EUSurface Finishes
Surface treatment is a technological method to artificially form a surface layer on the surface of the product material with mechanical, physical, and chemical properties different from that of the matrix.

Descriptions
Alodine
Copper,
Magnesium
Yellow
Alodine is a chemical coating. Used to passivate and protect the workpiece from corrosion. Alodine is widely used in chemical industries such as electroplating, welding, alloy manufacturing, pigments, and leather making.
Anodizing
Aluminum, Titanium, Magnesium
Clear, Yellow,
Green, Blue,
Black, Orange,
Purple, Red
Anodizing is an electrochemical process that converts the aluminum surface into a hard, durable oxide layer. It improves corrosion resistance, wear resistance, and allows dyeing in multiple colors. Anodizing is widely used in aerospace, consumer electronics, automotive, and medical device industries.
Painting
All Materials
Clear, Yellow,
Green, Blue,
Black, Orange,
Purple, Red
Fix the product to be sprayed on the rotating bracket, and then lock the bracket on the assembly line. Spray the paint evenly on the surface of the product. It gives a good touch feel onto the product, but is easy to scratch.
Black Oxide
All Materials
Black
Black oxide is also an oxide film. Mainly used to increase the corrosion resistance and appearance of the product, and to minimize light reflection. Suitable for surface treatment of steel and stainless steel products.
Brushing
ABS, Aluminum, Brass, Stainless Steel, Steel
N/A
Brushing is a surface treatment method that forms lines on the surface of the workpiece by grinding the product to achieve a decorative effect. Make the product more beautiful.
Chrome-Plating
Aluminum, Stainless Steel, Steel, Brass, Copper
Chrome
As a type of electroplating technique, chrome plating processes a thin layer of chromium onto a plastic or metal surface. This layer can be decorative, corrosion-resistant, and increase surface hardness.
Laser engraving
All materials
Chrome
Both laser engraving and etching uses high heat from the laser beam to leave a permanent marking on the plastic part surface. The engraving creates deep marks by removing the material, whereas the etching is using high heat to melt the material.
Nickel Plating
Aluminum, Stainless Steel, Steel, Brass, Copper
N/A
Nickel plating is the process of depositing nickel on the surface of metal parts. It can effectively improve the surface gloss, corrosion resistance, and abrasion resistance of the product.
Pad printing
PC, Nylon,
PE, PET
N/A
Similar to silk screening, pad printing is an indirect offset printing process, A curved pad made of silicone rubber is dipped into the surface of the pad and pressed onto the desired surface to print words, patterns, etc.
Passivation
Aluminum, Stainless Steel, Steel
N/A
Passivation is a chemical reaction. It can delay the corrosion rate of metal materials and effectively increase the service life of the product.
Powder Coating
All Metal Materials
Can be Customized
Powder coating is a process of applying dry powder coating to metal surfaces. Powder coatings are usually applied electrostatically and then cured under heating or ultraviolet light.
Sand Blast
All Metal Materials
N/A
Sandblasting is a process of cleaning and roughening the surface of the product using the impact of high-speed sand flow. Its function is to make the surface of the workpiece obtain a certain degree of cleanliness and different roughness.
Silk screening
All Metal Materials
N/A
Silk Screening is a printing technique that transforms a 2d image onto a 3D image. Normally a screen printing plate is made by a photochemical process. It uses the mesh to transfer the ink to the substrate.
UV Coating
PC, PE,
Nylon
N/A
UV coating is short for ultraviolet coating, The UV Coating is a similar process to Painting, where clean components are evenly spread with paint and are instantly dried by ultraviolet light. this gives advantages of scratch, wear, and chemical resistance.
What is Surface Roughness?
Definition of Surface Roughness
Surface roughness refers to the roughness of the surface with small spacing and small peaks and valleys. The distance between the two peaks or troughs (wave distance) is very small (below 1mm), which belongs to the microscopic geometry error. The smaller the surface roughness, the smoother the surface.
Formation Factors of Surface Roughness
Surface roughness is generally formed by the machining method and other factors, such as the friction between the tool and the surface of the part during the machining process, the plastic deformation of the surface metal when the chip is separated, and the high-frequency vibration in the process system. Due to the different processing methods and workpiece materials, the depth, density, shape and texture of the traces left on the machined surface are different.
Effect of surface roughness on parts
Surface roughness is closely related to the mating properties, wear resistance, fatigue strength, contact stiffness, vibration and noise of mechanical parts, and has an important influence on the service life and reliability of mechanical products. Generally, Ra is used for labeling.
