Hi all, I am new on this forum, but have to say find a lots of interesting topics, questions & answers. We have troubles with contamination (foreign parts,no our production) of parts from Platers & Heat treaters. Do you have experiences with it? Nobody from them would like to guarantee parts without contamination. Do you some PPM rules for this issue or did you find some better technical solution for it (sorter line, etc).
Thank you very much for feedback. Cheers, Jan

That condition is also known as mixed lots and is the most frequent problem for outsourced parts. You can demand that the source use sorting to eliminate this condition. Manual sorting is common, as is automated sorting.

Yeah, I know about sorting to eliminate this condition. I would like only to know if you have some special conditions and contract with your suppliers/customers aboput PPM, sorting, etc. in that case. Manual sorting for screw, fasteners & other small products is really complicated and as you know visual(manual) screening is not 100% ( I mean in rules of quality)

Special contract conditions? Yes, that is used. Required quality levels can be zero, one, two, etc. PPM. Sorting can be specified explicitly (manual, automatic, either). Of course, the contract can be written that customer rejection of a single piece means rejection of an entire lot (or no payment, or reduced payment, etc.), so many suppliers will double sort with automated equipment to avoid problems.
