Product Description

The sintered mould and bracket of the transistor are widely used, which has become an indispensable material for the development of semiconductor industry. And Graphite mould used in cast iron, the durability of various non-ferrous metals with mold, casting mold steel, refractory metals (titanium, zirconium, molybdenum, etc.) with mold and rail aluminothermic welding with welding type of mold, etc. Hot press sintering diamond tools with graphite mould, in the process of manufacturing diamond tools for the heating element and the mold of the dual role of supporting the merits of the quality of graphite mould, precision directly affects the size of the diamond tools, shape, etc. Hot pressing sintering process requirements: (1 to 000 + 2) ℃ temperature is reached, the molding pressure of 16 ~ 50 MPa, heat/pressure time for 15 ~ 30 min, the environment is a vacuum. Under the working condition, requires both molding and graphite mould heating element with electrical conductivity, high resistivity, enough mechanical strength, also need the good oxidation resistance and long service life, in order to ensure that the size of the diamond tool precision and excellent performance. At present, the western developed countries with graphite mould material manufacture diamond tools, mainly for ultrafine grain structure, high purity and high degree of graphitization of graphite materials, its average particle size is less than 15 microns, even under 10 microns, medium pore size is smaller than 2 microns. The graphite mould made of this carbon material has a small porosity, compact structure, high surface finish and strong oxidation resistance, with an average life span of 30 ~ 40 times. The diamond mould requires high hardness, good anti-oxidation performance and high machining precision. The use of high quality graphite materials greatly extends the service life of the mould and improves the anti-oxidation performance.
