CNC Machined Parts
Finishing processes are done by approved vendors and suppliers only, GTA does not do these processes in-house
To improve the appearance of the metal, a number of finishing techniques can be used, Anodizing, Silk screening, E-coating, powder coating and plating, Benefit to these processes are, clean and smooth surface, glossy, or matte and give metals to a decorative finish,
Metal Finishing provides ease of cleaning. Contamination and adhesion are reduced due to the incredible smoothness of the metal surface. Most non stick pans are anodized.
Metal finishing makes metal more durable, prevents rust, wear and resistance to abrasion. Metal finishing also increases longevity of the product
Anodizing is an electrochemical process, it adds thin layer of anodic (oxide) to metal, it can increase wear , tear and corrosion resistance of the metal, Anodizing can be dyed with lot of colors. Mostly this process is used on Aluminum.
Alodine is a trademark name, Alodine is chemical conversion film used on aluminum to protect from corrosion, Alodine coating turns aluminum into light yellow color, Alodine is also known as chemical conversion coating, Alodine Film is very thin and does not change part dimension.
CVD and PVD Coating
Black oxide is a conversion coating produced by a chemical reaction, Black oxide is cheaper solutions than chemical conversions. Oxide is very thin coating, does not change the dimensions of the part, Black oxide adds a layer of corrosion,abrasion resistance and improves lubrication. Oxide will not chip, flake or peel off. Most commonly used on bolts, nuts, drills, Pulleys etc.
