PLEASE NOTE: All the material are high purity graphite and fine-grain, as a graphite manufacturer who can provide stable supply for big customer, we have uniform shaped graphite rods and graphite blocks in stock all the time.
The molding method is to load a certain amount of paste into a mold having a desired shape and size and then press it from the upper or lower portion. Sometimes, a certain pressure is applied to the paste from both the upper and lower directions, so that the paste is compressed and formed in the mold. The pressed semi-finished product is then inspected by demoulding cooling. Then pile it up. Molding equipment has vertical presses and horizontal presses. Molding method generally only presses one product at a time, and the production efficiency is relatively low. But it can make products that cannot be made by some extrusion methods. Molded graphite has a wide range of properties in terms of mechanical strength, abrasion resistance, density, hardness, electrical conductivity, etc., and can be further improved by impregnating a resin or a metal.
