Metal castings are a type of molded articles, how to conduct effective quality inspection on castings? Here are some testing methods to ensure high quality castings. How to Inspect Castings without Damage or Destruction 1) Liquid penetrant testLiquid penetrant testing is used to check various opening defects on the surface of castings, such as surface cracks, surface pinholes, and other defects that are difficult to find with the naked eye. The commonly used penetrant inspection is color inspection. This method is to correct or spray-colored (usually red) liquid (penetrant) wit......

How to precisely measure the dimensional accuracy of machining parts? Here we’ll present five methods of part dimensional inspection. 5 Ways to Measure the Dimensional Accuracy of Workpieces in Machining 1) Trial cutTrial cutting entails trial cutting, measuring, correction, and recutting until the requisite dimensional precision is achieved. For example, the box hole system’s trial boring. That is, initially attempt to cut a small portion of the machined surface, measure the size acquired from the test cut, modify the position of the tool’s cutting edge relat......

Inspection of welds is difficult and it takes time to train inspectors. If you increase the number of inspectors in order to train them, inspection results will vary and quality will not be stable. In addition, a lot of time is required for inspection, and production cannot keep up. Therefore, if welding inspection equipment is introduced, quality inspections can be performed faster and more accurately than human inspections. In addition, it is possible to inspect during welding and inside the weld, which stabilizes and improves quality. In this article, we will explain the types ......

Dimensional inspection to confirm that products and parts are finished to the specified dimensions is an important process in manufacturing. In the past, human visual inspection was the mainstream, but it was time-consuming and time-consuming, and inspection errors occurred. Currently, automation using dimensional inspection equipment is progressing, and it is becoming possible to realize dimensional inspection efficiently and without mistakes. In this column, we will introduce the mechanism and merits of dimensional inspection by dimensional inspection equipment, and points to consi......

An adequate internal audit management offers security and effectiveness for the evaluated Management System, for example, Quality Management, a standardized system with greater implementation at international level. Let us remember that the audit has among its objectives to identify problems that prevent the system from meeting the needs of stakeholders and the achievement of corporate objectives. That is why internal auditing is the engine that drives the continuous improvement of the system. But this does not mean that performing many audits will lead to much more improvement. It i......

Measurement System Analysis (MSA) is one of the five tools of quality management, why it is applied, and what statistical characteristics it has? What is Measurement System Analysis (MSA)? A measurement system is a collection of instruments or measuring tools, standards, operations, fixtures, software, personnel, environment, and assumptions used for quantitative measurement or qualitative evaluation of the measured characteristics. The whole process used to obtain the measurement results is called the measurement process or measurement system. Measurement System Analysis re......

To strengthen their advantages in the market, manufacturers should not only continuously improve product quality but also constantly improve the efficiency of production. The automatic and intelligent surface defect detection method is helpful. Technical Difficulties & Challenges in Surface Detect Detection 1) Difficulties caused by defectsThe complexity of different types of defects and the great difference between the same type of defects bring a great difficulty to detection. The complexity of different defects is mainly reflected in three aspects. First of all, there ar......

An automobile is a hybrid complex system that is composed of a huge number of parts, each playing its own unique role in the whole car. However, similar to other components, quality control, and inspection is essential for the car parts after manufacturing to ensure their quality and function. So let’s see what automotive parts need to be inspected and what tests are included. Types of Automotive Parts The quality of car parts matters directly to safety. It is necessary to ensure their performance. The auto parts are mainly composed of the following eight sections. Aut......
