Production Part Approval Process ("PPAP") is the industry standard that ensures engineering design and specification requirements are met. The purpose of PPAP is to verify whether the supplier’s manufacturing process is capable of consistently producing product meeting all product engineering design and specifications, and demonstrate the developed packaging eliminates damage during transportation, handling, and storage.
All documents must be submitted in WFS accepted format. Download the Supplier PPAP Workbook for a detailed explanation.
