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 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.
Application:
Graphite tubes/poles have a wide application fields, such as:
a.Used in furnaces because of graphite's low heat sensitivity
b.Used for Aluminum degassing
c.Used in the production of fluxing tubes used in the metal manufacturing industry
d.Other industries using graphite tubes include chemical and scientific industry
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.
