Surface Finishing Services
From functional protection to premium aesthetics, QSY offers custom surface finishing solutions for CNC machined, sheet metal, and molded parts. Our finishing processes help improve surface quality, durability, and product performance with consistent results.
Polishing
Polishing 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:
PC, PMMA, Steel, Stainless steel, brass, copper, Aluminum, etc
Texture:
Smooth, glossy finish
Surface roughness:
Ra 0.2μm / Ra 32μm
Function:
Reduce product surface roughness, improve product appearance
Anodizing
Anodizing 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:
Aluminum
Colors:
Any RAL code or Pantone number
Thickness:
5-20μm
Function:
Make the products not easy to be scratched, not easy to be corroded
Sandblasting
Sandblasting is the process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Due to the impact and cutting effect of abrasives on the surface of the product, the surface of the product can obtain a certain degree of cleanliness and different roughness.
Applicable Materials:
Aluminum, Steel, Stainless Steel, Brass, Copper
Colors:
Natural color of raw material
Texture:
Uniform matte
Function:
Improve the mechanical properties and fatigue resistance of the product, and increase the service life of the parts
Spray Painting
Spray painting is a surface coating process for industrial products. Liquid paint is atomized and evenly sprayed onto workpiece surfaces, then cured to form a protective and decorative coating.
Applicable Materials:
Various types of materials such as plastic, metal, and wood.
Colors:
Can be customized to any color
Application scenarios:
Electronic product casings, automotive components, household appliances, toys, hardware parts, etc.
Function:
Beautify appearance, prevent scratches and wear, resist corrosion, enhance product durability
Powder Coating
It refers to the treatment method of chemically reacting metal with chromate to form a stable chromate film on its surface.
Applicable Materials:
Aluminum
Colors:
Clear, Yellow
Applications:
Tools, hardware, electrical systems
Function:
Increase the corrosion resistance of product while maintaining their conductive properties.
Passivation
Passivation refers to the process in which the metal is oxidized by a strong oxidant or electrochemical method to make the surface into an inactive state.
Applicable Materials:
Steel, Stainless Steel
Colors:
Natural color of raw material
Texture:
Smooth glossy finish
Function:
Make products more corrosion-resistant. Increase the service life of the parts
Zinc Plating
This process is done by coating the part in a flux and dipping the part into molten zinc. The molten zinc forms a bond with the steel, creating a protective layer on the surface of the part.
Applicable Materials:
Steel, Stainless Steel
Texture:
Smooth finish
Can be applied with:
Sandblasting, Passivation
Function:
Prevent product surface oxidation or corrosion
Nickel Plating
Nickel plating is a process used to electroplate a thin layer of nickel onto a metal part.
Applicable Materials:
Aluminum, Steel, Stainless Steel
Texture:
Smooth finish
Can be applied with:
Sandblasting, Painting
Function:
Make the product resistant to corrosion and abrasion, as well as for decorative purposes
Electropolishing
Electropolishing is an electrochemical process used to clean metallic surfaces and reduce micro-roughness of stainless steel parts. Useful to remove a thin (up to 10μm) layer of material.
Applicable Materials:
Steel, Stainless Steel
Texture:
Smooth, glossy finish
Colors:
Natural color of raw material
Function:
Improve surface finish
