PPAP--the working procedure of PPAP

ppap is short for Production part approval process.

The working procedure of ppap:

1. In the following cases, PPAP approval documents must be submitted to the customer product approval department before the first batch of products is shipped, unless the customer department responsible for product approval waives this requirement:

a. New products or parts;

b. When a previously submitted product or part nonconformity is corrected;

c. Engineering changes to design records, specifications or materials for production product/part numbers. All applicable fields in the PPAP document shall be reviewed and updated as necessary to reflect the production process. The PPAP document must contain the name and date of the person who granted waiver by the customer's responsible product approval department.

2. Notification of any of the following design and process changes must be submitted to the Customer Product Approval Department (the customer may therefore decide to require PPAP approval):

a. uses a different construction or material than previously approved products or parts;

b. Use of new or improved tooling (excluding consumable tooling), molds, models, etc., including additional or replaceable tooling;

c. Production after refurbishment or rearrangement of existing tooling and equipment;

d. Transfer tooling or equipment to other production sites or new production sites for production;

e. Subcontractor's changes to parts, non-equivalent materials or services (e.g. heat treatment, electroplating) that affect customer fit, shape, function, durability performance requirements;

f. The tooling is put back into production after cessation of mass production for 12 months or more;

g. Product or process changes involving production parts manufactured in-house or by subcontractors. These parts can affect the fit, shape, function, performance and/or durability of the products sold. In addition, the company must agree on any application made by a subcontractor before submitting it to the customer;

h. Changes in test/inspection methods - adoption of new technologies (without affecting acceptance criteria).

3. The marketing department is responsible for contacting customers for approval of production parts. When the customer approves the production parts, the marketing department submits the customer's production parts approval procedures and related regulations to the project planning team (if the customer does not require it, the company implements the third level of the "PPAP Manual"), which is formulated by the project planning team. "PPAP Schedule", after being approved by the general manager, assign specific tasks to all relevant departments. The plan should include the executive department of the task, the project leader, and the deadline for completion.

4. Each functional department completes the relevant tasks according to the PPAP plan.

5. Each functional department is responsible for the correctness of the technical data or actual samples provided, and submits it to the engineering department for summary.

6. The Marketing Department is responsible for contacting customers and determining the order of submission of PPAP related materials, actual samples and submission time.

7. After the production parts are approved by the customer, the company should ensure that the production conditions and processes are consistent with the production parts.

8. The engineering department shall collect and organize the approved documents and materials (PPAP document package) of the company's production parts, and archive them. The minimum filing period is the product in-use period plus one calendar year (if necessary, it can be provided by the customer), unless otherwise specified by the customer.

9. Approval for production parts of subcontractors:

a. Execute production parts approval for sub-contractors who provide materials, parts and co-processing for the company.

b. The subcontractor shall submit the production parts samples, dimensional results, material test results, performance test results (if applicable), and parts submission guarantee to the company.

c. The approval of the sub-contractor's production parts shall be carried out by the Marketing Department in conjunction with the Engineering Department and the Quality Assurance Department.
