February 15, 2023 Tags: , ,
The Part Submission Warrant is a crucial document in the PPAP process that accompanies the submission of an original or revised part for production. This document summarizes key information about the part and the production process. It includes the materials and manufacturing methods used, the testing procedures and results, and any other information relevant to the materials and manufacturing methods used. In a PSW, the customer’s requirements and expectations are validated to ensure that the parts submitted are fully compliant. It also serves as a reference point for any future issues or concerns related to the part. Both the supplier and the customer typically review and approve the PSW as part of the PPAP process. As any inaccuracy in the PSW can delay or complicate the production process, it is essential to ensure that it accurately represents the submitted parts. Overall, the Part Submission Warrant is an essential part of the PPAP process. This ensures that all parties have a clear understanding of what is being manufactured and that it meets all standards and requirements. In the automotive industry, the Part Submission Warrant (PSW) plays a critical role in the Production Part Approval Process (PPAP). PPAP is a standardized process that automotive manufacturers and suppliers use to ensure that all parts and components meet specifications. PSWs summarize key information about submitted parts in a detailed manner. It includes the materials used, the manufacturing process, and the testing procedure. Additionally, it contains information regarding the manufacturing facility and the production team. PPAP submissions are represented by the Part Submission Warrant (PSW). In the absence of a customer statement, a PSW is required for all part numbers. There are several things included in the PSW:
  • Describe the reason for submission (i.e., initial submission, engineering changes, parts produced at another location, change in part processing, material source change, annual revalidation, etc.).
  • Submission level to the customer (Level 1 to Level 5)
  • Declaration of part conformity to customer requirements.
  • Authorized supplier person signature along with contact information.
  • An area for the customer to indicate the disposition of the PPAP.
PSWs are typically reviewed and approved by both suppliers and customers in the automotive industry. It could be the automotive manufacturer or another supplier in the supply chain. The PSW ensures that the submitted parts meet the specifications and expectations of the customer. PSW ensures quality and consistency throughout the supply chain as part of the PPAP process. Before full-scale production begins, any potential issues or concerns related to the parts being produced can be addressed. As a result, it can be used as a reference for future issues. In the automotive industry, Part Submission Warrants play a crucial role in ensuring that all stakeholders are aware of what parts are being manufactured. Additionally, it ensures that they meet quality standards.
