Plating Process Control Sheet Template

If you are paying a fair price for the electroplating, I (personally) would remind the plater what a NDA means and that if they chose not to work with you, you may start looking for a plater that will work with you.
Their choice!
That said, I am aware of at least one MAJOR US firm that browbeat the plater into disclosing a very proprietary process of EN on Ti way back in the earliest stages of this work. A senior employee took the information to another plating shop that he was part owner of and under bid the original plating shop.
It does happen, so you need to put some teeth in the NDA.

A. Dear Joe,
making the SPC for special process like, plating , coating, heat treatment, etc. is very difficult or not possible also.

inside the barrel how the parts are rotating or moving we are not able to control, and you are not able to do the process for the same surface area parts in all the batches, all the inputs are variables, and many more reasons.

if you are asking the peoples for the SPC studies, they will give in paper's not on real

may be for SPC is ok for machining and stamping, etc.

A. Before you spend too much energy inventing a new system, take a look at..

I can send you an example job sheet if you want to go the 'manual' route

A. Dear Joe,

Much more to say about this. You can approach it from 2 ways....negative is: not having an adequate Control Plan and SPC system makes you unsuited as supplier for serious customers in the long run. If you look in the aerospace or automotive industry, it's not a question mark IF you have to work systematically, it's only a question mark to what extent.
The positive side is that it gives any company a better insight in what the real influences in the process are (and not only by assumption). I cannot understand that, while having an NDA, a company tries to hide something, unless they know themselves that they do a "lousy" job. Finally as a customer, you have no choice but to work with the professional suppliers and all this systematics helps to improve a supplier and make them able to continuously deliver a constant quality. With a PPA you can think about the occurrence of possible disasters and how to prevent them, with the 8D and FMEA you can prevent the re-occurrence of disasters, with SPC you can connect critical process data to product quality, with a control plan you assure the equal way for everyone to check the process, with SOP's people know how a certain job needs to be done. With DOE you can determine the important influence factors in your process and after this, only some "black magic" remains, due to parameters you're still not aware of. I can assure you that the number of these parameters slowly is greatly reduced. Ted is also right, the basics are important and have to be included too. Many approaches die (and cause only lots of frustration) because people start at the top of the pyramid, instead of starting with a good simple fundament and continue the road from there. In my opinion, a supplier should be glad if a customer is willing to help in this process, it's in the interest of both. Reasons why it could go wrong is that either your supplier is incapable (from knowledge point of view or from staffing point of view) or that you insist on doing a lot of additional work in his/her opinion, without willing to pay for this. This part of the discussion is always difficult, as in general the supplier will benefit from the systematic approach, but if you are one of the first customers who comes with a lot of additional requests which give a lot of additional work to your supplier, for sure they will not be happy. Especially not if your turn-over is relatively low for yr supplier.
It will be a long road anyway, counting in many months more than only weeks...

Good luck,
