We
offer rack and barrel zinc plating. Our two largest tanks are
12' x 2' x 6' and 8' x 3' x 3'. Both cyanide and non-cyanide
electrolyte solutions are available.
Overview: Zinc
plating offers excellent corrosion resistance and sacrificial
protection. Typically
thicknesses of 12µm can be
achieved resulting in salt spray tests of over 500 hours.

Alkaline
Zinc (bright acid zinc): We use Envirozin
100/120 (barrel/rack), an alkaline zinc solution specially
formulated to address the problems of adhesion
failure
associated with many other zinc solutions. Alkaline zinc is
also ideal for bore plating because it provides a level surface
deposit over the whole component. It also allows for much thicker
deposits than cyanide zinc and is ideal for iron castings.
Cyanide
Zinc: We use MirroMac 12 for both
rack and barrel solutions. Cyanide zinc is quicker to apply
and easier to clean than alkaline zinc.
De-embrittlement: In-house
de-embrittlement can be undertaken. Our standard service is
1-2 hours at 218°C although we can offer upto 18 hours
where required. De-embrittlement is essential for removing
hydrogen that has been deposited during the zinc plating process
which
in turn causes the material to be brittle. Oven size is 3'
x 3'
x 3' .
Passivates: A range of passivates are available. Please see our zinc
plating & passivates page.
