In order to increase the corrosion resistance of the parts, the conductivity or to improve the appearance, ETMA is capable of performing the following surface treatments:
• Electrolytics with deposition of: Zinc, Zinc-Nickel, Nickel, Copper, Silver, Tin
• Chemicals for: phosphatising and oxidation
• Dipping / Spin: Zinc flake coating, top coats and sealants
• Dehydrogenation: performed in all parts of medium and high carbon
• Degreasing / Wash: in closed chamber with perchloroethylene fulfilling European standards
• Deburring / Polishing with abrasives: ceramic and porcelain

TECHNICAL TEAM

• Our team has expertise and proper technical training adapted to the needs of this special process, making measurement of thickness, corrosion resistance and adhesion

RAW MATERIALS
