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

CNC 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 services 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.
