Surface Finishing

Finishing is where cosmetic parts are won and lost, so we run our own line and control the batch record instead of sending parts to a third party and hoping.

Aluminium can be clear or black anodised, hard-coated for wear resistance, bead-blasted for a uniform matte look, or brushed for a directional decorative grain. Steel goes to passivation, zinc flake or electroless nickel; plastics receive adhesion-promoted primer, base coat and a matte or gloss clear.

For production parts we set the standard first: a signed limit sample for colour, gloss and texture, plus a specified coating thickness range measured by eddy-current or destructive test coupons on every batch.

Frequently asked

Yes — anodising grows the surface by roughly half the coating thickness and paint adds 30–80 µm. We compensate in machining before you see it.
Silicone plugs, tape and custom jigs handle most cases; tell us which faces must stay bare and mark them on the drawing.
