The inner and outer walls of the cavity lining of the workpiece are under the condition of equal pressure difference. Layer separation problem. The elastic mold makes full use of its elasticity to compress and close the PTFE powder in the cavity. It is widely used in severely corrosive occasions such as petroleum, chemical, pesticide, dye, pharmaceutical, military industry, and pipeline system medium or material transportation.
On the lining wall, and the thickness of the PTFE lining remains the same, it completely solves the problem of the molding technology of the cavity of the complex PTFE Coated Fabric Manufacturers shape workpiece and the problem of inconsistent lining thickness that causes local stress concentration and cracks. The PTFE lining isobaric forming technology can be applied to the cavity forming of valves [...]
