The Production Part Approval Process (PPAP) is a standardized method that helps ensure product quality by verifying that all necessary steps have been taken during the product development and production process. This process is particularly critical for the automotive and aerospace industries but can be applied to any industry where quality control is essential. This blog will delve into the Production Part Approval Process in detail.
What is Production Part Approval Process (PPAP)
The Production Part Approval Process (PPAP) is a standardized process utilized in the automotive industry to ensure that suppliers meet the necessary quality standards for their manufactured components. PPAP is a significant component of Advanced Product Quality Planning (APQP) and is typically required for suppliers to obtain approval from Original Equipment Manufacturers (OEMs).
PPAP outlines a series of activities suppliers must undertake to prove that their products meet the customer's requirements, regulatory bodies, and industry standards. The process includes submitting various documents, including design specifications, engineering drawings, material certifications, and test results. PPAP also requires the supplier to conduct tests and inspections to ensure the components meet the required specifications
PPAP includes five levels, each with specific requirements that must be met before the supplier is authorized to produce the component. The process demonstrates that the supplier can consistently manufacture components that meet the required specifications and are safe for use in the intended application.

Why Perform Production Part Approval Process (PPAP)
The Production Part Approval Process (PPAP) ensures the product meets the customer's requirements and specifications before releasing it into production. PPAP is a critical tool for the automotive and other industries where quality control is paramount. By performing PPAP, manufacturers can identify and resolve issues early in production, reducing the risk of costly mistakes and potential recalls.
Many automotive manufacturers and suppliers require PPAP as part of their quality management systems. Failure to comply with PPAP requirements can lead to rejected claims, production delays, and even the loss of business. Also, learn about the Five s's (5s) Of Lean.
Performing PPAP also helps ensure that suppliers have the necessary resources, expertise, and processes to produce high-quality parts. It can help identify potential risks and issues early in the development process, allowing for corrective actions to prevent them from occurring later in production
When to Perform Production Part Approval Process (PPAP)
The Production Part Approval Process (PPAP) is typically performed in the early stages of production before mass production begins. This ensures that potential issues with the product design or manufacturing process are identified and resolved before large quantities of the product are produced
PPAP should be performed whenever a new part or a change to an existing part requires approval before production. This can be due to various reasons, such as a change in design, materials, suppliers, or manufacturing processes.
PPAP is also commonly required by customers, particularly in industries such as automotive, aerospace, and medical devices, where there are strict quality and safety standards. Customers may need PPAP to ensure their suppliers have the necessary processes and controls to consistently produce high-quality parts
In addition, PPAP may be required by regulatory bodies, such as the FDA or EPA, to ensure compliance with industry-specific regulations and standards. You can avail of Quality Inspection Services In Mexico for your convenience.
How to Perform Production Part Approval Process (PPAP)
The Production Part Approval Process (PPAP) is a vital process that ensures that parts produced for automotive and other industries meet customer specifications. This process is critical in the automotive industry, where quality control is essential to ensure customer safety. The PPAP process is a comprehensive method suppliers use to validate and verify their production processes and ensure that parts meet the customers' requirements.

PPAP Levels of Submission
The PPAP process consists of five levels of submission, with each level building upon the previous level's requirements. These levels include:
Level 1: Part Submission Warrant (PSW) - This level requires the supplier to submit the PSW, which verifies that the part meets the customer's specifications and includes a statement of the supplier's responsibility
Level 2: PSW with Product Samples - The supplier must submit the PSW and provide product samples for validation.
Level 3: PSW with Product Samples and Supporting Data - This level requires the supplier to submit the PSW, product samples, and supporting data such as engineering drawings, test results, and statistical process control data.
Level 4: PSW with Product Samples and Complete Supporting Data - This level requires the supplier to submit the PSW, product samples, complete supporting data, and a preliminary process capability study.
Level 5: PSW with Product Samples and Complete Supporting Data Available for Review - This level requires the supplier to submit the PSW, product samples, complete supporting data, and process control plan.
Elements of PPAP
The PPAP process consists of 18 elements that suppliers must submit to validate their production processes. These elements include:
- Design Records
- Engineering Change Documents
- Customer Engineering Approval
- Engineering Approval of Supplier
- Process Flow Diagrams
- Process Failure Mode and Effects Analysis (PFMEA)
- Control Plan
- Measurement System Analysis (MSA)
- Dimensional Results
- Material Performance Test Results
- Initial Process Studies
- Qualified Laboratory Documentation
- Appearance Approval Report (AAR)
- Sample Production Parts
- Master Sample
- Checking Aids
- Customer-Specific Requirements
- Part Submission Warrant (PSW)
