competitive industrial environment. Two essential tools in quality assurance are PPAP (Production Part Approval Process) and CPK (Process Capability Index). These tools help manufacturers consistently meet design specifications, reduce defects, and improve overall process reliability. In this article, we\u2019ll explore how PPAP and CPK work together to ensure high-quality production, their practical applications, and strategies for continuous improvement. Injection molding machine in production Understanding PPAP PPAP, or Production Part Approval Process, is a standardized method used to verify that a supplier can produce parts meeting customer requirements consistently.
