China's rapid development of electric tool industry, export earnings are very low

In recent years, China's electric tool industry has developed rapidly in the international market, while foreign exchange earned from export products is very low. The majority of the products exported by China's power tools are Dingpai and Neutral, and basically they are sample-processing and do not have their own brands. On the other hand, foreign trade companies and export product manufacturers are pushing down prices and competing for low prices. As the prices of many export products have been declining year by year, the economic benefits of export companies have been seriously affected, and the industry's efficiency has been declining year by year. In addition, the products exported by China are almost all DIY tools and cannot be used in production lines and industries. Therefore, the export of these products cannot be sold at a good price.

The current users have further improved the product quality requirements of electric tools, especially the indicators such as product efficiency, weight, and life expectancy. Taking the construction industry as an example, the quality problems of domestic electric tools are mainly reflected in the following: electric hammers are prone to heat, and the continuous working time is short; electric hammers have small impact force and large vibrations; the operator must use pressure to advance deeply; the drill bit is easy to wear and breaks easily. Wait. Therefore, in recent years, imported electric tools in the construction industry have greatly impacted the domestic market.

At the same time, most of our electric tools do not meet the requirements of environmental protection. At present, new products developed in China should meet the requirements of the new radio interference standard (commonly known as EMC), and the level of EMC technology should be further improved. At the same time, new materials and new technologies should be used to reduce product noise. For example, development of rare earth permanent magnet materials will not only improve efficiency, but also reduce noise and protect the environment, but also improve product performance. In addition, China's electric tools only impact electric drills, electric drills, hammers and other few varieties of electronic speed control functions, most of them are single-speed products, can not meet the user's product level requirements.

In general, China's power tools have a large gap between the product technology level and foreign counterparts, mainly due to poor product appearance, monotonous appearance, unstable quality, high-frequency screams, and low unit weight output. Electromagnetic compatibility does not meet the requirements. For example, in terms of unit weight output, current drills are about 30 to 50 watts/kg lower than foreign ones; angle grinders are about 30 to 100 watts/kg lower; and impact drills are about 30 to 80 watts/kg lower.

The insulation structure of our country's power tool products is E-class. Now we have begun to study the insulation material of B-series series-excited motors to improve the insulation class. Although computer-aided design (CAD) has been applied in some enterprises, it has not yet been popularized in the industry. The research on ergonomics, the application of electronic technology, the study of large-capacity rechargeable batteries, the development of fast chargers, the study of the selection of insulation structures, the study of the selection of working parameters, the study of transmission structures and the design of moldings were carried out earlier in the world. And has been widely used in power tools.

In terms of new product development, most domestic enterprises are in the stage of experience design, prototype mapping, and the new product development cycle is long, while foreign countries have realized paperless design, commonly used computer-aided design, auxiliary graphics, auxiliary manufacturing (CAM), and auxiliary tests. (CAT), the new product development cycle is only 2 to 3 months.
