Product Description

sintering graphite star-segment design mold for diamond grinding wheel lttrade.en.made-in-china.com

A: Company profile L.T Group has a comprehensive product and technology portfolio that focuses on four fields of graphite - ultrafine particle graphite mould, graphite electrode, graphite crucible, as well as other 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 maintaining high strength. Due to the shortage of energy and raw materials, our high performance products made from graphite are in increasingly high demand in industries. They also play a progressively important 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 element and Supporting mold.The quality of graphite mold is very important, will directly affect the next diamond tools' accuracy and appearance.So, which kind of graphite mold is suitable for sintering diamond 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 High graphitization 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 high graphitization 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 parts if 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 the assembling period, unqualified products will be picked out.E: Tech Data
