Plating Racks


#1

Does anybody know were I could find plating racks for lapel pins, We
have tried to build our own and had them coated with Plasti-Dip and
powder coated but they dont last long in cyanide based gold
solutions. We have a contract to produce 10,000 pcs monthly and
"wiring by hand with copper" is just not productive enough to get the
job done.

Any advice or thoughts would be greatly appreciated,

Thanks

We have electroform plating racks with threaded post & PVC nuts with
rubber sealing washers. The washers are worn out & need to be
replaced however the rubber I have tried so far the plte migrates
onto the washer & has to be picked off after 1 rack. Any ideas on
what kind of material could be used for this purpose wuld be helpful.

I’m not real clear on the exact construction of your racks -
www.plastidip.com (Plasti Dip International) carries the rubber that
plier handles are coated with - among many other things - it’s a
consumer product, not 55gal. drums only.

Plastic dip is a good coating for plating it will still have some
migration but will allow many platings before hand.

Many years a go I worked in a printed circuit board plating shop and
we used Plasti-Dip to seal the connection between the flexible
fingers on the racks and the frame of the rack . We would tighten
the fastener then coat the area with the Plasti-Dip. It would
generally make a good seal. BTW Plasti-Dip is a brand name for
plastisol resin which I believe is PVC dissolved in a solvent.
