HOTPLUS coating series, which provides solutions in hot work applications; It is especially preferred in applications where high oxidation/degradation resistance is expected from coatings.
- High Pressure Metal Injection (zamak, aluminum, magnesium)
In metal injection molds, hotplus series PVD coatings can prevent and solve erosion, wrapping/adhesion damages that may occur on the surfaces of the mold and mold components (core, insert, pin, etc.). In addition, the formation of thermal fatigue cracks with a capillary and reticulated appearance on the steel surface can be postponed.
- Metal Extrusion (aluminum, brass, copper, silver)
With hotplus series PVD coatings in extrusion molds, a solution is provided by increasing the hot wear resistance on the mold surfaces and preventing wear damage.
- Hot forged
Hot plus fexoy coating in hot forging press molds increases hot abrasion and collapse/crushing resistance, thus preventing abrasion damage that determines mold life.
- Hot Forming
Hotplus series PVD coatings can especially prevent and solve wrapping/plastering/adhesion damage in hot forming molds.

FEXOY Coating
It is a coating with high wear resistance (crater wear) and lubricity properties obtained by applying a combination of diffusion process hardening and oxide-based coating. FEXOY coating gives very good results especially in hot forging press molds and high pressure metal injection sleeves where it is applied together with our surface preparation solutions.
