PPAP
PPAP stands for Production Part Approval Process and refers to a structured procedure for the approval of products and production processes, which is used in particular in the automotive industry.
As part of the PPAP process, it is verified that the customer’s requirements and technical specifications have been understood and that the planned production process is, in principle, capable of manufacturing components under defined series production conditions in accordance with these requirements.
PPAP thus represents an important step between product and process development and approval for series production.
PPAP in the automotive industry
Before series production begins, it must be demonstrated that both the component and the manufacturing process developed for it can meet the defined requirements. As part of the PPAP, various product, process and quality records are compiled for this purpose and submitted to the customer for evaluation in accordance with the agreed requirements.
These may include, amongst other things, drawings and technical specifications, process flowcharts, FMEA, control plan, measurement results, material certificates, measurement system capabilities and process capability studies. The scope and type of the documentation to be submitted depend on the specific project and the customer’s requirements.
A key document is the Part Submission Warrant (PSW). It summarises essential information regarding the submission of samples and documents the submission of the component for customer approval.
PPAP is closely linked to APQP and other Automotive Quality Core Tools. Whilst APQP structures advanced quality planning through product and process development, PPAP serves as documented evidence prior to or in connection with series production approval.
