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 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:
- Good performance on conductivity and high rate resistivity
- Enough Mechanical Strength
- Good performance on Oxidation resistance
- Durable
Why choose us:
Raw materials is very important, We only use Ultrafine particle structure,
High purity and High graphitization raw graphite materials.
Our finished graphite mold is:
- dense structure and low porosity
- Fined surface and low rate heat-deformation
- High mechanical strength and machining accuracy
- Oxidation resistance and durable
C: Product features
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.
D: Processing method
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. 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.
