China Mould Mold Graphite Mould

Graphite mould for diamond tool
L.T Grouphas a comprehensive product and technology portfolio that focuses on four fields of graphite- ultrafine particle graphitemould, graphiteelectrode, graphite crucible, as well as other products mainly made of graphite. Graphitematerials exhibit unique properties such as good electrical and thermal conductiHydraulic Tool vity, 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 graphiteare in increasingly high demand in industries. They also play a progressively important role in everyday life, thereby substituting traditional materials.
Graphite mould plays adual 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: DurableOur 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 durable
1.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 accuracy
3.Good conductivity, high resistivity, sufficient mechanical strength
4.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.
1. 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. Electronics Stocks 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 assembliInstruments & Meters ng different parts into awhole graphite mold.During the assembling period, unqualified products will be picked ouElectronic Instrument t.
