Selecting the Appropriate Level for Your Project
Choosing the correct PPAP level is a crucial decision that impacts the quality assurance process. Several factors influence this decision:
1. Company or Industry Requirements
You may have specific requirements for PPAP levels based on your company’s internal standards or industry regulations. For example, automotive OEMs often dictate the PPAP level needed for their parts suppliers to ensure strict quality controls.
As an example, Wang points out, “Fictiv is supplying injection molding tooling and parts for a major player in the electric vehicle industry, which requires PPAP Level 3. We’re strictly following the requirements and controls according to the PPAP defined. This is for a production output of ~700,000 pieces.”
2. Complexity of the Part
Complex parts with intricate designs or critical functions typically need comprehensive documentation to ensure every aspect of the design and manufacturing process is validated. This may include detailed Design FMEA, Process FMEA, and extensive dimensional results, so you’ll likely need Levels 3, 4, or 5.
For example, a complex assembly with numerous subcomponents will require more extensive validation than a simple, single-piece part.
3. Criticality to Function
For parts that are essential to the overall function or safety of a product, more thorough validation and documentation are required for Levels 3, 4, and 5. This may include extensive testing, qualification, and, often, your engineering team’s approval to ensure all specifications are met and risks are mitigated. For example, safety-related components, such as brake systems or airbag modules in vehicles, often require the highest PPAP levels due to their impact on overall safety.
