Fast PPAP
The Production Part Approval Process (PPAP) is a standardized process in the automotive and aerospace industries that helps manufacturers and suppliers communicate and approve production designs and processes before, during, and after manufacture.
What is Production Part Approval Process (PPAP)
Production Part Approved Process defines the approval process for new or revised parts, or parts produced from new or significantly revised production methods. The Production Part Approved Process consists of 18 elements that may be required for approval of production level parts. Not all of the elements are required for every submission. There are five generally accepted Production Part Approved Process submission levels. 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.
Why Perform Production Part Approval Process (PPAP)
The Production Part Approved Process verifies that the supplier understands all customer engineering design specifications and requirements and that the process is capable of consistently producing product meeting those requirements during an actual production run at the quoted production rate. PPAP and other quality tools continue to be implemented into more industries; therefore it is important to gain an understanding of the Production Part Approval Process requirements to remain competitive as a parts supplier.
When to Perform Production Part Approval Process (PPAP)
A Production Part Approved Process is required for any new part submission as well as for approval of any change to an existing part or process. The customer may request a PPAP at any time during the product life. This demands that the supplier must maintain a quality system that develops and documents all of the requirements of a PPAP submission at any time.
