It removes a few microns at most, which matters only on very tight tolerances. Where a fit is critical we mask that area or schedule the finish before final machining.
Yes, at lower pressure. Bead blasting gives moulded and printed plastic parts a uniform matte look and can hide layer lines on 3D prints.
Fine scratches disappear; deeper gouges get blended but remain visible as soft shadows. We flag any part where the damage is too deep to hide.
Type II and Type III anodizing for aluminium: clear, black and colour finishes with improved corrosion and wear resistance, thickness from 5 to 50 µm.
Type III hard anodizing builds a 25-50 µm ceramic-like oxide layer with up to 500 HV surface hardness for wear-critical aluminium parts.
Sand blasting for surface cleaning, descaling and roughening. Removes rust, scale, old coating and oxide before welding, painting or bonding.
Mechanical polishing to mirror and optical finishes: Ra down to 0.05 µm for mould cavities, light guides, medical parts and decorative surfaces.
Powder coating in RAL and Pantone colours: durable, thick and impact-resistant finish for sheet metal and fabrications, from 60 to 120 µm.
