Piston ring is used to insert metal rings inside the Piston groove，it is a kind of metal elastic ring with large outward expansion deformation, which is assembled into the section and its corresponding annular groove.
The piston rings of reciprocating and rotating motions, depending on the pressure of the gas or liquid, are sealed between the outer circular surface and the cylinder and one side of the ring and the ring groove.
25years of professional production experience.
Strictly according to TS 16949 international quality system to carry out quality control, strict operation staff self-inspection, process inspection, complete inspection, shipment sampling inspection and other links,At the same time, the special characteristics of piston ring (such as nitriding layer, chromium-plated layer thickness, hardness, crystalline phase, elasticity, thermal stability, etc.) are strictly examined to ensure the long service life of piston ring
