Hot Press

Hot Press

Possessing excellent thermal durability, chemical resistance, and thermal shock resistance, graphite is an ideal material for hot press components under harsh usage condition.


There is a great variety of hot press equipment designed for different temperatures, pressures, atmospheres, and molded products.

Isotropic graphite--which has excellent thermal durability, chemical resistance, and thermal shock resistance--can be used under extremely harsh conditions (high-temperature environments in excess of around 1000°C) that other heat-resistant alloys and similar materials are incapable of withstanding. As such, it is used in major components for hot press equipment (including dies, punches, and heaters).

Compared to other heat-resistant alloys and ceramics, isotropic graphite offers good workability, which allows it to be used in large-scale designs.

In addition, Toyo Tanso's high-strength C/C composites are used in dies capable of withstanding high-pressure molding, while our graphite sheets (PERMA-FOIL®) with heat-spreading and mold-release propertiesare widely used as a mold facing in powder metallurgy and ceramics manufacturing processes.。
