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. They are commonly used to measure the di......

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.

Product audits can identify discrepancies with customer requirements and directly determine the impact of this process. Through the identified deviations, the process causing the deviation can be focused on the investigation, analysis, and corrective action. 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......

In most product standards, the inspection is unified for the type test (routine inspection) and factory inspection (acceptance inspection) two categories. What is the difference between them? Generally speaking, the type test is a comprehensive inspection of the product quality indicators to assess whether the product quality is fully in line with the standard and whether it achieves the full design quality requirements. Factory quality inspection is the formal production of products in the delivery of the final inspection that must be carried out to check the quality of the prod......

3D scanning is an effective method to measure and inspect manufactured parts and products, how is 3D laser scanning used in quality control and how accurate is it? What is 3D Laser Scanning? 3D laser scanning is a non-contact, non-destructive technology used to capture the shape, size, and position of objects in a three-dimensional digital format. It uses a laser scanner that emits a beam of light that scans the surface of an object, and the reflected laser light is then captured by a sensor to create a point cloud. The point cloud is a collection of millions of individual poin......

The pre-shipment inspection is important in the quality management of exporting goods. What are the different ways of PSI inspection and who performs that? Different Methods of Pre-Shipment Inspection Pre-shipment inspection (PSI) is a quality control process that helps importers ensure that the goods they are importing meet their quality standards and specifications. There are five methods of pre-shipment inspection, including:1) Full inspection: In this method, the entire shipment is inspected to ensure that it meets the importer’s quality requirements. This involves ch......
