PTFE, stainless steel


Laser Seal Ring Product Introduction The sealing ring is installed in the drawer of the protective lens, and through the interference fit with the lower protective lens, the protective lens under the focusing lens is sealed to prevent dust and unclean gas from contaminating the cutting head cavity, resulting in the burning of the quasi focus mirror and the collimator group. Features The main material is imported high purity transparent PTFE. The spring is made of stainless steel with ultra-thin, high hardness, good flexibility, and high yield strength. Its main features are the wear resistance of the material; the surface is smooth and the friction is small; the spring elasticity is appropriate. There are no problems such as large extraction resistance and poor sealing effect. High-temperature formula: modified PTFE + stainless steel spring. Low-temperature formula: polymer material + stainless steel. Pressure range: 0-45MPA Temperature range: High-temperature formula (-150~+280 degrees) Low-temperature formula (-196~+150 degrees)
