Problems solved by technology

[0002] The sealing ring is a material or part that prevents fluid or solid particles from leaking from adjacent joint surfaces and prevents impurities such as external dust or water from intruding into the internal parts of the machine equipment. The sealing ring generally works under certain pressure and temperature conditions. Sealing rings with different structures and materials have different sealing effects under different conditions. However, once the sealing ring fails, it will directly affect the use of the equipment.
[0003] At present, the low strength and high pressure of the sealing ring make the sealing effect of the sealing ring unsatisfactory and cannot meet the sealing requirements of the equipment. At the same time, the sealing ring is prone to burrs when forming, and the deburring is done manually, and it is difficult to grasp the size when removing. , prone to defective products
