Our Surface Finishing Capabilities
Use HLH as your one-stop solution for both manufacturing and surface finishing of your custom parts, reducing the risk of production. Here is a list of standard surface finishes. For custom surface finishes such as laser cutting or hard anodizing, please contact: info@qsymodel.com
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.
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 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.
Aluminum
Any RAL code or Pantone number
5-20μm
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.
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
This is a coating process that uses corona discharge to make powder coatings adhere to the product. A wide variety of colors are available to create the desired aesthetic.
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
It refers to the treatment method of chemically reacting metal with chromate to form a stable chromate film on its surface.
Aluminum
Clear, Yellow
Tools, hardware, electrical systems
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.
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
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.
Steel, Stainless Steel
Smooth finish
Sandblasting, Passivation
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
Smooth finish
Sandblasting, Painting
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.
Steel, Stainless Steel
Smooth, glossy finish
Natural color of raw material
Improve surface finish
