PPAP is one of the five tools of the TS16949 quality management system and is used for quality control in the production process of automotive vehicles or parts. PPAP is not simply the submission and approval of documents, but rather a complete process to confirm whether the supplier is capable of producing qualified products in bulk and with stability. This article revolves around the following five steps to briefly explain the main tasks, inputs, and outputs of each stage of the PPAP process, and strives to identify and solve as many problems as possible before part production ......

Non-destructive testing (NDT) refers to inspection techniques used to investigate the interior of an object without damaging it. There are various methods of NDT, each with its own strengths and weaknesses. Therefore, when conducting quality inspections, appropriate methods must be combined based on factors such as the material of the manufactured product. In this article, we will explain the basics of NDT, including the objectives and differences in methods. Inspecting products is an important process for those responsible for manufacturing to confirm that quality is being maint......

In factories that use line production methods to manufacture products, it is essential to quickly confirm the quality of the products to avoid continuing to produce defective items. Inline inspection machines are indispensable devices for product inspection during production that can inspect the appearance defects, optical characteristics, and shapes such as concave-convex while producing the product. This article explains the mechanism of inline inspection and the differences from offline inspection, as well as provides examples of inline inspection equipment and specific products. ......

Both product testing and product inspection are important aspects of quality control, they serve different purposes and are performed at different stages. Let’s take a look at the differences between production inspection and testing, as well as tips for choosing between them. Differences Between Product Testing and Product Inspection Product testing and product inspection are both important aspects of quality control in manufacturing, but there are some key differences between the two: Purpose: The purpose of product testing is to evaluate the performance and charact......

Performing dimensional inspection requires suitable tools to get the best results. What tools are commonly used in dimensional inspection and what are the main types of methods applied? What Tools are Used in Dimensional Inspection? Dimensional inspection tools are used to measure the physical characteristics of a part or product to ensure that it meets the required specifications. There are many different types of dimensional inspection tools, including: Calipers: used to measure the distance between two points on a part or product.

Analyzing the differences between TQM and Lean Six Sigma, TQM is a process developed after the quality inspection phase and the statistical quality control phase (SQC) that emphasizes the involvement of all employees in focusing on the generation, formation, and realization of all quality. Lean Six Sigma is built on many of the commonly used statistical process control tools and TQM. It enhances the process through more demanding statistical analysis and by providing more rigorous problem-solving (DMAIC). Creative and analytical thinking concept.

So what exactly is a product audit, what is its role in quality inspection, and how can you effectively perform a product audit? In this article, we will bring you a detailed explanation. What is Product Audit？ Product Audit is the activity of independently checking and evaluating the quality of product suitability from t......

On the purchasing side, it is important to clarify what you want suppliers to implement as a minimum. The auditee side also has a great opportunity to learn the level of requirements on the supplier’s side. Process quality audit is the focus of the internal quality audit, the purpose of which is to verify whether the factors affecting the production process and its control methods meet the requirements of process control and process capability, to identify existing problems in a timely manner, and to take effective corrective or preventive measures to improve and enhance to......
