Summary

Allow the Parts to achieve a silvery hue.  If they do not, add, in sequence, more Promoter and Zinc Dust.

After the Parts have been Coppered, you should add the Promoter:

Let the Parts Copper, which should take 4-8 minutes or less in a clean system; if the parts don't Copper, make sure the pH is below 2, and add more Copper.

Coppering

Load 500 pounds of Oil-Free Pins and Media to the Barrel
Adjust Water Level and Water Temperature to 70° to 75° F.

Zinc Flash

Be sure to mainting the pH below 2; plating will stop if the pH rises above 2.5.  
Adjust the pH with Sulfuric Acid.
Check the thickness before discharging the Parts from the barrel.

Cleaning

SURFACE AREA, LOAD, THICKNESS & ADD INFORMATION 

Add   1.00 pounds or 16 ounces of  Zinc Dust
    or
453.6 grams of  Zinc Dust
Allow  5 minutes and 0 seconds between adds.

Allow the metal to plate out for 5 minutes after the last additional of metal, keeping the pH below 2.  You may wish to water-polish during this part of the cycle.

Let the Media and Chemistry fully clean the Parts, particularly in difficult-to-clean areas, before going to the Copper Step.

You should make 5 adds of Zinc Dust, each consisting of:

Add  17.0 fluid ounces or 503 milliliters of Sulfuric Acid (66 Baume)
