During the calcinating process, the physical and chemical properties of raw materials are increased.
Kneaded material is formed using an extrusion press.
Through the baking process, the thermal stability, mechanical strength and electrical conductivity of materials can be greatly improved.
The baked electrodes are impregnated with a special pitch to give them the higher density, mechanical strength, and electrical conductivity to withstand the severe operating conditions inside the furnaces.
Processing the baked material at extremely high temperatures to change its structure from amorphous carbon to graphite and obtain excellent material properties.
Machining the graphitized material to achieve the required size, shape and accuracy, to make the electrode body and pin according to the specification of customers.
