An introduction to how the seal is produced

How the seals are produced, not all seals can be machined by punching, only if the diameter requirements are not strict. Next, we will introduce how to make a seal using the punching method:
         (1) Protective ring made of leather and fluoroplastic board.
         (2) Flat gaskets made of rubber asbestos sheets, thin aluminum sheets, and copper sheets.
         (3) Rectangular section seals made of rubber sheets.
     It should be noted that the dimensional accuracy of the seals produced by the die cutting method is low. Seals are therefore suitable for single piece, new product trials and old product improvements.
