Oil resistant plating




2006

Dear all
problem: I am receiving machined components from vendor with plating . so after receiving I need to inspect them for which it needs to get handled and the plating gets spoiled due to moisture of hands or any other surface . so please suggest me some resistive plating process by which the plating does not get spoiled for long time.

The first step is that your employees should only be handling these parts when wearing appropriate gloves, Rehmath. Believe it. But you haven't told us what kind of plating you are speaking of or what kind of parts.

First define what kind of plating is. Meanwhile I am guessing that you are talking about zinc plated parts. If they are zinc plated parts, they are covered by a chromate surface that is spongy at the moment it leaves the line. The surface gets harder and resistant after 48 hrs. So you should let the material repose 24 hr (at least) before handling it.

Mr Rehmath
In case plating you are referring to is zinc plated yellow/white passivation I suggest you try green chromate passivation you will find its life better and resistance to handling better.I tried similar in cnc turned part for mazda with satisfactory results.
