CNC Prototype Parts

CNC prototype parts are important for testing and verification during product development. Our prototype machining service helps you reduce risk when launching new products. We support fast conversion from designs to physical samples. Common materials include 6061 and 6063 aluminum, engineering plastics such as ABS, PC, nylon, and POM, and 304 stainless steel. We recommend using the same material as your final production parts. This provides reliable results for assembly and strength testing. We use 3-axis and 5-axis CNC milling to machine parts from solid blocks.

These CNC prototype parts can achieve standard tolerances of ±0.05 to ±0.10 mm. Key fitting areas can achieve tighter tolerances of ±0.03 mm. Surface roughness for appearance prototypes ranges from Ra 3.2 to 6.3 μm. Assembly reference surfaces can achieve Ra 1.6 μm. We can machine curved surfaces, grooves, steps, complex shapes, holes, and threads. Post-processing depends on the material. Aluminum parts receive deburring, sandblasting, and basic anodizing. Plastic parts receive sanding, painting, and silk screening. Stainless steel parts receive sanding, brushing, and passivation. Our R&D team has extensive experience in prototype development.
