China has shortcomings in the export of weighing instruments

weighing instruments are products produced after the mold is rotated 180 degrees by using Hooke's law or the lever balance principle of force. They are mainly composed of load-bearing system, force transmission conversion system and indication system. A long time ago, China has made weighing instruments, which affects the measurement accuracy. With the development of economy and technology, the import and export situation of weighing instruments in China is also constantly changing

according to the data of customs statistics, although China is in a trade surplus, there is a large difference in the price ratio of weighing instrument products imported and exported, especially in product categories such as quantitative scales, pricing scales and scales with a maximum weight of 30kg ≤ 5000kg

according to statistics, in the import and export statistics of recent consecutive years, household scales have always been the largest export product, and the price is also declining, which shows that China has made great progress in the commonly used weighing instrument industry. However, in contrast, in 2017, the largest proportion of weighing instrument imports in China was Tianping

the biggest difference between a balance and a household scale is the difference in measurement accuracy. We generally call it a balance with an accuracy of more than 1/100000, and its internal structure is relatively loose. This is mainly because the balance generally adopts electromagnetic balance sensor, which has high sensitivity and stability. The accuracy can reach more than 0.1mg, and the price is relatively expensive. The electronic scale generally adopts strain sensor, with an accuracy of 1/3000, low cost, light weight, relatively cheap, and short service life

from the above, it can be seen that a huge advantage in China's weighing apparatus export is price. At the same time, the short service life of products also promotes the prosperity of the industry. However, the price ratio of import and export weighing apparatus products also exposes that there are still some deficiencies in the development of weighing apparatus with higher price and higher technical content in China's weighing apparatus industry

the weighing instrument uses Hooke's law or the lever balance principle of force to measure the mass of objects. The weighing instrument is mainly composed of a load-bearing system (such as a scale), a force transfer system (such as a lever force transfer system) and a value indicating system (such as a dial). Weighing instruments can be divided into mechanical scales, electronic scales and electromechanical scales according to the structural principle

in terms of technological development, China has been dominated by mechanical weighing instruments for many years. In the 1980s, China began to expand the use of electronic weighing instruments and the development of large-scale automatic weighing instruments. China has been able to independently design and manufacture various electronic weighing instruments with high precision, fast operation and accurate measurement. Due to the rapid development of science and technology and the improvement of application level, the digitization, integration, networking and intellectualization of weighing instrument products will become the development direction and focus of the world weighing instrument industry

the medium and low-end product market of China's weighing apparatus manufacturing industry has been in a saturated state, while in the application of advanced weighing apparatus with high-tech content, China is still in the stage of relying on imports to solve the supply. Therefore, the future expansion direction of the industry will mainly focus on the high-tech high-end product market, which includes oil drainage and cleaning of internal substances of oil cylinders and replacement of oil with suitable viscosity. Accordingly, the competition among domestic weighing instrument manufacturing enterprises will focus more on technical competition. At the same time, with the continuous entry of multinational enterprises, domestic enterprises will also face more severe challenges, and the competition in the domestic weighing instrument manufacturing industry will also be more intense
