Product Description
We sell the small plastic injection molding machine in 3 types, fixed pump type, variable energy-saving type and servo energy saving type. Here we will introduce the servo energy saving injection molding machine. This type machine does not have extra energy consumption due to output volume changes according to the load, servo motor does not work during cooling stage. 0 consumption. Compare with traditional injection moulding machine can save electricity 40-80%.
Injection molding machine Feature
- Pressure response fast, quickly up to 0.05s
- Compared to traditional injection molding machine, the control system to respond will be 2-3 times faster.
- High response speed, shorten cycle times, improve production efficiency.
- Products repeat accuracy can be increased to more than 5‰, fully able to meet the requirements of ultra-precision injection molding.
