Current Status and Rapid Development Reasons of Foreign Weighing Sensor Technology
The technology and manufacturing process of weighing sensors used in industrial and commercial electronic scales are led by famous manufacturing companies from industrial developed countries such as the United States and Germany, which are at the forefront of the international market. China's relatively large-scale weighing sensor manufacturing companies are in a position of market challengers or followers. The research and development center for weighing sensors used in home electronic scales is in China, specifically in Shenzhen. Manufacturing technology, process level, product quality, and annual output have been improving year by year.
Today’s competition in international market weighing sensor technology mainly focuses on the competition of product accuracy, stability, and reliability; competition of manufacturing technology and processes; and the competition of applying high technologies to develop new products and proprietary intellectual property products. All weighing sensor manufacturing enterprises are striving to cultivate their core competitive technologies and create core competitive products.
From analyzing the products exhibited at international weighing industry exhibitions over the past few years and examining multiple leading companies' products, it can be concluded that these companies share common pursuits: better materials for elastic bodies; stricter technical requirements and environmental stress screening for strain gauges and compensation components; more refined manufacturing processes; more complete circuit compensation processes; and higher quality appearance.
The accuracy, stability, and reliability of weighing sensors are important quality indicators and also issues of utmost concern to users. In response, these companies conduct numerous studies and experiments in structural design, manufacturing processes, circuit compensation and adjustment, and stability treatment, achieving significant progress. The main achievements include:
(1) Introducing computer simulation technology for dynamic simulation and dynamics analysis during the structural design and calculation process; introducing computer virtual technology in the process design to simulate and inspect elastic body production processes.
(2) Incorporating advanced manufacturing technology in elastic body processing, transforming rigid manufacturing into flexible manufacturing. Widely adopting machining centers, flexible manufacturing units, and flexible manufacturing systems.
(3) Minimizing manual operations and human control throughout the production process, increasing semi-automatic and automatic controls, automatic inspection procedures, and adopting computer network technology in production processes.
(4) Improving and innovating process equipment to achieve efficient intelligent circuit compensation, establishing fully automatic rapid detection systems, enhancing the success rate of C3 grade products and the random inspection pass rate of mass-produced products.
(5) Transferring advanced stabilization treatment technologies and equipment, implementing new vibration aging or resonance aging processes to improve the long-term stability and working reliability of weighing sensors.
(6) Applying high technologies to develop new products and proprietary intellectual property products, strengthening core competitiveness. Leading companies in the international market all possess their own core competitive technologies, processes, and products, such as "O creep" weighing sensors with positive and negative creep bridges; beryllium bronze dynamic weighing sensors; integrated and separated digital intelligent weighing sensors; high-accuracy stainless steel 3-column and 4-column high-temperature weighing sensors; and "plug-and-play" type new-style weighing modules designed in modular form.
Characteristics and reasons for the rapid development of foreign weighing sensor technology:
(1) Emphasizing research on basic technologies, basic processes, and common key technologies, ensuring concurrent basic research and preliminary research; concurrent common key technology research and applied technology research; and concurrent typical product development and product engineering. Ensuring that basic technologies and processes (strain gauges, strain adhesives, compensation components, protective and sealing materials, etc.) remain consistently world-leading.
(2) Valuing infrastructure construction and research and application of manufacturing technology and processes. Equipping with excellent process equipment and testing instruments, especially intelligent process equipment, ensuring the most advanced process equipment.
(3) Targeting the development trends and strategic frontiers of global weighing sensor technology to determine research topics and product development directions. Emphasizing the development of new products and proprietary intellectual property products to strengthen core competitiveness. Their standards for technological innovation and new product development are: having high technical foresight, advanced processes, market diffusion, and value-added benefits. Keeping technology and processes always at the world's forefront.
(4) Valuing the reliability design, control, and management of weighing sensors, strictly controlling design compliance and process reliability, striving to achieve a hundred percent process fulfillment rate.
(5) Valuing market competition, strengthening market research and analysis, and quickly responding to the market. In the 21st century, market competition focuses on market response speed, based on improving and innovating products.
(6) Valuing the study of relevant regulations and procedures, comprehensively understanding and seriously implementing them, ensuring that every produced product meets requirements.
Because of this, foreign weighing sensors come in a wide variety of types and specifications, including alloy steel, aluminum alloy, stainless steel, and beryllium bronze products; underwater, downhole measurement, pressure-resistant explosion-proof, radiation-resistant, corrosion-resistant products; micro and ultra-large range; multi-weighing and dynamic weighing; integrated and modular structures available for user selection. Both internal and external product quality are equally emphasized, with significant improvements in recent years in appearance quality. Most products no longer require painting but instead use bright or matte chemical nickel plating, chrome plating, baking paint, spraying plastic, ceramic anodization, and stainless steel finishes. Some products even incorporate humanized design elements in their appearance.
