There are many forms of rubber gaskets, such as some commonly used rubber flat gaskets, rubber O-rings, plastic flat gaskets, PTFE-coated gaskets, asbestos rubber gaskets, metal flat gaskets, metal special-shaped gaskets, Metal sheathed washers, wave washers, spiral wound washers, etc.

The rubber flat gasket is easy to deform and does not require any effort during compression, but it has poor pressure and temperature resistance. It is only used in places with low pressure and low temperature. Natural rubber has certain acid and alkali resistance, and the use temperature should not exceed 60°C; chloroprene rubber can also be resistant to certain acids and alkalis, and the use temperature is 80°C; nitrile rubber is oil-resistant and can be used up to 80°C; fluororubber has good corrosion resistance and resistance The temperature performance is also stronger than that of general rubber, and it can be used in 150℃ medium. The rubber gasket has oil resistance, acid and alkali resistance, cold and heat resistance, aging resistance and other properties, and can be directly cut into various shapes of sealing gaskets, which are widely used in medicine, electronics, chemical, antistatic, flame retardant, food and other industries.

The manufacturing method of rubber gaskets is made by molding and cutting. The molding is made by using a hydraulic forming machine and a mold. The cutting is cut by a gasket cutting machine. In comparison, the molding saves materials, but compared A single mold can only make one type of gasket. The gasket cutting machine can cut any size within the specified range, but the utilization rate of the plate is not very high.
