Barrel Zinc Plating

Passivates
PASSIVATES (Cr6 free option)

For Trivalent (Cr6 Free) Passivate on Zinc we offer a Clear/Blue, Thick Film Iridescent & Yellow Iridescent. Turquoise Blue Dye can be achieved on Trivalent Clear Passivate for ID purposes.

PS100 Organic Seal process can be added to Thick Film Trivalent Passivate to give excellent corrosion resistant properties.

All of the above processes can be carried out on Barrel Plated parts and are processed manually off line to allow De-embrittlement after plating.
    Technical Info

We have PLC Auto Line with 36" barrels for bulk orders, Manual 36" barrel line for the more “hands on” type jobs, 18" barrel & mini barrel for tiny batches (dabs)

If there is the slightest possibility of barrel plating a batch of components we at R.E.P. can do it with zero / minimal distortion, thus saving you the cost of jig plating.

All post treatments are available on barrel plated parts (click on Passivates)

As you may notice from some of the photographs on this website we can zinc plate that nasty, tangley job, which no one else wants!!
