PTFE Piston Rings

1. The outer surface of the piston ring is covered with a layer of polytetrafluoroethylene material. This layer of material has good wear resistance, corrosion resistance, and low friction coefficient, and can protect the piston and the inner wall of the cylinder from wear.

2. The cross-sectional shape of the PTFE piston rings is usually circular, rectangular, trapezoidal, or wedge-shaped, etc. These shapes can ensure good contact between the piston ring and the inner wall of the cylinder, thus playing a sealing role.

3. The size and accuracy of piston rings are very high, and they are generally made of precision casting or CNC machine tools to ensure that their geometric shape and dimensional accuracy meet the requirements.

4. The surface treatment of the piston ring is also very important. It usually requires chrome plating, spraying a wear-resistant layer, and other treatments to improve its wear resistance and service life.

In short, the structural features of PTFE piston rings include PTFE coverage on the outer circumferential surface, specific cross-sectional shape, high-precision dimensional requirements, and surface treatment. These characteristics enable piston rings to adapt to various harsh environments and harsh working conditions and are widely used in various industrial fields.

1. Ingredients: Mix PTFE rubber resin, additives, fillers, etc. in a certain proportion evenly.

2. Hot pressing molding: Put the prepared materials into the mold, heat, and press to form.

3. Cooling: Place the hot-pressed piston ring into cooling water to cool.

4. Cutting: Cut the piston ring to the required size.

5. Processing: Process the cut piston rings, such as drilling, turning, etc.

6. Inspection: Inspect the processed piston rings to ensure they meet the requirements.
