A complete product is not only machined mechanically, but also requires various surface treatments to achieve corrosion resistance, wear resistance, aesthetics, and improve longevity. With many years of CNC machining experience, we provide a range of services including machining, surface treatment, and assembly. In addition to CNC technology, we also have extensive experience in surface treatments. Our current surface treatment processes include: painting, baking, powder coating, sandblasting, shot peening, anodizing, thick film oxidation, micro-arc oxidation, electroplating, electrophoresis, laser engraving, silk-screening, wire drawing, mirror polishing, staining, blackening, CD lines, etching, high gloss, erosion lines, and drip adhesive, among others, to enhance the appearance of your products.

Oxidation is an electrolytic process that transforms the surface of a material into a protective film, making it less susceptible to oxidation and corrosion, thereby extending its lifespan and achieving various color effects. Commonly used oxidation treatments include: regular anodizing, brushed anodizing, hard anodizing, thick film anodizing, and micro-arc oxidation. Materials that can undergo oxidation treatment include: aluminum alloys, magnesium alloys, titanium alloys, and so on.

Electroplating:

The basic process of electroplating involves immersing the parts in a solution of metal salts as the cathode, with a metal plate serving as the anode. By passing an electric current through the solution, the desired coating is deposited onto the parts. A suitable electroplating effect can enhance the high-end and fashionable appearance of your products, making them more appealing in the market. Common types of electroplating include: copper plating, nickel plating, silver plating, gold plating, chrome plating, zinc plating, tin plating, and vacuum plating.

Electrophoretic coating:

With the continuous advancement in industrial requirements, electrophoretic coating can be customized in various colors, maintaining the metallic luster while enhancing the surface’s corrosion resistance. It has minimal impact on the precision of the product, with a typical coating thickness of about 10-25 microns, which can also be customized to be thicker.

Passivation:

Passivation, also known as chromate conversion coating, is an acid treatment process that removes surface oil, rust stains, and oxides through immersion or ultrasonic cleaning. By chemically reacting with passivation solution, it achieves the effect of preventing corrosion and extending the rust-free lifespan. The color of the passivation film may vary with different materials, and passivation does not increase the thickness of the product, so there is no need to worry about it affecting the product’s precision.

Blackening:

Blackening, also known as bluing, involves immersing the product in a chemically aggressive oxidizing solution to create an oxide film on the metal surface, effectively isolating it from the air to prevent rust. This process is suitable for steel materials.

QPQ:

QPQ stands for Quench-Polish-Quench, which involves placing black metal parts in two different types of salt baths to enable the infiltration of various elements into the metal surface, forming a composite layer. This process aims to modify the surface of the parts, providing excellent wear resistance, fatigue resistance, corrosion resistance, and minimal deformation. QPQ is applicable to steel materials.

(Note: Stainless steel products cannot undergo blackening treatment; the desired black surface effect can only be achieved through QPQ.)

Laser Etching:

Laser etching, also known as laser engraving or laser marking, is a surface treatment process based on optical principles used to create logos or patterns on products. The laser etching effect is permanent, with high surface quality, and is suitable for products made of various metal and plastic materials.

Screen Printing:

Screen printing refers to transferring patterns onto products through ink using a screen. The ink color can be customized according to customer requirements. For precise work, up to 6 colors can be used on the same product, including black, red, blue, yellow, white, and green. If you want the screen printing effect to last longer, a layer of UV coating can be applied after screen printing to extend its lifespan. Screen printing is suitable for various metal and plastic materials and can be combined with surface treatments such as oxidation, painting, powder coating, electroplating, and electrophoretic coating.

Polishing:

Polishing is done to give the product an aesthetic, transparent, and surface-protecting effect. Transparent polishing is a great choice for metal products and is divided into manual polishing, mechanical polishing, and electrolytic polishing. Electrolytic polishing can replace labor-intensive mechanical polishing, especially for complex-shaped parts and components that are difficult to process using manual or mechanical polishing methods. Electrolytic polishing is commonly used for parts made of steel, aluminum, copper, and other materials.

Drawing:

Drawing is a surface treatment method where linear grooves are formed on the surface of a workpiece using flat pressure abrasive belts and non-woven roller brushes to achieve a decorative effect. Surface drawing treatment can highlight the texture of metal materials, making it increasingly popular in modern life. It is widely used on the casings of mobile phones, computers, monitors, furniture, appliances, and other products.

Powder Coating and Painting:

Powder coating and painting are two common surface treatments for metal parts, commonly used for precision components and small batch customization. They serve to protect the surface from corrosion and rust while also achieving an aesthetic effect. Both powder coating and painting can be customized to create different textures (fine, coarse, leather grain, etc.), colors, and levels of gloss (matte, semi-gloss, high gloss).

Sandblasting:

Sandblasting is a common surface treatment method used for metal products. It can improve cleanliness and roughness, enhancing the adhesion and durability between the product and the coating. Therefore, many surface treatments choose sandblasting as a pretreatment, such as sandblasting + oxidation, sandblasting + electroplating, sandblasting + electrophoresis, sandblasting + powder coating, sandblasting + baking paint, sandblasting + passivation, and so on.

Teflon Coating:

Also known as PTFE coating, Teflon coating is a highly characteristic surface treatment that offers superior non-stick properties, heat resistance, low friction, high hardness, non-wettability, and excellent chemical resistance. It is widely used in the food industry, utensils, kitchenware, paper industry, medical equipment, electronic products, automotive products, chemical equipment, and more. It can protect materials from chemical corrosion, thus extending the product’s lifespan.

In addition to the surface treatments mentioned above, we also offer shot blasting, dyeing, CD lines, etching, high gloss finishes, etched patterns, and gel drops. For more details, please contact us.
