What plastics are used for injection molding at Auto Parts Mould Company?
Plastic component manufacturers most commonly use thermoplastics for injection molding. Thermoplastics are polymers that melt at high temperatures and cure at low temperatures. Unlike thermoset materials, which burn if reheated, you can heat and cool thermoplastics multiple times before they degrade and become unusable.
You most often see thermoplastics in the form of plastic pellets used for injection molding. You can mix plastic pellets with colorants, recycled materials and even glitter or other special additives.
The most common types of thermoplastics are:
○ Acrylonitrile Butadiene Styrene (ABS)
ABS is a rigid and lightweight material. It is a very popular plastic injection molding material. Did you know that Lego bricks are made of ABS?
automotive polycarbonate
Polycarbonate is a transparent thermoplastic. They are impact resistant and can withstand high levels of plastic deformation without breaking or cracking. Manufacturers often use this thermoplastic in eyeglass lenses, medical devices and mobile devices. You can even use it to make bulletproof glass!
○ Nylon
Nylon has unique electrical properties and is tough. From sports equipment to industrial components, you'll find a wide range of applications for this thermoplastic.
○ Polypropylene
Polypropylene is a flexible material. It also has good chemical resistance and won't seep into food, making it ideal if you want to make food containers or cutlery.
○ Polyethylene
Polyethylene is one of the most versatile plastics used for injection molding. Polyethylene's high ductility, tensile strength, impact resistance, low moisture absorption and recyclability make it an ideal material for plastic containers and bags.
