Graphite Hot Pressing Molds

SIKAIDA Graphite Hot Pressing Molds use high-quality, high-purity graphite as the main raw material and are widely applicable to hot pressing processes for various powder metallurgy and ceramic materials. Custom designs can be made according to product shape and size requirements.

Graphite Hot Pressing Molds exhibit excellent high-temperature resistance, operating stably at temperatures up to 2000℃, with continuous operating temperatures up to 1800℃. They do not deform or react adversely with reactive materials during hot pressing. The surface undergoes special treatment, resulting in high smoothness and precise dimensional control, effectively reducing product defect rates. Simultaneously, the excellent thermal conductivity of graphite ensures uniform temperature distribution, improving product sintering quality and production efficiency.
