Could this plastic become a detection marvel? Decode the core material breakthrough of high - frequeIssuing time:2025-05-14 10:33 Overview of Industrial Nondestructive Testing Technology definition Nondestructive testing (NDT) is a technology that uses modern equipment to conduct qualitative and quantitative analysis of internal and surface defects of test pieces by detecting changes in physical/chemical responses such as heat, sound, light, electricity, and magnetism caused by abnormal internal structure or defects of materials without destroying the performance and internal structure of the tested object. As the "quality guardian" of modern industry, its development level directly reflects the national industrial competitiveness. Technical features Non-destructive: Maintain the integrity of the object being inspected Full life cycle coverage: from manufacturing to service and end-of-life Multi-dimensional detection: can identify key parameters such as defect type, size, distribution, etc.
Ultrasonic testing Way A method of inspecting part defects by using the ultrasonic energy to penetrate the deepest part of metal composite materials and produce reflection characteristics at the edge of the page when passing from one cross section to another. Rationale The beam antenna passes from the surface of the part through the camera to the internal structure of the metal material. When it encounters a defect and the bottom edge of the part, it generates reflected waves respectively, producing a pulse waveform on the screen. The defect position and size are determined based on this pulse waveform. advantage Ultrasonic flaw detection has the characteristics of higher detection sensitivity, shorter cycle time, lower cost, more convenience, higher efficiency and no harm to human health than X-ray flaw detection. shortcoming The working surface must be smooth, and only experienced inspectors can identify the defect type. The defects are not intuitive. Ultrasonic testing is suitable for the inspection of parts with relatively large thickness.
Market drivers and technological evolution Demand growth engine In recent years, with the continuous improvement of the national economy and the deepening of industrial restructuring, traditional industries have gradually completed transformation and upgrading and developed towards higher-end development; at the same time, resources such as human resources and capital have gathered in advanced manufacturing, directly stimulating the rapid development of key industries such as aerospace, automobiles, high-speed rail, and rail transportation. New materials, new structures, and new processes continue to emerge, thereby promoting the growth of demand for ultrasonic testing equipment. For example, with the development of new energy vehicles and consumer electronics, new market demand has been formed for non-destructive testing of power batteries and components. On the other hand, the continuous development of downstream application fields will bring objective demand growth for testing instruments, and also put forward higher requirements for the performance, accuracy, and efficiency of non-destructive testing equipment, thus becoming the source of technology upgrades and product iterations in the non-destructive testing industry. The two complement and promote each other. Market size forecast According to statistics, the scale of my country's non-destructive testing service market has exceeded 300 billion yuan, and annual instrument sales have exceeded 20 billion yuan. As the manufacturing industry transforms towards high-end, intelligent and green, the demand for non-destructive testing technology in the fields of new energy, semiconductor and electronic manufacturing, aerospace and defense, rail transportation and infrastructure, life sciences, etc. has surged. Domestic equipment manufacturers are breaking the foreign monopoly through technological innovation and becoming the backbone of the industry's development.
