A: company
profile
L.T
Graphite 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 cutting sheet 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:
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:
C: Product

D:
Processing method
1.
Customer provide design drawings.
2.
Dividing machine will separate big graphite blocks to suitable
small blocks, then the suitable small blocks will turn to
Automatic lathe grinding to raw cylindrical products, and cut to
graphite discs. We will strictly keep the thickness deviation
within ±0.02-±0.1mm, diameter deviation within
±0.03-±0.1mm.
3. Our
tech-workers will design the cutting process and drawings. The
qualified graphite discs will turn to Automatic milling machine
processing and forming. We will checking each piece of finished
products and sure the slotting deviation within ±0.01-0.06mm,
slotting shape deviation within
0.02-0.04mm.
