In today's automation industry, plastic balls are often widely used in the production of industrial seal valves. In the design of products, such as electronic valves,an electric appliance，valve，bathroom, faucet and other products, plastic ball plays the role of sealing and leak proof. The plastic ball is a product with a little hardness. When it is matched with another product, the material of the other product is better, which is metal, rubber and silica gel. The hardness of the ball is either higher or lower than that of the plastic ball. Only in this way can the plastic ball play a better role.

The solution of plastic ball in the production of industrial seal valve:

1. The tolerance of plastic ball should be within / - 0.03mm.

2. The surface finish of plastic ball is within Ra0.025, in micrometers.

3. Choose the plastic materials that are more suitable for your products to produce plastic balls. Plastic materials such as POM, PP, PE, nylon, PA66, nylon, ABS, PS, PMMA, PVC, etc

4. It is necessary to control the dimensional tolerance of the parts matched with the plastic ball, which is generally within / - 0.25 mm.
