The energy saving of injection molding machine can be divided into two parts: one is the power part and the other is the heating part.

The energy saving of injection molding machine can be divided into two parts: one is the power part and the other is the heating part. Power part of the energy saving: most of the use of frequency converter, energy saving is through the saving of the motor of the remaining energy consumption, such as the actual power of the motor is 50Hz, and you actually only need 30Hz in production is enough to produce, those excess energy will be wasted, the frequency converter is to change the power output of the motor to achieve the effect of energy saving. Heating part of the energy-saving: heating part of the energy-saving mostly electromagnetic heaters are used to save energy, the energy saving rate is about 30% -70% of the old resistance circle. Compared with resistance heating, electromagnetic heaters have more than one layer of insulation, heat utilization increased. Compared with resistance heating, electromagnetic heaters act directly on the material tube heating, reducing the heat transfer heat loss. Compared with resistance heating, electromagnetic heater heating speed is faster than a quarter, reducing the heating time. Compared with resistance heating, electromagnetic heater heating speed, productivity is improved, so that the motor is in a saturated state, so that it reduces the high power low demand caused by power loss. The above four points are flying as electromagnetic heaters, why can be in the injection molding machine energy saving up to 30% -70% of the reason!

The working principle of the injection molding machine

The working principle of the injection molding machine is similar to that of the syringe used for injection, it is with the help of the thrust of the screw (or plunger), the plasticized molten state (i.e., viscous flow state) of the plastic is injected into the closed mold cavity, and then the products are obtained through the process of curing and shaping. Injection molding is a cyclic process, each cycle mainly includes: dosing – melting and plasticizing – pressure injection – mold cooling – open the mold to take parts. After taking out the plastic parts and then close the mold for the next cycle. Injection molding machine operation project: injection molding machine operation project includes control keyboard operation, electrical control system operation and hydraulic system operation in three aspects. The injection process action, feeding action, injection pressure, injection speed, ejection type selection, barrel temperature monitoring, injection pressure and back pressure pressure adjustment. General screw injection molding machine molding process is: first of all, granular or powdered plastic into the barrel, and through the rotation of the screw and the outer wall of the barrel heating so that the plastic becomes molten, and then the machine for the mold and the injection seat forward, so that the nozzle is close to the mold’s gate channel, and then to the injection cylinder through the pressure of the oil, so that the screw forward so that a very high pressure and high speed will be injected into the molten material at a
