Graphite Sintering Molds: Core Tool for Diamond and Cemented Carbide Sintering

Graphite sintering molds excel in high-temperature manufacturing, with advantages perfectly matching the needs of precision sintering. They feature exceptional heat resistance, maintaining stability at over 2000°C—critical for consistent results in high-heat sintering processes. Their excellent thermal conductivity ensures uniform heat distribution, avoiding material deformation caused by temperature differences. Additionally, they have strong wear resistance, which greatly reduces the frequency of mold replacement and cuts production costs.​

In terms of applications, they are indispensable in diamond sintering and cemented carbide sintering. For diamond sintering, these molds create a sealed, high-temperature environment to bond diamond grains with metal binders, ensuring the final diamond tools (such as cutting blades and grinding wheels) have high hardness and wear resistance. In cemented carbide sintering, they precisely shape carbide powder mixtures (like tungsten carbide and cobalt) into components—including mining drill bits and machine tool cutters—preserving the material’s structural integrity and mechanical performance during the sintering process.​
