It has been more than 60 years since the production of the first traditional band heater. The United States, Germany, and Japan, as the traditional technology powerhouses of injection molding machines, still maintain a leading position in the market. China is a rising star in the manufacturing industry. According to incomplete statistics, there are more than 60 manufacturing companies. China's injection molding machine output accounts for 2/3 of the global injection molding machine output. Therefore, China's injection molding machine supporting enterprises have developed rapidly. Among them, the leading enterprises in the industry have been born in castings, screws, motors, servo drives, manipulators, hopper dryers and other industries, and have developed into a global plastic machine supporting supplier. Shini dryer is representative. Only the heating coil part of the injection molding machine, there is currently no leading domestic company that has formed an advantage, forming a competitive situation where a hundred schools of thought are contending and a hundred flowers blooming. For now, the partial industry of heating coils is breaking the chaotic market due to the emergence of infrared energy-saving heating coils. Pattern, gradually forming industry leaders and advantageous enterprises. In view of this, the author, who has many years of experience in the heating circle industry, makes a horizontal comparison with the current mainstream plastic machine heating circle in the Chinese market, and looks at the current market development direction from a development perspective. The world is currently taking the Paris Climate Summit as an opportunity and a unified carbon trading market is being established in China. Therefore, in order to comply with the country’s development of a resource-saving and environment-friendly society, Chinese-made injection molding machines are vigorously implementing a green development strategy and firmly grasping Energy-saving and environmentally friendly products have become a hot market opportunity. Injection molding machine heater manufacturers are also accelerating the pace of traditional technology transformation and upgrading, and continue to adopt new energy-saving and consumption-reducing technologies, new products, new processes, and new materials to meet the needs of various manufacturers. Low energy consumption requirements.
