After the initial processing, the metal surface needs to be modified to beautify the metal surface, improve the mechanical properties,physical and chemical properties. The metal surface are further changed. This is called metal surface treatment, or metal surface processing.
Purpose of Surface Treatment
- Improve appearance
- Protection( Anti-oxidazation,wear, Anti-chemical etc)
-special surface properties
-mechanical or engineering property
Types of surface treatment
- Mechanical method :bead strike method, cutting, honing, sand blasting, fine grinding, grinding, super processing.
- Metallurgical method : surface hardening, (quenching, carburizing,nitriding), diffusion film method. - Chemical method
- electrolytic grinding, pickling, chemical grinding, acid etching.
Surface finish compatiable for different Manufacturing Technology
Surface Treatment Rich offer
Anodizing
It is a finish that protects metal by increasing the surface oxide layer. it is used to improve durability and enhance corrosion resistance. Anodize process can provide various colors and improve wear resistance. It provide better adhesion for painting and reduces galling of threaded components.
Application Matetial: Aluminum parts
Standard colors offered include: black, blue, red, gold and non-dyed.
Powder Coating
Powder coating looks similar to paint but is more durable.
Powder coating is a process that “bakes” powdered plastic onto a metal surface. The coating is relatively hard and abrasion resistant. Powder coating adds typically 60-90 μ to each coated side and edge. Textured powder is less susceptible to imperfections than matte or glossy.
Application: Steel, Aluminum
Color: custom any color as per the Pantone color code
Electroplating
Electroplating is a metal finishing process used to finish your part surface by submersing the part in a tank of chemicals and applying an electric current.
Plating Type: Zinc plating, Chrome Plating, Gold/Silver/Nickel Plating, Brass/Copper Plating
Applications: Electroplating can be used to prevent corrosion, increase mechanical durability, alter surface friction or improve appearance.
Plating is often often used on parts made of Aluminum, Copper, Steel and Brass.Properties Electroplating does not substantially hide or smooth surface imperfections.
Sanding And Polishing
Reach Meal offer the most professional finishing service for youetal ototype and production needs. This often involves fine hand sanding in a variety of grits to prepare your parts for later painting and plating.Sanding is not just used for painting prep but to create the final surface finish. We can provide brushed and satin surfaces for a variety of metallic effect.
Blasting
involves the controlled spraying of an abrasive media against the surface of your part.
Blasting is to clean and deburr parts, preparing them both for Plating, Anodize ,powder coating
