Plastic balls are mainly divided into:

POM plastic ball, PA plastic ball, PP plastic ball, PE plastic ball, PTFE PTFE plastic ball, Teflon plastic ball, acrylic plastic ball.

Plastic balls are linear polymers with high hardness and rigidity, high creep resistance and stress relaxation resistance, excellent wear resistance, self lubrication, fatigue, high density and high crystallinity. Plastic balls have good comprehensive properties and fatigue resistance. It can withstand repeated impact for many times, and the change of strength is very small. The precision of the plastic ball is + / - 0.02 to 0.001 mm. There is no clamping line, no burr, smooth surface, high technology and high quality. It is provided to high-precision customers! It is mainly used in automobile, sensor, valve, pump, bathroom, electronics, bearing, electrical appliance, and other industries

POM plastic (polyoxymethylene) (saigang Trane) English Name: Polyoxymethylene (polyformaldehyde) POM (polyoxymethylene resin) definition: polyoxymethylene is obtained by polymerization of formaldehyde. It is a thermoplastic engineering plastic with high density and high crystallinity. It has good physical, mechanical and chemical properties, especially excellent friction resistance. It is precisely because these excellent chemical and physical properties can be comparable to steel, and the weight is lighter than steel that they are called "saigang"! Specific gravity: 1.41-1.43 g / cubic centimeter molding shrinkage: 1.2-3.0% molding temperature: 170-200 ℃ drying conditions: 80-90 ℃ for 2 hours. The material has good comprehensive properties, high strength and stiffness, good wear reduction and wear resistance, small water absorption and good dimensional stability, but it has poor thermal stability, easy combustion and easy aging in the atmosphere. It is suitable for making anti-wear and wear-resistant parts, transmission parts, chemical industry, instruments and other parts. Molding performance 1 Crystallized material has narrow melting range, fast melting and solidification, and crystallization occurs when the material temperature is slightly lower than the melting temperature. Medium liquidity. The moisture absorption is small and can not be dried. 2. Low friction coefficient, good elasticity, and surface defects with wrinkles on the surface of plastic parts. 3. It is easy to decompose, and the decomposition temperature is 240 ℃. There are irritant and corrosive gases during decomposition. Therefore, the die steel should be made of corrosion-resistant materials.
