Surface Finishing Services for Custom Parts
Whether metal or plastic, from one-off prototypes to full-scale mass production, whether CNC machining, polyurethane casting, injection molding or 3D printed parts, custom parts must undergo a rigorous surface treatment process in order to obtain the exact look of the end product, The process describes the final steps required before the product actually becomes a reality. Alter the surface of custom parts using different techniques to improve appearance and performance. These include corrosion resistance, discoloration resistance, chemical resistance, abrasion resistance, hardness, changing electrical conductivity, and deburring or applying specific colors to parts.

Xinyi Technology’s finishing services include hand machining, sanding, sandblasting, polishing, painting and printing, laser etching, anodizing, black anodizing, powder coating, metal plating, vacuum metallization, chromating, chemical surface treatments , passivation, heat treatment, etc.
Painting：
We use the Pantone matching system and the RAL classic system to match custom colors or paint samples. We can also do two-color or multi-color painting for a more intricate look that looks like a 2K injection molded part.
Paint Finish:
We can offer different paint finishes including matt, flat, semi-gloss, gloss or satin. We can also simulate specific Mold-Tech textures or soft touch for a textured or overmolded feel similar to injection molded parts.
Functional coating:
UV coatings resist ultraviolet radiation and protect the underlying material for enhanced durability and resistance to abrasion or scratches. For EMI, coatings are used to shield or contain electronic equipment from magnetic fields or interference.
Anodizing：
contributes to the corrosion resistance of aluminum parts, increases surface hardness, and improves wear resistance. The process is both functional and aesthetic. There are two main types of anodizing:
Type II anodizing：
is primarily used to produce parts with a uniform, aesthetically pleasing surface and offers good corrosion resistance with limited wear resistance and is available in a variety of color dye options. Typical coating thickness: black 12-18μm, transparent 8-12μm, color 4-8μm.
Type III anodizing：
also known as hard anodizing, has excellent corrosion and abrasion resistance and is suitable for functional applications, but is more limited in color, usually only clear or black. Typical thickness is 30-125μm.
Vacuum metal coating
Vacuum metallization is a form of physical vapor deposition (PVD), the process of bonding metals to non-metallic substrates by evaporation. Layer thicknesses are typically a few micrometers and various surface treatments are possible. The metal most commonly used in vacuum metallization is aluminum for a number of reasons, including cost, thermodynamics, and reflective properties.
Plating
Electroplating is a metal surface treatment that involves applying a very thin layer of another metal or metal alloy to a metal part to prevent corrosion and oxidation of the underlying part, or to alter its appearance. Tin, nickel, zinc (galvanized) and chromium are common plating metals.
Powder Coating
Powder coating adds a thin layer of protective polymer to the surface of a part. It uses the phenomenon of corona discharge to cause the powder coating to adhere to the workpiece, resulting in a strong, wear-resistant finish. Typical thicknesses vary from approximately 50 μm to 150 μm.
Printing and Etching
Powder coating adds a thin layer of protective polymer to the surface of a part. It uses the phenomenon of corona discharge to cause the powder coating to adhere to the workpiece, resulting in a strong, wear-resistant finish. Typical thicknesses vary from approximately 50 μm to 150 μm.
