PPAP - introduction

The PPAP (Production Part Approval Process) elements are a series of documents and requirements used in the automotive and manufacturing industries to ensure that suppliers meet the necessary specifications and quality standards for production parts. The standard PPAP package includes the following elements:

• Design Records: Detailed drawings and specifications for the part.

• Authorized Engineering Change Documents: Any approved changes to the design records.

• Engineering Approval: Confirmation that the part meets all engineering requirements.

• DFMEA (Design Failure Mode and Effects Analysis): A risk management tool that identifies potential design failures.

• Process Flow Diagram: A step-by-step representation of the manufacturing process.

• PFMEA (Process Failure Mode and Effects Analysis): Analysis of potential process failures and their effects.

• Control Plan: A detailed plan for controlling and monitoring the manufacturing process.

• Measurement System Analysis Studies: Studies to ensure the measurement systems are accurate and repeatable.

• Dimensional Results: A report of actual measurements taken from production parts.

• Records of Material / Performance Tests: Documentation of tests to verify material and performance specifications.

• Initial Process Studies: Statistical analysis of process capability.

• Qualified Laboratory Documentation: Certifications of the labs that performed any required testing.

• Appearance Approval Report: Verification that the part meets all appearance requirements.

• Sample Production Parts: Samples from the production run for inspection and testing.

• Master Sample: A reference part kept for comparison with future production.

• Checking Aids: Tools used for inspection and measurement of the part.

• Customer Specific Requirements: Any additional requirements specified by the customer.

• Part Submission Warrant (PSW): A summary document confirming that all PPAP requirements have been met and the part is ready for production.

These elements ensure that the supplier can consistently produce parts that meet all quality and performance standards.
