Selection method of automobile plastic parts:
1. Look at appearance
The surface of qualified parts has clear and regular printing or casting and marking, which has a certain precision and a bright finish. The more important parts are, the higher the precision, and the stricter the anti-rust and anti-corrosion of the packaging. If the parts are found to have rust spots or rubber cracks, loss of elasticity, or obvious cutting tool lines on the surface of the journal, they should be returned for replacement.
2. Look at the packaging
The packaging of original accessories is generally standardized, unified standard specifications, and the printing is clear and formal. It should be marked with product name, specification model, quantity, registered trademark, factory name, factory address and telephone number, etc. Some manufacturers also type their own on the accessories mark.
3. Look at the paint
The unscrupulous merchants simply processed the waste parts, such as dismantling, assembling, assembling, putting together, painting, etc., and then posing as "qualified products". After peeling off the surface paint, the old paint can be found.
4. Look at the craftsmanship
Although the appearance of inferior products is sometimes good, due to poor production technology, cracks, sand holes, slag inclusions, burrs or bruises are prone to appear. If the cylinder gasket is squeezed and deformed, it is easy to cause the sealing and ablation during use, resulting in oil leakage, air leakage and water leakage.
