Preguntas frecuentes
Electropolishing or passivation?
Passivation only cleans the surface chemically, while electropolishing removes a layer of metal, eliminating burrs and micro-defects. For high-purity medical and semiconductor parts electropolishing gives a better result.
How does it affect tolerances?
It removes material uniformly from the part surface, so we compensate by machining oversize. Sharp edges round off slightly, which is usually desirable but must be considered on precision edges.
Does it improve fatigue life?
Yes, by removing surface micro-cracks that act as crack initiators. That is why it is used on critical stainless components in demanding applications.

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.
Polishing
Mechanical polishing to mirror and optical finishes: Ra down to 0.05 µm for mould cavities, light guides, medical parts and decorative surfaces.
