The energy recovery system in the molding machine usually refers to the utilization of waste heat or energy generated during the production process to convert it into reusable energy, in order to reduce energy consumption and environmental impact. Although some advanced molding machines may be equipped with energy recovery systems, not all molding machines have such functionality.
The energy recovery system may take the following forms in the molding machine:
Cooling water recovery system: During the injection molding process, a large amount of cooling water is usually required to lower the mold temperature and cool the formed parts. After passing through the mold, cooling water may take away a certain amount of heat. By installing a recovery device, this heat can be converted into reusable energy, such as for heating water or providing domestic hot water.
Waste heat recovery system: During the operation of the molding machine, a large amount of waste heat may be generated, such as the heat generated during the operation of the motor or the heat generated during the operation of the hydraulic system. By installing waste heat recovery devices, this waste heat can be captured and converted into usable energy, such as for heating production workshops or other facilities.
Mechanical energy recovery system: In some molding machines, such as high-performance servo drive systems, there may be a mechanical energy recovery system that can convert the inertial energy generated during braking into electrical energy, which is then fed back to the power grid to reduce energy consumption.
The implementation of energy recovery systems can help reduce the energy consumption and production costs of molding machines, while reducing their impact on the environment. However, its implementation requires customized design and installation based on specific circumstances, which may increase the cost and complexity of the equipment.
