Surface Finishing Overview
To ensure that the parts meet the desired process standards, perform stably and optimally in practical applications, and maintain their best condition, we conduct surface treatment operations after completing the appropriate processes or all machining procedures. This process includes polishing, texturing, painting, anodizing, coating, electroplating, and related techniques. These treatments are like dressing the parts in a "multifunctional outer layer," which not only significantly improves the appearance quality of the parts, making their texture more refined and aesthetically pleasing, but also provides comprehensive protective properties. In terms of stress relief and oxidation resistance, they effectively delay the aging process of the parts. In removing surface defects, they ensure the parts are put into use in perfect condition. Additionally, they significantly enhance properties such as chemical corrosion resistance and wear resistance, greatly extending the service life of the parts and enabling them to handle various complex working conditions with ease, operating stably and efficiently.

Factors to Consider When Choosing a Surface Treatment
Production Speed of the Surface Treatment Method: Consider the required delivery timeline. Evaluate the time involved in executing various procedures for alternative mixed-metal surface treatment options.
Hardness of the Metal is particularly important when applying secondary techniques. Harder metals require stronger abrasives during processing. Conversely, excessive force on softer materials may cause irreparable or difficult-to-repair damage to the parts.
Cost and Financial Projections: While several processes may seem ideal for your specific situation, some more challenging tasks may require specialized tools and equipment, potentially leading to budget overruns. Assess whether your decision will result in long-term cost savings.
Surface Finishing Services Capabilities
Anodizing
Anodizing is an electrochemical process that creates a protective oxide layer on the surface of metal parts, enhancing their durability and resistance to corrosion. It works by immersing the metal in a chemical solution and passing an electric current through it, causing the metal to oxidize.
Standard: MIL-A-8625F, AMS2469,AMS2470 or AMS2471
Colors: Anodized natural, black, green, red
Test Specification: ASTM B117 336H
Application: Aerospace
Electroless nickel plating
Electroless nickel plating is a chemical process that deposits a nickel-phosphorus alloy onto a metal substrate without using an electric current, offering uniform coatings with good corrosion and wear resistance. Standard: GB/T 13913-92
Plating type: Electroless nickel
Test index: Hardness>800HV
Application: Automotive industry
Chrome plating
Chrome plating is a technique of electroplating a thin layer of chromium onto a metal object. The chromium layer can be decorative, provide corrosion resistance, facilitate cleaning, and increase surface hardness. Sometimes it may be used for aesthetic purposes.
Standard: GS 90010
Type of plating: Decorative chrome
Plating testing standard: CASS 48H; NSS 360H.
Application: Automotive industry
Polishing
Custom CNC machining parts are manually polished in multiple directions. The surface is smooth and slightly reflective.
Polishing Level: SPI A1 to B1
Roughness: Ra0.005 to Ra 0.05
Material: All materials
Powder Coating
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.
Color： Custom surface finishing
Texture： Glossy
Price： based on the requirements of the customer.
Material： All metal materials
Painting
Painting involves spraying a layer of paint onto the surface of the part. Color can be matched to a Pantone color number of the customer's choosing, while finishes range from matte to gloss to metallic。
Color: Custom
Texture: Gloss, semi-gloss, flat, metallic.
Price:
Material: Aluminum, Stainless Steel, Steel
Black Oxide
Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance, and to minimize light reflection. To achieve maximal corrosion resistance, the black oxide must be impregnated with oil or wax.
Color: black
Texture: Smooth, matte。
Price: based on the requirements of the customer.
Material: Steel, Stainless. Copper, Zinc.
Bead/Sand Blasting
Bead/Sand blasting, also known as abrasive blasting, is a process that uses compressed air to propel abrasive materials against a surface, smoothing, cleaning, or roughening it.
Color: custom.
Texture: custom.
Price: based on the requirements of the customer.
Material: all materials.
