What are the considerations for choosing auto parts?

See if the geometric size is deformed. Some parts are easily deformed due to improper manufacture, transportation and storage. During inspection, the shaft parts can be rolled around the glass plate to see whether there is light leakage at the joint of the auto parts and the glass plate to judge whether it is bent; when purchasing the clutch driven disc steel sheet or friction sheet, the steel sheet can be , Hold the friction plate in front of your eyes to observe whether it is warped; when purchasing oil seals, the end face of the oil seal with the skeleton should be in a perfect circle, which can fit with the flat glass without deflection; Its deformation should be able to return to its original state after letting go. When purchasing all kinds of pads, you should also pay attention to checking the geometric size and shape.

Rearview mirror folder manufacturers introduce to see if there is rust on the surface of the parts. The surface of qualified spare parts has both a certain precision and a bright finish. The more important the spare parts are, the higher the precision is, and the stricter the packaging is to prevent rust and corrosion. When purchasing, you should pay attention to inspection. If the parts are found to have rust spots, mildew spots or cracks in the rubber parts, loss of elasticity, or obvious turning tool lines on the surface of the journal, they should be replaced.

Check whether the trademark logo is complete. The quality of the outer packaging of the authentic product is good, the writing on the box is clear, and the overprint color is bright. The packaging box and bag should be marked with the product name, specification, model, quantity, registered trademark, factory name, address and telephone number, etc. Some manufacturers also mark their own marks on the accessories. Some important components, such as generators, distributors, fuel injection pumps, etc., are also equipped with instruction manuals, qualification certificates and inspector seals to guide users in correct use and maintenance. When purchasing, it should be carefully recognized to prevent buying fake and shoddy products.

Check to see if the joint is flat. During the handling and storage of spare parts, due to vibration and bumping, burrs, indentations, damages or cracks are often generated in the joint parts, which affects the use of the parts. Pay attention to inspection when purchasing
