A. That's a long time in the plating line. Are you plating zinc? To what thickness, and with acid or alkaline zinc? 6 RPM is not unusual although some shops would use 4 RPM for large barrels.

Gear box rotatation speed influences the plating result?
Q. Hi everybody,
I am working in zinc plating company for 3 months. So, I not sure about the rotation speed of the gear box will influence the plating result or not?
Our factory plating machine is produced by Taiwan company. There are 24 barrels for plating and control by 4 ampere machine.
Anyone that can help me, please post your answer, I will appreciate it! Thank a lot!

A. You want sufficient rotation speed for solution transfer, parts movement, and even exposure of all surfaces for plating, but no more than necessary (to limit abrasion and possible parts damage). 4 to 6 RPM is pretty typical for production sized barrels. Please clarify what you mean by 4 Amp machine. Thanks!
