How to save electricity for injection molding machine

In fact, the power consumption of the injection molding machine has nothing to do with the price of the injection molding machine. Think about it. The injection molding machine basically works all day. Firstly, the workload is relatively large, and the corresponding power consumption will increase over time. This is actually a normal phenomenon. However, since many users have asked us how to save power for the injection molding machine, here we have sorted out some tips that can help the injection molding machine save power, hoping it can help you.

1、 Features of oil circuit controlled by proportional valve:

The oil pump motor runs at full speed and high load after operation, and then sets the pressure and flow required for each stage through the proportional valve. In a production cycle of the injection molding machine, only the motor load in the high-pressure mold locking and glue melting stage is large, and the motor load in other working stages is generally small. The oil pump motor in other stages provides constant flow at constant speed, Excess hydraulic oil flows back through the overflow valve, resulting in unnecessary waste.

2、 Features of oil circuit controlled by on-off valve:

The power of the oil pump motor is equipped according to the large load during its operation. After the operation of the oil pump motor, the pressure and flow are not set. When the mold locking, glue injection, glue melting, pressure maintaining, cooling and mold opening work in each stage, the corresponding directional on-off valve opens in the oil circuit, works at full flow and the overflow valve closes. During cooling and discharging, the directional on-off valve of each stage is closed, the overflow valve is opened, and all reflux occurs, resulting in waste.

3、 Power saving analysis of injection molding machine:

In the process of cooling and discharging, the load of oil pressure driven equipment represented by injection molding machine is almost zero, and the cooling and discharging time accounts for 30-60% of the whole cycle. According to previous work experience, in the injection molding machine, the energy loss caused by cooling and discharge overflow is as high as 30% – 65%. The power consumption of injection pump motor accounts for 60% – 75% of the power consumption of the whole equipment, which has great energy-saving potential

Before using the injection molding machine, first read the price book of vertical Shanxi injection molding machine carefully, so as to ensure your understanding of the whole operation process. After reading the whole instructions for use, it is necessary to check the normality of the machinery, and the check of the sensitivity of the switch is particularly important to avoid emergency accidents.

Here are some tips on how to save power during the use of injection molding machine. I will continue to update them later. I hope the content shared today can help you better understand the knowledge of injection molding machine.
