PEEK Valve Sealing Rings

Sealing principle

The sealing principle of the PEEK valve sealing ring mainly depends on its material properties and structural design.

First of all, PEEK is a polymer material with excellent heat resistance, corrosion resistance, wear resistance, and other properties. These properties enable the valve sealing ring to maintain stable sealing performance in various harsh working environments.

Secondly, PEEK valve sealing rings adopt an advanced structural design, which can effectively improve sealing performance. For example, a special groove design is used to closely match the valve seat to form an effective seal.

Manufacturing process

1. Material preparation: First, you need to prepare PEEK material, which is a high-performance special plastic with excellent mechanical properties, heat resistance, corrosion resistance, etc.

2. Mold design: Design the mold according to the size and shape of the product to ensure the accuracy and stability of the mold.

3. Injection molding: Put the PEEK material into the mold and mold it through the injection molding machine. During the injection molding process, parameters such as temperature, pressure, and time need to be controlled to ensure the accuracy of product size and shape.

4. Cooling and shaping: After injection molding is completed, the product needs to be cooled and shaped to eliminate internal stress.

5. Demoulding and picking up: After cooling and shaping, take the product out of the mold.

6. Quality inspection: Conduct quality inspection on PEEK valve sealing rings product, including size, shape, surface quality, etc.

7. Packaging and storage: Pack the qualified products and store them in the warehouse.
