Influence of graphite mould on quality of diamond tool head.
1. In the process of hot pressing, the temperature, the size of the pressure, the length of the insulation time, and the loss of matrix materials are one of the four key factors affecting the quality of the blade.
2 graphite mould at high temperature, instead of down will not only improve mechanical strength, chemical stability strong, conductive thermal conductivity is good, therefore, in the synthetic diamond tools and products in the industry, bit and saw blade hot-pressing sintering, are graphite is used to make mold
3 graphite mould in sintering for the heating element and the mold of the dual role of supporting our company adopts high purity, high density of graphite mould, graphite raw material processing can improve the cutting performance and service life of the cutting tools
3.1 volume density should be greater than 1.75g/cm 3.
3.2 the smaller the porosity of graphite opening, the better, generally less than 13%.
Provide us with pictures and detailed physical and chemical indicators, we can make all kinds of high strength graphite moulds according to your requirements, and welcome friends at home and abroad to select and order.
The following schedule is the main specifications of our graphite produces. If you have other requirements welcome the email details.
Main products: high purity graphite,Isostatic pressed graphite, graphite electrode, flake graphite, , mechanical equipment , various processing graphite mould and graphite products.
