View Full Version : A problem with material being used in a PPAP - Material Changes

If a customer is having issues (adhesion levels) with material used and approved in a previous PPAP does it make sense to submit new PPAP's (for new part numbers) using the same material? (An acceptable resolution has not been determined to garantee that this problem will not re-occur using the adjustments made to this material. I don't even know if the material will be called the same part number or if it will be issued a new part number?). Yet, I'm being asked by the customer and upper management to complete these PPAP's.

It doesn't make sense to me???

Does the material meet specifications?

Yes the material is within the specifications for the material but this didn't go over big with our customer they didn't want to hear that.

I am not sure which industry you are but I am familiar with a problem that the plastic compounder "improved" his product without telling anyone and this caused adhesive problems.
Plastic materials are secret and the specs do not refer to the composition as in Metal.
Did the customer give a spec for adhesion?
Close one issue before opening another

OK, the material is "good," but it's failing. The operation was a success, but the patient died. It doesn't matter much what the customer wants to hear; if their design is screwed up, and your company had no reasonable way of knowing it, it's their problem. You can offer to help them out of it, but you should never accept blame for a problem you had nothing to do with.

That being said, if this customer is aware of the problem, and your management is aware of the problem, but they want you to submit PPAPs anyway, there isn't much you can do about it. In submitting PPAPs I would not cop to anything being nonconforming if it meets specifications.
