Scales in weighing instruments are widely used in industries, agriculture, commerce, scientific research, medical and health departments. Weighing instruments use the principle of lever balance of Hooke's law or force to measure the mass of objects. The scale is mainly composed of a load-bearing system (such as a weighing pan), a force transmission conversion system (such as a lever force transmission system) and an indication system (such as a dial). According to the structural principle, the scales can be divided into three categories: mechanical scales, electronic scales, and electromechanical combined scales. Mechanical scales are divided into lever scales and spring scales. According to the measurement method, the scale is divided into non-automatic scales and automatic scales. Its main varieties include balances, bar scales, case scales, platform scales, ground scales, floor scales, track scales, belt scales, postal scales, crane scales, batching scales and bag scales. The focus of the development of the scale is the electronic scale. The use of modern technologies such as program control, group control, teleprinting, and screen display makes the instrument fully functional and efficient. An instrument that measures the mass of an object by measuring the weight of the object (the amount of gravity it receives). Some scales are customarily called scales. Scales are widely used in industrial, agricultural, commercial, scientific research, medical and health departments.

China's weighing industry is a traditional industry with a long history of development and an important basic industry. After the reform and opening up, China's weighing instrument industry has developed rapidly. The management system, industry structure, product structure, technical level of the weighing instrument industry and its position in the national economy are even more varied. According to the statistics of “ 2013-2017 China's Weighing Apparatus Manufacturing Industry Sales and Demand Forecast and Transformation and Upgrading Analysis Report ”, as of the end of 2011, China's scale (annual income of 20 million yuan) has 142 weighing and weighing enterprises, including 83 private enterprises. 32 enterprises. In 2011, the sales revenue was 16.072 billion yuan, a year-on-year increase of 29.29%; the total profit was 1.527 billion yuan, a year-on-year increase of 32.13%.

In terms of technological development, China has been focusing on mechanical weighing instruments for many years. In the 1980s, it 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 high precision, fast operation and measurement. Accurate electronic weighing instruments. Due to the rapid development of science and technology and the improvement of application level, the digitization, integration, networking and intelligence of weighing instruments will become the development direction and focus of the world weighing instrument industry.

The middle and low-end products market of China's weighing instrument manufacturing industry is already in a saturated state. In the application of high-tech advanced weighing instruments, China is still in the stage of relying on import to solve supply. Therefore, the future expansion of the industry is mainly focused on high-tech content. High-end product market. Correspondingly, competition among domestic weighing instrument manufacturers will focus more on technical competition. At the same time, with the continuous entry of multinational companies, domestic enterprises will also face more severe challenges, and the competition in the domestic scale manufacturing industry will become more intense.

2011-2020 is an important period for China to implement the sustainable development strategy of the national economy, promote the development of circular economy, take a new road to industrialization, and lay a foundation for building a resource-saving and environment-friendly society. During the "Twelfth Five-Year Plan" period, China's national economy will continue to develop, with the development of animal flow, machinery, chemicals, ports and other industries, which will bring good opportunities for the development of the weighing instrument manufacturing industry. Qianjin.com expects the scale instrument manufacturing industry in 2015. The sales scale will exceed 25 billion yuan.
