1. Graphite nylon is a kind of nylon plastic containing filler, which is used to press tight mechanical parts. The filler is graphite with high content, which makes this material have strong bearing capacity.

2. The concentric circular washer, which is formed by the circular stamping of the upper die and the lower die after the graphite nylon sheet is informed by the graphite nylon washer to the stamping part to open the die, is widely used in the motor. Its greater feature is that the graphite nylon has good light, wear resistance, rubbing resistance, softness and weather resistance. In addition, graphite nylon can increase the strength, but the water absorption is still very large, which is mainly determined by the performance of nylon. Sometimes, in order to increase the size of products, it is deliberately cooked in hot water, so that it can increase about 1%, and the toughness and wear resistance are increased.
