Laser marking through the anodic layer
Bead blasted satin base
Polished bright base
Yes, the oxide grows inward and outward, adding roughly half the layer thickness to each surface. For tight bores we machine undersize so the finished part is on size.
It reveals them. Anodizing is translucent and any scratch or tool mark shows through, so cosmetic parts are bead blasted or polished before anodizing.
Black and dark tones are most stable in sunlight. Bright reds and yellows fade faster on exterior parts, so we advise UV testing for outdoor applications.
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.
Glass bead blasting for a uniform satin finish on metal and plastic parts. Hides tool marks, prepares surfaces for coating and gives a premium matte look.
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.
