Hongwo Sealing Gasket
PTFE (Polytetrafluoroethylene) gasket is popular sealing materials. It has excellent corrosion, temperature, and dimensional stability. The following is the general production process for PTFE gasket:
1. We select high-quality PTFE resin as the raw material. They crush and grind the resin into a powder.
2. Pressing and Forming: A mold holds the PTFE powder. They press it at high temperatures and pressure. The powder melts during pressing. It fills the entire mold, forming a uniform thickness.
3. Cooling and Solidification: A cooling environment solidifies the pressed PTFE gasket. This ensures its shape and stability. You need to control the cooling time and temperature according to specific requirements.
4. Post-Processing: After solidification, the PTFE gasket may have some uneven areas. They need trimming and polishing. Common post-processing methods include cutting, punching, and grinding.
5. Quality Inspection: We must inspect the completed gaskets. This is to ensure they meet the performance and size requirements. Common inspection items include density, pressure resistance strength, and dimensional deviation.
6. Packaging and Storage: We package the completed gaskets to prevent contamination and damage. Store them in a dry, well-ventilated warehouse. Avoid contact with other items and deformation.
The above is the general production process of PTFE gaskets. Due to differences among various manufacturers, specific process details may vary. In use, we need strict quality control. It ensures the gaskets’ stable, reliable quality.
