Energy saving technology of injection molding machine: How to reduce energy consumption through technical means

With the continuous advancement of the industrialization process, injection molding machine as an indispensable equipment in the manufacturing industry, its energy consumption problem has become increasingly prominent. High energy consumption not only increases the operating costs of enterprises, but also causes a certain pressure on the environment. Therefore, exploring the energy-saving technology of injection molding machine and reducing energy consumption through technical means has become an urgent problem for the current manufacturing industry. We will discuss the implementation strategy and effect of energy-saving technology of injection molding machine from many aspects.

1、Analysis of energy consumption of injection molding machine

1.1、Energy consumption composition

The energy consumption of injection molding machine is mainly composed of motor, heating system, cooling system and hydraulic system. Among them, the energy consumption of motors and heating systems accounts for most of the total energy consumption. The motor drives the screw rotation to plasticize and inject the plastic raw material into the mold, while the heating system is responsible for heating the plastic raw material to the appropriate temperature. Although the cooling system and hydraulic system consume less energy, they are also an important part of the energy consumption of the injection molding machine.

1.2、Influencing factors of energy consumption

The energy consumption of injection molding machine is affected by many factors, including the design structure of the machine, operating parameters, maintenance status and the skill level of the operator. Improper design of structure leads to increased energy loss. Improper setting of operating parameters will cause energy waste; Less maintenance will affect the efficiency of the equipment; Inadequate operator skills can lead to problems such as breakdowns and downtime during production, which in turn increases energy consumption.

2.3、Strengthen maintenance

Regular maintenance of the injection molding machine can ensure the normal operation and high efficiency of the equipment. For example, clean heating and cooling systems can maintain good heat transfer; Replacing worn parts can reduce energy loss; Regular inspection and maintenance of the hydraulic system can ensure its normal operation and high performance.

2.4、Improve operator skills

Improving the skill level of the operator can effectively reduce the energy consumption of the injection molding machine. Through training and education, the operator can master the correct operation methods and skills, adjust the operating parameters according to different production needs, and avoid unnecessary energy waste.
