How to reduce the energy consumption of injection molding?

The injection molding machine is a major energy consumer in the injection molding workshop, and the energy consumption is mainly for the motor and heating.
1. Select the appropriate injection molding machine according to the product characteristics. The injection molding process of "big horse pulling car" often means a lot of energy waste.
2. The all-electric injection molding machine and hybrid injection molding machine are selected, which have excellent energy-saving effect, and can save 20-80% energy.
3. Using new heating technologies, such as electromagnetic induction heating, infrared heating, etc., can achieve 20-70% energy saving in heating.
4. Take effective thermal insulation measures for heating and cooling systems to reduce heat and cold losses.
5. Keep the transmission parts of the equipment well lubricated and reduce the increase of energy consumption caused by increased friction or unstable operation of the equipment.
6. Select low compression hydraulic oil to reduce the waste of working energy of hydraulic system.
7. The use of parallel action, multi-cavity injection molding, multi-component injection molding and other processing technologies can significantly save energy.
8. The traditional mechanical hydraulic injection molding machine also has a variety of energy saving drive systems, which can significantly save energy instead of the traditional quantitative pump mechanical hydraulic injection molding machine.
9. The heating and cooling pipes shall be regularly maintained to ensure that there are no impurities, scale blockage and other phenomena inside the pipes, so as to achieve the designed heating and cooling efficiency.
10. Ensure that the injection molding machine is in good working condition. Unstable processing may lead to defective products and increase energy consumption.
11. Ensure that the equipment used is suitable for the products processed, such as PVC processing often requires special screw.
3、 Injection mold
The mold structure and mold condition often have a significant impact on the injection molding cycle and processing energy consumption.
1. Reasonable mold design, including runner design, gate form, cavity number, heating and cooling channels, can help reduce energy consumption.
2. The use of hot runner mold can not only save materials and reduce energy consumption of material recovery, but also has significant energy-saving effect in the molding process itself.
3. Profiling rapid cooling and rapid heating die can significantly save processing energy consumption and achieve better surface quality.
4. Ensure the balanced filling of each cavity, help to shorten the molding cycle, ensure the stability of product quality, and have excellent energy-saving effect.
5. The use of CAE aided design technology for mold design, mold flow analysis and simulation can reduce the energy consumption of mold debugging and multiple mold repairs.
6. On the premise of ensuring product quality, the use of lower clamping force for molding will help to prolong the life of the mold, facilitate the rapid filling of the mold, and help to save energy.
7. Do a good job in mold maintenance to ensure effective heating and cooling water channel conditions.
