CNC Machining

CNC machining is suitable for plastic and metal parts and can be used to make from one single prototype to up to 500 parts.

A wide variety of materials can be machined, including mild and stainless steel, aluminum, magnesium, zinc, brass and many plastics.

We also offer the production of precision-machined components. Our precision engineering department offers milling, turning, CNC engineering, surface grinding, wire erosion, EDM spark erosion and more. All of your projects will be discussed carefully and checked before production starts. During and after production the parts will be 100% inspected and we can provide original certificates for all materials used in the project as well.

Sheet Metal Parts
Sheet Metal Parts
Sheets Metal (Typically 0.03 mm to 3.0 mm), are placed into carious types of presses and then formed into intricately shaped parts. The sheet metal is forced, bent, stretched, twisted, punched, and cut into individual parts or assemblies and often finished in paint or powder coat.
Milled Parts
Milled Parts
Milling is used to apply a machined surface finish on plastic or metal or for creating complex 3D shapes. We use CNC machining centers with quick-change tooling, programmed using advanced Delcam software. Sometimes if the clients asked anodize or any surface finish, we need to polish the surface to achieve the smooth finish.

Finishing Services Tolerances

Our general tolerances for CNC machining of metals is DIN-2768-1-fine and for plastics DIN-2768-1-medium. Tolerances are greatly affected by part geometry and type of material, and cannot be guaranteed. Our project managers will consult with you on every project and will seek to provide the highest degree of precision possible.



Please kindly refer to our CNC machining materials list.

You can choose from a variety of finishing services for machined parts, including surface grinding, knurling, honing, painting, printing etc. At Star, we understand that the finish of your part or product is just at Tuowei as the features, so we have a range of experts in house who specialize in different finishing techniques.
