I have a question. My plant makes a very small part for automotive interiors. We refer to it as ISO FIX marker. It is the small plastic button that has the baby in the baby seat, mostly in the backseat of vehicles. These parts are used in domestic and imported vehicles. Our customer asks for the a PPAP for say, Toyota Tundra application for a black button, then the next month they ask for Toyota Corrolla application for the same black button. We are doing these for free, so you can imagine the amount of these I am being asked to complete. Fifteen this week. Usually 10-20 a month. My questions are, should I have to redo this everytime? Does anybody else do this? Should the PPAP even reference their part number? or should it just have my part number? These guys drive me crazy..........please help.
