Surface Finishing

Precionn has manufacturing management capabilities for all processes from raw materials, processing and manufacturing, to product surface treatment. We have rich experience in product surface treatment. According to the product materials, processing technology and the final use needs of the customer’s products, we can provide products Surface treatment suggestions can also be made exactly according to customer needs. We have the following surface treatments:

Anodizing, PVD, electroplating, powder spraying, painting and surface polishing. Our factory has qualified environmental certification, and the surface treatment coating complies with ROHS environmental requirements.

Anodizing

Anodizing is divided into ordinary anodizing and hard anodizing. The coating is 5-150 microns, and the sandblasting model is No. 80 to No. 220. It is mainly suitable for surface treatment of aluminum alloy, mainly to improve the hardness, wear resistance and wear resistance of the aluminum alloy surface. Beautiful appearance.

Custom PVD Coating

PVD refers to the process of using physical processes to achieve material transfer and transfer atoms or molecules to the surface of a substrate. It increases the hardness and beauty of product surfaces and is widely used in decorations, carbide cutting tools, fixture mold surfaces, and is suitable for various materials, including plastics, aluminum alloys, and alloy steels.

Surface Plating

Electroplating is a process that uses electrolysis to attach a metal film to the surface of metal or other materials to prevent metal oxidation (such as rust) and improve wear resistance, conductivity, reflectivity, and corrosion resistance (copper sulfate, etc. ) and improve aesthetics. Widely used in electronic industry, communications, home appliances, jewelry and decoration industries.

Surface Powder Coating

Powder spraying is an environmentally friendly and efficient surface coating method. The powder coating is evenly adsorbed on the surface of the workpiece through electrostatic action to form a powder coating. After high-temperature baking, leveling and solidification, a final coating with various effects is formed. Powder spraying is superior to the spray painting process in terms of mechanical strength, adhesion, corrosion resistance, and aging resistance. Although the cost is higher, its excellent performance makes it widely used in the automotive industry, electrical insulation, corrosion-resistant chemical pumps, valves, and outdoor steel. It is widely used in the surface coating of components, steel furniture, castings, etc.

Surface Polishing

A method of modifying the surface of a workpiece using flexible polishing tools and abrasive particles or other polishing media. It mainly repairs defects such as knife marks, bumps and scratches on the surface of the product. The product can obtain a perfect appearance after anodizing, PVD or baking paint treatment.

The Importance of Surface Finishing in Machining Process

As a widely used technology in industrial production, surface treatment plays the following important roles:

1. Improve the corrosion resistance of the product. Metal products can be coated to improve their corrosion resistance and wear resistance and extend their service life.

2. Improve the decorative performance of the product. Products can be painted, oxidized, electroplated and other decorative treatments to improve the product’s aesthetics and added value.

3. Improve the lubrication performance of the product. Mechanical parts can be coated to enhance their lubrication properties and reduce wear and friction losses.

Key Considerations When Choosing Surface Finishing

Faced with various materials and processes, how to choose the appropriate surface treatment plays a key role in meeting the performance of the product. It is mainly considered through the following factors:

1. If the product is required to have corrosion resistance and wear resistance. Mainly choose PVD and electroplating treatment.

2. If the product is required to have high appearance decoration effect, such as consumer appearance structural products. Mainly choose oxidation, baking paint, PVD and other surface treatments.

3. Different materials require different surface treatments. Aluminum is mainly oxidized and can also be powder sprayed and painted. Plastic materials are mainly painted and PVD treated. Stainless steel is mainly electrolytic polished, and other steels are mainly electroplated and painted.

4. Different manufacturing processes will also have different surface treatments. For CNC processed products, aluminum alloy is suitable for oxidation treatment, and steel is suitable for electroplating and baking paint treatment. Die-cast products, aluminum alloy are suitable for powder spraying and baking paint processing. Sheet metal products are suitable for painting and powder spraying. Powder metallurgy products are suitable for PVD processing.
