Company profile
L.T Group has a comprehensive product and technology portfolio
that focuses on four field
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.
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.
