Max Spare uses PPAP - Production Part Approval Process to define requirements for the production part approval. This includes production and bulk materials
The purpose of PPAP is to determine if all customer engineering design records and specification requirements are properly understood. The process has the potential to produce products consistently meeting client requirements during an actual production run, at the quoted production rate.
The PPAP documentation is provided whenever a new or modified seal is introduced into production, or if the manufacturing process is changed. If required, sample parts and documentary evidence can be provided showing that the process to meet the specific demands of various customers has been followed.
