Low-Volume Turning Milling (50-1000 Pcs)

Turning projects with small batches below 1,000 pieces are mainly for product R D prototyping, prototype validation, non-standard mold/die-casting mold parts, equipment maintenance spare parts, customized precision shafts, sleeves and pins, automotive/medical sample parts, and other trial production, customization and supporting projects.

Hight-Volume Mass Turning

Turning projects with large batches of 1,000 pieces and above are mainly for standardized mass production and large-scale supporting industrial orders, such as pins, shafts and sleeves for die-casting applications, electronic connectors, motor shafts, precision sensor components, automotive standard fasteners, and batch precision metal rotational parts.

CNC Machining Surface Finishes

Surface finishing is a processing that can change the finished part's surface to specific color, appearance, property. It gives the finished part different properties of resistance to corrosion, hardness, conductivity, etc. that out of the material itself.

High-gloss Polishing

The final part surface reflects light like a mirror. All machining marks disappear completely.

Anodizing

A dense oxide film forms on the surface of the metal CNC part. The color can be customized. Hardness and corrosion resistance improve significantly.

Powder Coating

The CNC part receives a thick, textured or glossy plastic-like layer. It feels warm to the touch and the colors appear vivid.

Electroplating

The surface of the CNC machined part becomes a metallic coating, such as bright nickel or chrome. It shows a highly reflective metallic luster and resists corrosion better.

EMI Shielding Coating

The workpiece surface receives a thin, electrically conductive layer. It provides electromagnetic shielding function. Its appearance looks similar to spray painting.
