(PPAP) Production Part Approval Process (2024)

FAQs

What is the PPAP production parts approval process? ›

Production Part Approval Process (PPAP) is used in the Aerospace or automotive supply chain for establishing confidence in suppliers and their production processes. Actual measurements are taken from the parts produced and are used to complete the various test sheets of PPAP.

The AIAG SPC and PPAP manuals recommend at least 100 samples. Sometimes collecting samples can be difficult or costly. Either way, using Minitab's confidence intervals you will get a better sense of the variability and avoid costly mistakes that could come as a result of a small sample size.

The timeline for PPAP can vary widely depending on the complexity of the parts, the level of PPAP required, and the efficiency of communication between suppliers and manufacturers. It can take anywhere from a few weeks to several months.

The PPAP manual contains detailed information, guidelines and sample documents useful for completing the process requirements. The resulting PPAP submission provides the evidence that the supplier has met or exceeded the customer's requirements and the process is capable of consistently reproducing quality parts.

PPAP (pronounced P-PAP) is a manufacturing inspection process used to verify a supplier's ability to reliably and repeatedly produce a part or components for mass production. PPAP validates a production process by inspecting parts before, during, and after a production run.

Who is Responsible for PPAP? Suppliers are responsible for the PPAP process. Responsibilities include maintaining a system that documents all the necessary elements required for PPAP submission.

Currently, the only parts requiring PPAP approval are those used by the automotive industry. The Automotive Industry Action Group (AIAG) mandates PPAP approval for the automotive industry.

During the PPAP, the organization must submit 18 elements to the customer, which guarantee that the supplier is able to meet the appropriate quality and quantity requirements for the manufactured product. All of them are listed below: Design Records. Engineering Change Documents.

Some manufacturers charge upwards of $300 or more for each PPAP package.

How to do a PPAP audit? ›

Generally, it is the inspection that is done to the first piece that comes off of an assembly line or manufacturing process, AFTER A CHANGE IS MADE. The First Piece Approval goes over the new part and makes sure the new features/shapes are in place and working.

1 In an approval process, the parts you define are: Steps, approvers, and actions.

PPAP stands for production part approval process. It is a comprehensive quality assurance method used in the manufacturing industry. It ensures that produced parts meet customer requirements and specifications.

Phased PPAP separates the PPAP process into three phases: Phase 1 is called 'Quality Verification' ❑ Phase 2 is called 'Production Verification' ❑ Phase 3 is called 'Capacity Verification'. Note: For less complex components/commodities/production streams, it is possible to complete multiple phases as a single event.
