In research and development, riding the waves of injection molding machine as the emergence of many new products. All-electric injection molding machine is the product of one of the innovative technology. Packing it in, cooling and idling conditions maintain a low speed, so as to achieve energy-saving, the purpose of noise reduction, but its short life. And to the traditional hydraulic injection molding machine market impact is even greater set of hydraulic and electric drive in one of the electro-hydraulic injection molding machine. It combines the entire hydraulic injection molding machine and all the high-performance electric energy-saving advantages, drive systems can improve efficiency and reduce energy losses, hydraulic injection molding machine to accelerate the development and application of energy-saving technologies.
