Product Description Graphite mould for hot - pressed diamond geological bit lttrade.en.made-in-china.comA: Company profile L.T Group has a comprehensive product and technology portfolio that focuses on four fieldof graphite - ultrafine particle graphite mould, graphite electrode, graphite crucible, as well asother products mainly made of graphite. Graphite materials exhibit unique properties such as good electrical and thermal conductivity,heat and corrosion resistance, low friction, and reduced weight while at the same time maintaininghigh strength. Due to the shortage of energy and raw materials, our high performance productsmade from graphite are in increasingly high demand in industries. They also play a progressivelyimportant role in everyday life, thereby substituting traditional materials.B: Why choose us Graphite mould plays a dual role in the process of diamond tools manufacture:Heating elementand Supporting mold.The quality of graphite mold is very important, will directly affect the nextdiamond tools' accuracy and appearance.So, which kind of graphite mold is suitable for sinteringdiamond tools: a: Good performance on conductivity and high rate resistivity b: Enough Mechanical Strength c: Good performance on Oxidation resistance d: Durable Our mold features:Raw materials is very important, We only use Ultrafine particle structure, High purity and Highgraphitization raw graphite materials.Our finished graphite mold is: a: dense structure and low porosity b: Fined surface and low rate heat-deformation c: High mechanical strength and machining accuracy d: Oxidation resistance and durableC: Product features1.The processing materials are ultrafine granule structure, high purity and graphite with highgraphitization degree.2.High hardness, good anti-oxidation performance and high machining accuracy3.Good conductivity, high resistivity, sufficient mechanical strength4.Small porosity and dense structure.5.Excellent thermal shock resistance, conductive and thermal conductivity.6.High temperature resistance, corrosion resistance, acid and alkali resistance, good wear resistance.7.Surface can be treated with anti-oxidation.D: Processing method1. Customer provide design drawings.2. Our technical team will check, analyze the drawings, and divide the drawing to reasonable partsif needed, and prepare proper graphite blocks .Our mechanics will design and customize grinding wheel.3. Our workers will grinding and polishing graphite block according to the instructions of mechanics.This process may need operating few times if needed.We will strictly keep deviation within ±0.03-0.08mm.4. Then our packing team will assembling different parts into a whole graphite mold.During theassembling period, unqualified products will be picked out.E: Manufacturing a sintering mouldA WELL-CONTROLLED COEFFICIENT OF THERMAL EXPANSIONUnderstanding changes in the coefficient of thermal expansion is very important when designing a sintering mould. Our grades have been studied over a wide range of temperatures and offer remarkable stability.A SELECTION OF GRADES ACCORDING TO APPLICATIONSThe material used to manufacture a graphite mould is selected based on the process temperature and pressure requirements. Some of our grades are selected when the material's electrical and thermal conductivity are the prioritised parameters in order to reduce cycle time. When the process pressure is too high, the mechanical strength of the mould is prioritised. Our experts are at your disposal to discuss the best grades adapted to your specific needs.DescriptionLT-4LT-5LT-7LT-8Bulk Density g/cm31.81.851.851.91Electrical Resistivity uΩ·m10-128.5-1011-1311-13Flexural Strength MPa 43465160Compressive Strength MPa 8085115135Thermal Conductivity W/m*K110139.28585Temperature resistance oC4350435043504350Ash content %0.030.030.030.03
