A: Company profile
As a proud subsidiary of L.T Group, L.T Graphite with four producing bases located at middle of China, Henan province, and a branch producing base at Sichuan province. L.T graphite covers the entire value chain of fine and medium grain graphite production. From raw material selection, semi-finished product manufacture, precision machining, impregnation, purification, and coating. This is how we ensure the consistent high quality and performance of our products.
B: Why choose us
Medium particle special graphite producing base:
Founded in 1995, with three complete production lines from raw materials to calcination to graphitization, this facility is an independent innovation base integrating R & D, production and processing. We have strong machining capabilities, can process all kinds of shaped graphite parts according to customers' needs. With independent research and development center, complete testing equipment, our this base has passed ISO9001 quality management system certification and ISO14001 environmental management certification.
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.
