Test Background
Wear resistance test is a routine item for surface quality control of automotive interior and exterior plastic parts, and is also an important indicator for quality control of automotive interior and exterior plastic parts. The wear test of automotive plastic products can determine their wear resistance.
Zhongke Testing Reliability Experiment Center has reliability testing capabilities for various plastics and provides professional wear testing services for automotive plastic products.
Scope of tests
1. Polycarbonate plastic: lamps, instrument signs, sun visors, window glass, bumpers, etc.;
2. RIM plastic: bumpers, radiator grilles, spoilers, fenders, etc.;
3. Polyethylene plastic: damping materials for fenders, ceilings and doors, trunk mats, air ducts, gasoline tanks, etc.;
4. Polyvinyl chloride plastic: instrument panel cover, car roof lining, rear cover skin, spare tire cover, steering wheel, bumper cover, wire coating, etc.;
5. Polypropylene plastic: heating and ventilation systems, cabins, engine compartments, car bodies, light housings, tool boxes, wire terminals, junction box covers, silencers, etc.;
6. ABS plastic: rear fenders, instrument panels, radio covers, air exhaust pipes, steering wheel horn covers, grilles, rear guards, upper ventilation covers, wheel covers, blinds, brackets, mirror frames, etc.;
Test method
According to the surface shape of the product and the nature of wear, the test can be divided into 3 forms:
a) Curved surface sliding wear test: Check the sliding wear of the curved surface of the product;
b) Flat sliding wear test: Check the sliding wear of the flat surface of the product;
c) Falling sand wear test: Check the scratch resistance of the product.
