Plastics
Engineering plastics like ABS, POM, and PC are lightweight, cost-effective, and easy to machine. They’re suitable for functional prototypes, insulation components, housings, and parts requiring impact resistance or electrical isolation.
If you have special material requirements, please leave a message with the specific specifications, and our engineers will evaluate them for you.
From powder coating to anodizing, we offer a range of finishing processes to improve part performance and appearance.
As Machined
The part is left as-is from CNC machining, offering a cost-effective solution with visible tool marks and a standard roughness of 3.2 μm (126 μin), plus deburring for safe handling.
Anodizing enhances corrosion and wear resistance by forming a protective oxide layer on aluminum or titanium surfaces. It also allows for decorative coloring and improves overall part durability.
Bead Blasting
Bead blasting produces a uniform matte finish by removing surface imperfections. Commonly used to improve appearance before anodizing, plating, or coating.
This dry finishing process applies powder to metal parts, then cures it into a tough, uniform coating. It offers excellent durability and is available in many colors and textures.
Electroplating uses electric current to deposit a metal layer onto a part, enhancing hardness, conductivity, and appearance with finishes like chrome or nickel.
Polishing removes surface flaws and creates a reflective, smooth finish. It’s used to improve aesthetics, reduce friction, and prepare parts for secondary coatings.
Brushing applies a fine, directional texture using abrasive belts or pads. Often used for decorative metal finishes or to visually mask minor surface defects.
Applied primarily to aluminum, Alodine coating creates a corrosion-resistant and paint-ready surface, significantly improving both protection and finish durability.

CNC Machining Overview
01 What Is CNC Machining?
CNC (Computer Numerical Control) machining is a subtractive manufacturing process that uses computer-controlled tools to remove material from a solid block. By following pre-programmed instructions, machines precisely cut, drill, or mill raw materials—such as metal or plastic—into highly accurate and repeatable parts for industrial use.
02 How Does the CNC Machining Process Work?
The process starts with a 3D CAD design, which is converted into toolpaths by CAM software. CNC machines then follow these digital instructions to cut, drill, or mill material into a final part.
03 Why Choose CNC Machining?
CNC machining offers high precision, excellent repeatability, and faster production compared to manual machining. It’s ideal for prototypes and production parts that demand tight close tolerances and consistent quality.
04 How Much Does CNC Machining Cost in China?
Pricing varies by complexity, material, and shop scale. Basic 3-axis machining can cost $10–30/hour, while more advanced setups may charge more. In China, rates are generally lower than in Europe or the U.S.
05 What’s the Difference Between CNC Machining and 3D Printing?
CNC machining is subtractive—cutting from solid blocks—while 3D printing is additive. CNC offers better strength, tighter tolerances, and more material options, especially for functional or end-use parts.
06 What Materials Can Be Used in CNC Machining?
Common materials include aluminum, stainless steel, brass, ABS, POM, and PC. The process supports both metals and plastics, depending on the application and part function.
