The principle of achieving "self-sealing" effect: The pressure type seal in the contact dynamic seal is the contact pressure formed between the seal and the coupling surface through the pressing force generated by the pre-compression force and the medium pressure. The higher the medium pressure, the greater the contact pressure, which makes the seal The parts are tightly fitted with the coupling to block the leakage channel and achieve a "self-sealing" effect. The self-sealing self-tightening seal uses the back pressure generated by the deformation of the seal itself to increase with the increase of the medium pressure, so as to achieve the "self-sealing" effect.

The main professional processing equipment includes flat vulcanizer, injection molding machine, rubber and plastic pressurized kneader, rotorless vulcanizer, tensile testing machine...
