Recently, we installed a new 2500 liter E-Brite Ultra CU bath for plating directly on zinc die-cast Zamac 3 alloy.
The end results were excellent adhesion utilizing saw cut adhesion test and baking at 350F for one hour then cold water quench. The copper-nickel-chrome plater found it plates faster than the competitive chemistry. The resulting copper plate is outstanding throwing power in the 6 inch deep recesses. Eliminating acid copper plating bite through challenges in a deep recess zinc die-cast part.
The customer now plates zinc die-cast substrate without ever having to bring cyanide ever into their facility by installing to E-Brite Ultra Cu.
