as a food-grade polymer in the food and beverage industry.
