PVD vacuum deposition service CERTESS® EJECT

PACVD

EJECT stacks are coatings developed for plastic and aluminum forming tools to guarantee very low wear in the injection zone and easy demolding for a wide range of materials. The aim is to increase tool life, improve the quality of parts produced, reduce lubrication, cut tool maintenance and reuse tools. Features : - Hardness from 2000 to 6000 HV - Abrasive and adhesive wear resistance - Chemically inert - Thermal stability up to 800°C - Oxidation resistance Treatable materials: - Steels and cast irons - Inconels - Aluminum, copper and titanium alloys Application examples: - Punches - Dies - Cavities - Mold peripherals - Ejectors - Slides They enable coatings to be obtained with : - Thicknesses ranging from a few nanometers to tens of microns - Hardnesses ranging from 1000 to 4000Hv Depending on the coating chosen, they provide treated parts with : Tribological: very low coefficient of friction Mechanical: very high hardness Electromagnetic shielding Optical Electrical conductivity Antibacterial Decorative... This process is implemented in a vacuum chamber where a plasma is created. The HEF group mainly uses 3 methods to generate its plasmas and produce high-quality layers: PEMS™ CAM™ M-ARC™.
