Plastic balls have high hardness and rigidity, high creep resistance and stress relaxation, excellent wear resistance, self-lubricating, fatigue, high density and high crystallinity linear polymers. Plastic balls have good overall properties and fatigue resistance. It is resistant to repeated shocks and has little change in strength. The plastic ball has an accuracy of +/- 0.02 to 0.001 mm, no mold line, no burrs, smooth surface, high technology, high quality, and is available to high-precision customers.
