PPAP is the abbreviation of English Production partapproval process, and Chinese translation is Production Part Approval Process. PPAP is one of the five tools of the TS16949 quality management system, which is used for the quality control of the whole vehicle or parts production process.

There are many introductions about PPAP in various quality management books, but under what circumstances do you have to submit PPAP? When can a PPAP be required? What documents should a complete PPAP contain? Many quality family members do not know that, in order to benefit others, the editor will share many years of work experience:

1. Under what circumstances must PPAP be submitted

1. A new part or product;

2. Correction of previously provided non-conforming parts;

3. Changes in products due to engineering changes in design records, specifications or materials.

2. The following eight situations are notified to submit PPAP

1. Compared with previously approved parts or products, other different structures or materials are used;

2. Use new or improved tooling (excluding vulnerable tooling), molds, forming dies, models, etc., including supplementary or replacement tooling.

3. Production after upgrading or rearranging existing tooling or equipment;

4. Change of production location (tooling and equipment are transferred to different factories, or production is carried out at a new factory site);

5. Changes in the supplier’s parts, different materials, or services (such as heat treatment, electroplating), which affect the customer’s assembly, molding, function, durability or performance requirements;

6. The tooling is restarted for production after it has stopped mass production for 12 months or more;

7. Changes in the parts and their manufacturing processes made in-house or by suppliers;

8. Changes in test/inspection methods – adoption of new technologies (without affecting their acceptance criteria).
