Automotive plastic parts are various plastic components widely used in automobile manufacturing, characterized by their light weight, low cost, high design flexibility, and corrosion resistance. They effectively reduce vehicle energy consumption, improve production efficiency, and meet a variety of functional and decorative requirements.
The length of bumpers is typically between 1.5 to 2.5 meters (to fit different vehicle axle distances), while the width of dashboards matches the lateral dimensions of the driver’s cabin (approximately 1.2 to 1.8 meters); small functional parts (such as clips, washers) may only be a few centimeters in size.
The material of automotive plastic parts is selected based on functional requirements, with common types including:
Polypropylene (PP):
The most widely used, accounting for over 30% of automotive plastic parts, such as bumpers, dashboards, door panels, etc.
Features: Low cost, low density (lightweight), good chemical resistance, and can have their strength enhanced by adding glass fiber (PP+GF).
Acrylonitrile-butadiene-styrene copolymer (ABS):
Used for decorative parts (such as center console panels), instrument housings, etc., with good surface gloss and impact resistance, easy to paint and electroplate.
Polyamide (PA, nylon):
PA containing glass fiber (PA+GF) is commonly used for engine peripheral components (such as intake pipes, oil pans), with high temperature resistance, wear resistance, and high strength.
