CNC Machining Surface Finishes

Surface Finish Options

Choose from a wide range of surface finishes for your mould parts, or keep them as-machined.

Brushed (Ra 1.2μm / Ra 47µin)

Linear pattern with uniform texture, ideal for mould plates and cosmetic parts.

Black Oxide / Blackened

Dark, attractive matte finish with rust protection for steel mould parts.

Bead Blasted

Grainy matte finish that hides machining marks, uniform appearance for moulds.

Electroless Nickel Plating

Uniform, hard coating with excellent wear resistance, extends mould life.

Powder Coated

Wear-resistant & corrosion-resistant, suitable for external mould components.

Chromate Conversion Coating

Thin protective film for corrosion resistance and better paint adhesion.

Nitriding

Superior wear & corrosion resistance, significantly extends mold service life for high-volume production.

Texturing

Covers surface defects, enhances product aesthetics & non-slip properties, ideal for cosmetic parts.

CNC Machining Advantages
