No matter what kind of product and customer group it is, when will the factory submit PPAP? Let’s share the editor’s understanding below. I hope it will be helpful to you. In the end, it still needs to be confirmed by the corresponding customer. The shared here is for reference and knowledge reserves only.
PPAP is a very good thing. Whether it is for automotive products, there is no choice and must be implemented. Such non-auto products are also an optional tool. It allows everyone to have a unified "language" for the quality standards and traceability of products and components.
For enterprises that produce mass, PPAP is definitely worth keeping on. PPAP is like a Checklist, reminding customers and suppliers what to do around a new component development. PPAP frames a range for everyone.
For quality colleagues who have just come into contact with PPAP, let’s first learn about what PPAP.
PPAP is the abbreviation of Production partapproval process in English, and is translated as the production part approval program in Chinese. PPAP is one of the five major tools of the TS16949 quality management system, used for quality control of the production process of automobiles or parts.
It is used to determine whether the supplier has correctly understood all the requirements of the customer's engineering design records and specifications, as well as whether the manufacturing process has potential in actual operation, and continuously produce products that meet customer requirements according to the production rhythm at the quotation. The purpose of the
PPAP process is to confirm whether the organization (supplier) :
- correctly understands the customer's design requirements and specifications;
- can continue to produce products that meet customer specifications;
- meets the customer's production capacity (beat) requirements.
PPAP must be applicable to the internal and external sites of organizations that provide production parts, service parts, production raw materials or bulk materials. Generally, PPAP is not required for bulk materials, but if customers have special requirements, they should be implemented according to specific requirements.
For production parts, products used in PPAP must be taken from effective production (Significant Production Run). The production process must be mass production from 1 to 8 hours, and the specified production quantity is at least 300 continuous parts, unless otherwise specified by an authorized customer representative. The products of
PPAP must be taken from effective production! The market is the only criterion for quality inspection.
By the way, let’s learn about the five major tools for quality management as follows:
There are many introductions to PPAP in various quality management books, but under what circumstances must you submit PPAP? Under what circumstances can we ask to submit a PPAP? What documents should a complete PPAP contain? Many family members don’t know about quality. In order to accumulate good deeds and benefit others, the editor will share many years of work.
. Under what circumstances must PPAP
. A new part or product;
. Corrections for previously provided non-compliant parts;
- . Product changes are caused due to engineering changes in design records, specifications or materials.
. The following eight situations notify the customer whether to submit PPAP
. Compared with previously approved parts or products, other different structures or materials are used;
. Use new or improved tooling (excluding vulnerable tooling), molds, molds, models, etc., including supplementary or replacement tooling.
- . Production is carried out after upgrading or re-arrangement of existing tooling or equipment;
5. Changes in supplier parts, different materials, or services (such as heat treatment, electroplating), thereby affecting customer assembly , Requirements for molding, function, durability or performance;
6. The tooling is stopped for mass production and re-activated for production after 12 months;
7. The parts and manufacturing processes of internal manufacturing or suppliers are changed;
8. Changes in test/inspection methods - the adoption of new technologies (does not affect their acceptance criteria).
In summary, PPAP must be submitted under the following conditions:
, five levels for submitting PPAP
Level 1: Only submit a guarantee letter to the customer (a appearance approval report is provided for the specified appearance items);
Level 2: Submit the guarantee letter and product samples and limited relevant support information to customers;
Level 3: Submit the guarantee letter and product samples and complete relevant support information to customers;
Level 4: Submit the guarantee letter and other requirements specified by the customer;
Level 5: Guarantee letter, product samples and all support data are retained at the organizational manufacturing site for review.

, temporary approval
- , reject
- PPAP Manual Fourth Edition
- IATF16949 System requirements
- Network resources
5. Files that PPAP should contain (18 basic elements)
, design record
, any authorized project change file
- , customer project approval
5, process flow chart
6, process FMEA
7, control plan
8, measurement system analysis and research
9, full-size measurement results
0, recording of material/performance test results
1, initial process research
2, file requirements for qualified laboratories (relevant laboratory file requirements)
3, Appearance approval report (AAR)
4, production part sample 5, standard sample
6, inspection fixtures and auxiliary tools
7, customer special requirements
8, Part submission guarantee letter (PSW)
PPAP Production parts approval procedure stipulates the general requirements for production approval documents including production parts and bulk materials. The purpose is to determine whether the supplier has correctly understood all the customer's requirements and whether the production process has potential capabilities. Therefore, PPAP is one of the indispensable quality tools in the automotive industry.
