Product Description
China Graphite Supplier Graphite Molds for Casting Metal
Graphite mold is an allotrope of elemental carbon. The periphery of each carbon atom is connected with three other carbon atoms by covalent bonds to form covalent molecules. Since each carbon atom emits an electron, those electrons can move freely, so graphite belongs to a conductor.
The graphite mold has good chemical stability. Specially processed graphite has the characteristics of corrosion resistance, good thermal conductivity, and low permeability. It is widely used in the manufacture of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters , Pump equipment. It is widely used in petrochemical industry, hydrometallurgy, acid-base production, synthetic fiber, papermaking and other industrial sectors, which can save a lot of metal materials.
Graphite molds are used for casting, sand turning, compression molding and high-temperature metallurgical materials: due to the small thermal expansion coefficient of graphite and resistance to rapid cooling and rapid heat changes, it can be used as a casting mold for glassware. After using graphite, the ferrous metal can obtain accurate casting size and surface finish rate High, can be used without processing or a little processing, thus saving a lot of metal. Production of powder metallurgy processes such as cemented carbide, usually using graphite materials to make ceramic boats for stamping and sintering. Single crystal silicon crystal growth crucibles, area refining vessels, support fixtures, induction heaters, etc. are all made of high-purity graphite. In addition, graphite can also be used as a vacuum smelting graphite insulation board and base, high temperature resistance furnace tube, rod, plate, grid and other components.
Six excellent properties of graphite mold:
1. Excellent thermal and electrical conductivity
2. Very good thermal stability and resistance to heating shock due to low linear expansion coefficient
3. Resistant to chemical corrosion and multi-metals are not easy to react
4. At high temperature (in the sintering temperature of most copper-based carcass above 800℃), the strength increases with increasing temperature
5. Has good lubrication and wear resistance
6. It is easy to process and has good mechanical processing performance. It can be made into a mold with complex shape and high precision.
Nowadays, graphite mold design has been transformed from artificial experience design to relying on computer-aided design. Modern graphite mold enterprises all widely use computer-aided technology and artificial intelligence technology to make decisions. Simulation analysis and optimization design. At the same time, the application of database and computer network technology allows designers to share design information, information, resources and cooperation on a larger scale, so that the overall level of modern graphite mold design has risen to an unprecedented height.
