Description
Isostatic Graphite for Diamond Sintering Molds
SHJ Graphite's advanced technology isostatic graphite have demonstrated excellent performance in the sintering process of powder metallurgy diamond tips.
Graphite has a wide range of applications in powder metallurgy. Graphite sintering molds play an important role, especially in manufacturing diamond alloy materials and cemented carbide materials. With the rapid development of geological exploration, coal and oil exploration and mining, highway cutting, as well as granite and marble mining and cutting and other industries, the demand for diamond alloy materials and tungsten carbide materials has risen sharply, which in turn has driven the growth in the demand for graphite sintering dies.
Isostatic Graphite Used for Diamond Sintering Molds
Graphite is an indispensable material for manufacturing diamond sintering molds. In the production process, graphite molds are consumed quite a lot, and their performance directly affects the quality and production cost of sintered or hot press molded diamond tool products.
SHJ graphite has excellent electrical and thermal conductivity, does not react easily with most molten metals, and does not deform at high temperatures. As the temperature rises, graphite's electrical and thermal conductivity and strength increase significantly.
In addition, graphite's coefficient of thermal expansion is lower than that of metals, which ensures the dimensional stability required for diamond molds, and is therefore widely used in the powder sintering industry. This makes it an ideal material for the production of diamond tools (e.g. diamond drills, blades, etc.).
