生产件批准流程 (PPAP)

The Production Part Approval Process (PPAP) is a standardized methodology used in manufacturing to ensure that a supplier’s production process consistently produces parts that meet specified requirements. It involves a series of documentation and validation steps, including design records, engineering change documents, and process flow diagrams, to confirm that the production process is capable and reliable. PPAP is essential for maintaining quality assurance and fostering collaboration between suppliers and manufacturers in the automotive and other industries.
