Graphite Solutions for Tomorrow's Innovations
Molded graphite has outstanding performances in mechanical strength, abrasion resistance, density, hardness and electrical conductivity and these performances can be further improved by impregnating resin or metal.
Molded graphite features good electrical conductivity, high temperature resistance, corrosion resistance, high purity, self-lubrication, thermal shock resistance and easy precision machining, and is widely used in the fields of continuous casting, hard alloy and electronic die sintering, electric spark, mechanical seal, etc.

The molding method is generally used to produce small-sized cold-pressed graphite or finely structured products. The principle is to fill a certain amount of paste into a mold of the required shape and size, and then apply pressure from the top or bottom. Sometimes, apply pressure from both directions to compress the paste into shape in the mold. The pressed semi-finished product is then demolded, cooled, inspected, and stacked.
There are both vertical and horizontal molding machines. Molding method generally can only press one product at a time, so it has a relatively low production efficiency. However, it can produce high-precision products that cannot be made by other technologies. Moreover, the production efficiency can be improved through simultaneous pressing of multiple molds and automated production lines.
