Our Surface Finishing Service includes a full list of standard surface finishes. For custom Surface Finishing Service such as laser cutting or hard anodizing, please contact: info@123.com
Polishing
Polishing is a key Surface Finishing Service that refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the product to obtain a bright and smooth surface. It is the modification of the surface of the product with polishing tools and abrasive particles or other polishing media.
- Applicable Materials
- Texture
- Surface roughness
- Function
- PC, PMMA, Steel, Stainless steel, brass, copper, Aluminum, etc.
- Smooth, glossy finish
- Ra 0.2μm / Ra 32μm
- Reduce product surface roughness, improve product appearance
Anodizing
Anodizing is a high-demand Surface Finishing Service that refers to the electrochemical anodizing of metals or alloys. Under the corresponding electrolyte and specific process conditions, aluminum and its alloys form an oxide film on the aluminum product (anode) due to the action of the applied current.
- Applicable Materials
- Colors
- Thickness
- Function
- Aluminum
- Any RAL code or Pantone number
- 5-20μm
- Make the products not easy to be scratched, not easy to be corroded
Sandblasting
As a core part of our Surface Finishing Service, sandblasting is a critical surface preparation process for metal and plastic parts. It cleans and roughens the substrate surface by the impact of high-speed sand flow. Due to the impact and cutting effect of abrasives, the product surface achieves a uniform matte finish, improving adhesion for subsequent coating and enhancing mechanical properties like fatigue resistance.
- Applicable Materials
- Colors
- Thickness
- Function
- Aluminum, Steel, Stainless Steel, Brass, Copper
- Natural color of raw material
- Uniform matte
- Improve the mechanical properties and fatigue resistance of the product, and increase the service life of the parts
Painting
Painting is a corrosion-resistant coating process in our Surface Finishing Service, which uses corona discharge to ensure powder coatings adhere firmly to metal parts. With a wide range of colors (matching RAL or Pantone codes), it delivers a wear-resistant aesthetic finish that protects components from environmental damage and elevates product appearance.
- Applicable Materials
- Colors
- Thickness
- Function
- Aluminum, Steel, Stainless Steel
- Any RAL code or Pantone number
- 200-300μm
- Improve product appearance. Make products more wear-resistant and corrosion-resistant
Powder Coating
Powder Coating is a high-performance coating process that chemically reacts aluminum with chromate to form a stable chromate film on its surface.This conductive corrosion-resistant coating is ideal for tools, hardware, and electrical systems, delivering long-lasting protection while maintaining electrical conductivity.
- Applicable Materials
- Color
- Applications
- Function
- Aluminum
- Clear, Yellow
- Tools, hardware, electrical systems
- Increase the corrosion resistance of product while maintaining their conductive properties.
Passivation
Passivation is a corrosion-inhibiting surface treatment for steel and stainless steel parts. The metal is oxidized by a strong oxidant or electrochemical method to create an inactive, smooth glossy surface.This process enhances corrosion resistance and extends the service life of precision metal components.
- Applicable Materials
- Colors
- Texture
- Function
- Steel, Stainless Steel
- Natural color of raw material
- Smooth glossy finish
- Make products more corrosion-resistant. Increase the service life of the parts
Zinc Plating
As a key offering in our Surface Finishing Service, Zinc Plating is a rust-preventive surface treatment for steel and stainless steel parts. The part is coated in flux and dipped into molten zinc, which bonds to the steel to create a corrosion-resistant protective layer with a smooth finish. This process is often combined with sandblasting or passivation to enhance durability, making it ideal for hardware and automotive components.
- Applicable Materials
- Texture
- Can be applied with
- Function
- Steel, Stainless Steel
- Smooth finish
- Sandblasting, Passivation
- Prevent product surface oxidation or corrosion
Electropolishing
Electropolishing is a precision electrochemical surface refinement process within our Surface Finishing Service, designed for steel and stainless steel parts. It cleans metallic surfaces, reduces micro-roughness, and removes a thin (up to 10µm) layer of material to achieve a smooth, glossy finish. This process improves surface hygiene and corrosion resistance, making it perfect for medical devices and food processing equipment.
- Applicable Materials
- Texture
- Color
- Function
- Steel, Stainless Steel
- Smooth, glossy finish
- Natural color of raw material
- Improve surface finish
Nickel Plating
Nickel Plating is a wear-resistant electroplating process that deposits a thin, smooth layer of nickel onto aluminum, steel, or stainless steel parts.This corrosion-resistant decorative coating delivers a sleek, polished finish and is often paired with sandblasting or painting for enhanced performance, making it ideal for hardware, automotive parts, and decorative components.
- Applicable Materials
- Texture
- Can be applied with:
- Function
- Aluminum, Steel, Stainless Steel
- Smooth finish
- Sandblasting, Painting
- Make the product resistant to corrosion and abrasion, as well as for decorative purposes
