The Graphite Sintering Mold materials used in diamond tool manufacturing are mainly graphite materials with ultra-fine particle structure, high purity and high degree of graphitization. The average diameter of graphite mold material is less than 15 microns, or even less than 10 microns, and the average pore diameter is less than 2 microns. The graphite mould made of the carbon material has the advantages of small porosity, compact structure, high surface finish, strong oxidation resistance, etc. The average service life can reach 30 ~ 40 times.
Electron sintered graphite molds and transistor supports can be made from artificial graphite materials with minimal thermal deformation. At present, they are widely used and have become indispensable materials for the development of semiconductor industry.
The electronic sintered graphite mould of hot-pressed sintered diamond cutter has double functions of heating element and die support in the manufacturing process of diamond cutter. The quality of graphite mould directly depends on the size accuracy and appearance shape of diamond cutter.
a container used for melting and casting non-ferrous, non-iron metals such as gold, silver, aluminum, and brass. The main reason graphite crucibles are popular as a manufacturing tool is their thermal conductivity, high temperature resistance, small thermal expansion coefficient for high temperature applications, and their anti strain properties to rapid heating and cooling. They are corrosion resistant to acids and alkaline solutions and have excellent chemical stability.
Graphite can be produced from natural graphite that is a naturally occurring crystalline form of carbon. This form of graphite is manufactured by combining graphite with fire resistant clay or carbon dioxide.
Synthetic graphite is produced by processing petroleum pitch and petroleum coke, which are byproducts of the oil refining process. It has a purer high fixed carbon content with very few impurities and a low sulphur content.
Types of graphite pipes:
There are two types of one type is machined graphite pipes from raw block graphite material. graphite materials can be: Isostatic graphite, Molded graphite, Extruded graphite, Vibration graphite, mechanical graphite and carbon brush materials. Another type of graphite pipe is resin extruded graphite pipes, with powder and graphite powder mixed together, then graphitized in high temperature. this type of graphite pipes is mainly used for heat exchangers, and can be with bigger length compared to the first type. It can reach a length of 6-7meters.
Machined graphite pipes is produced from graphite material, so it has the characteristics of graphite material.
Graphite and its products with high strength and acid resistance, corrosion resistance and high temperature 3000 ℃ and low temperature -204 ℃ and other fine features, are widely used in metallurgy, chemical, petrochemical, high-energy physics, aerospace, electronics and so on.
Extruded resin graphite pipes: this type of graphite pipe is with resin powder and graphite powder mixed together, then graphitized in high temperature. This type of graphite pipes is mainly used in heat exchangers, and can be with bigger length compared to the first type. it can reach a length of 6-7meters. but the diameter is not big.
Resin mainly refers to the phenolic resin extrusion of graphite tube. This graphite tube has the characteristics of graphite, and it has the characteristics of phenolic resin, so it is a perfect combination. It has excellent corrosion resistance and good thermal conductivity.This graphite tubes is mainly used in tube type graphite heat exchanger. In many corrosive materials under the conditions of heat transfer is widely used. The graphite tubes that CFCCARBON LTD produced is with 300 C heat treatment, its thermal conductivity is about 30-40w / (m.k), much higher than other non-metallic anti-corrosive materials, and higher than the stainless steel. Therefore, graphite resin tube has long been quietly step into hydrochloric acid, chlor-alkali industry, and into the chemical industry, pharmaceutical, metallurgy, electroplating, printing and dyeing, paper, environmental protection and other industries.
are typically made from metals such as cast iron, ductile iron, steel or aluminum. Ingot molds are used for casting refined metal such as aluminum, copper, lead and zinc into various shapes and sizes for future processing.
An ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing.
If you need cast iron, ductile iron, steel or aluminum ingot molds for your smelting operation, Dynaform Technologies is your best choice. Possessing an extensive range of metalworking molds, our experts will provide you with the right mold for your needs, regardless of the metal you are working with.
