Häufige Fragen
What finish do I need for a mould?
It depends on the part requirement. SPI A1 gives a mirror gloss, A2 is a high gloss, and B grades produce a semi-gloss that hides small defects. We match the cavity finish to the target part appearance.
Why does polishing matter on light guides?
Every surface imperfection scatters light and reduces efficiency, so light guides are polished to optical quality on the faces that must transmit or reflect.
Can polishing remove machining damage?
Yes, but the process has to remove enough material to get below the damaged layer. We start with the appropriate abrasive grade rather than polishing over tool marks.

Anodizing
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.
Hard Anodizing
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.
Bead Blasting
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
Sand blasting for surface cleaning, descaling and roughening. Removes rust, scale, old coating and oxide before welding, painting or bonding.
Powder Coating
Powder coating in RAL and Pantone colours: durable, thick and impact-resistant finish for sheet metal and fabrications, from 60 to 120 µm.
