With the continuous development of industry, the traditional way of industrial product technology is constantly replaced by new scientific branches, and some new materials have new uses. As a guide sleeve oil-free self lubrication function in the mold industry, graphite rod has also been paid more and more attention by people, which has brought a new industrial revolution of plastic mold. Without increasing any cost, the service life of mold is also greatly improved With the development of technology, more and more attention has been paid to the application of graphite in mould. Scientific research has proved that graphite is a good lubricant in nature.
It is precisely because of this good physical properties that graphite is used as a wear-resistant copper strip in mold manufacturing industry, and graphite copper sleeve is vigorously applied. Graphite solid inlaid bearing is a high-performance solid lubrication product inlaid with graphite or MoS2 Solid Lubricant on the base of high-strength brass. It breaks through the limitation that the general bearing relies on oil film lubrication.
In the use process, the solid lubricant and the shaft are rubbed by the friction heat, forming the excellent condition of oil and powder coexisting lubrication, which not only protects the shaft from wear, but also makes the solid lubrication characteristic eternal. Its hardness is twice as high as the common copper sleeve, and its wear resistance is also twice as high. At present, it has been widely used in the fields of high temperature, high load, low speed and heavy load, such as continuous casting machine, train support, steel rolling equipment, engineering machinery, mining machinery, mold industry, water conservancy machinery, ships, gas turbines, etc.
