常见问题解答
Which plating suits electrical contacts?
Gold over nickel for low-resistance, corrosion-free contact surfaces; silver where the highest conductivity is needed but tarnish can be managed; tin for solderable terminations.
What does hard chrome do?
It gives a very hard, low-friction surface that resists abrasion and rebuilds worn shafts. It is applied thicker than decorative chrome and then ground to final size.
Do you mask areas?
Yes, we mask threads, bores and mating faces so plating does not change critical dimensions, and we document the masked zones on the process sheet.

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.
