High Speed Energy Saving Injection Molding Machine For Plastic Baby Bathtub

Traditional injection moulding machine uses asynchronous motor (squirrel cage) to provide power. The constant speed asynchronous motor converts electric energy into kinetic energy. The output "useful" kinetic energy is only about 90% of the input electric energy (when full load), while the others become thermal energy. Therefore, the motor will bring its own fan to take away the heat energy.

On the one hand, the induction motor drives the quantitative pump to output constant flow; on the other hand, the flow requirements of each action in the injection cycle, such as opening and closing die, ejection and so on, are different, and the unnecessary flow will flow back to the tank under the set pressure at that time. The slower the action is, or the greater the set pressure is, the more energy will be wasted, and the waste energy will become heat energy, which will increase the oil temperature. Therefore, generally speaking, the farther the action speed is from the full speed, the longer the time is, and the greater the pressure is, the greater the potential energy-saving range.
