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
As an important current-receiving component directly in contact with the main line catenary, the receiving carbon slide plate is installed on the uppermost part of the receiving grid. Our company mainly supplies two kinds of carbon skateboards:
1) Pure carbon graphite skateboard
Use a certain proportion of pitch coke, petroleum coke, graphite powder, carbon black or hard carbon to mix with each other, press and shape it first, and then put it into a high-temperature sintering furnace for roasting. The product can be used on the bow after reprocessing.
2) Copper-impregnated carbon skateboard
This type of slide not only combines the characteristics of high mechanical strength and low resistance of powder metallurgy slides, but also combines the self-lubricating ability of pure carbon slides and the characteristics of less wear on overhead contact nets.
Application:
The main function of the pantograph is to obtain power from the rated voltage DC1500V catenary to supply power to the entire train electrical system. At the same time, the regenerative braking system of the train converts the kinetic energy of the train into electrical energy and feeds it back to the catenary for other online trains. to the role of a two-way transfer hub. The pantograph can be applied to both rigid catenary and flexible catenary lines. In the entire vehicle speed range, the pantograph has good dynamic characteristics, which can ensure good contact with the catenary under various tracks and speeds. Contact state and contact stability.
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.
