[PROZESS-FOKUS: GRAPHITE COATING TECHNOLOGY]
Technical Graphite Coatings for Mold Separation
Our heat-resistant bonded graphite coatings cure to form a highly wear-resistant, thermally conductive release film on molds and extrusion dies.

Controlled Coating Thickness and Adhesion
Bonded dry coatings (PROMET GraphCoat) are applied as liquid dispersions and cure thermally to create a resilient carbon structure. The dry, bonded dry film lubrication barrier displays a precise film thickness (10–25 µm) that keeps liquid metal separated from die steel.
This prevents direct alloy erosion on the tools, mitigates thermal shock fatigue, and controls the heat transfer coefficient to guarantee casting solidification without surface defects.
