CNC Milling services

DONGGUAN CHENGYANG utilizes 3-axis, 4-axis, and 5-axis CNC milling to manufacture parts from over 40 different plastics, metals, and rubbers. For both small and large-volume production, first article inspection (FAI) is available upon request. We achieve tolerances of up to +/- 0.0004” (0.01mm). Additionally, we offer competitive pricing for various heat treatments (aging, annealing, quenching, tempering, and more) and surface treatments (anodizing, chromate plating, passivation, etc.).

3 Axis CNC Milling

Three-axis CNC milling is the most common type of CNC machine, offering high precision, efficiency, and cost-effectiveness for most parts. We will provide most sufficient maching services.

4 Axis CNC Milling

4-axis CNC milling provides greater flexibility for machining multi-sided parts and curved surfaces. While the cost is slightly higher than 3-axis machining,.

5 Axis CNC Milling

A 5-axis CNC machine is capable of machining highly complex shapes, making it ideal for parts with curved surfaces or intricate features that require processing from multiple directions.

Our experienced professionals specialize in product surface treatment.

Name Description Materials Color Texture More
Brushing Brushing is a surface treatment technique that creates decorative lines on the workpiece by grinding the product, resulting in a beautiful and aesthetically appealing finish. Aluminum, Brass, Stainless Steel, Steel, ABS,etc N/A Satin
Sand Blast Sandblasting is a method that uses high-speed sand flow to clean and roughen the surface of a product. It serves to achieve a specific level of cleanliness and varying roughness on the workpiece surface. All Metal Materials, Plastic N/A Matte
Tumbling Tumbling is a surface treatment process where materials are placed in a rotating drum or container with abrasive media. The action of tumbling smoothens surfaces, deburrs edges, and improves uniformity. All Materials N/A Smooth, Matte
Polishing Polishing is a mechanical surface treatment process that uses abrasives or buffing wheels to remove imperfections, smooth surfaces, and enhance the appearance of materials, leaving a shiny and reflective finish. All Materials N/A Smooth
Anodizing Anodizing is a surface treatment for aluminum and its alloys. It forms a protective layer that boosts corrosion resistance, wear resistance, and hardness while changing the material’s surface appearance. Aluminum, Titanium Clear, Yellow,
Green, Blue,
Black, etc
Smooth, matte finish.
Painting Attach the product to be sprayed onto the rotating bracket, and then secure the bracket on the assembly line. Apply the paint evenly to the product’s surface. This process enhances the product’s tactile feel, but it may be susceptible to scratches. All Materials Clear, Yellow, Green, Blue, Black, Multiple Gloss, semi-gloss, flat, metallic, textured
Black Oxide Black oxide is an oxide film primarily utilized to enhance product corrosion resistance and appearance, while reducing light reflection. It is well-suited for treating steel and stainless steel surfaces. Steel, Stainless Steel Black Smooth, matte
Electroplating Electroplating serves functional, decorative, and corrosion-related purposes, finding widespread use across various industries. For instance, the automotive sector often employs chrome-plating on steel automobile parts. Aluminum, Steel, Stainless Steel Gold, Silver, Nickel, Copper, Brass, Zinc, Chrome Smooth, glossy finish
Powder Coating Powder coating is a technique for applying dry powder to metal surfaces, typically done electrostatically. The coated metal is then cured through heating or ultraviolet light to create a durable and attractive finish. Aluminum, Stainless Steel, Steel,etc Custom Gloss, matte or semi-gloss
Alodine An alodine finish is a conversion coating applied to aluminum parts, creating a thin protective film that helps prevent corrosion. It also serves as a primer for further painting processes. Aluminum, Stainess Steel Clear, Gold As machined
Passivation Passivation used on stainless steel to enhance corrosion resistance. It involves immersing the metal in an acid solution, removing contaminants, and forming a protective oxide layer on the surface, preventing rust and corrosion. Stainess Steel N/A Matte
Electroless Plating Electroless plating is a chemical process depositing metal onto a substrate without an external electrical current. It involves a catalytic reaction between the substrate and a metal ion solution, creating a uniform and adherent coating. Metal, Plastic Gold, Silver, Nickel, Copper, Brass, Zinc, Chrome Smooth, glossy finish
