7, do a good job of mold maintenance to ensure effective heating and cooling waterway conditions.

Peripheral equipment
1, Choose auxiliary equipment suitable for the capacity to meet the work requirements, but not too much affluence.
2, Do a good job of equipment maintenance to ensure that the equipment is in normal working condition. Auxiliary equipment that does not work properly will cause production instability or even poor quality parts, resulting in increased energy consumption.
3, Optimize the host and peripheral equipment to work with the work and the order of operation.
4, optimize the peripheral equipment and production equipment mutual position, without affecting the operating conditions, as far as possible, so that the peripheral equipment from the host closer.
5, many auxiliary equipment manufacturers provide on-demand energy supply system, which can achieve significant energy savings.
6, the use of rapid mold change equipment to reduce the waiting time required to switch products in production.

Materials
Different materials processing energy consumption is different, while poor management of materials or improper management of recycled materials will cause an increase in production energy consumption.
1, under the premise of meeting the performance of the products, should give priority to the selection of materials with lower processing energy consumption.
2, in order to meet the use of performance and cost optimization conditions, priority should be given to the selection of high liquidity materials.
3, note that different suppliers of materials may have different process conditions.
4, material drying treatment, the best with the drying with the use, to avoid drying the material moisture waste of energy.
5, do a good job of material preservation, to prevent the material mixed with impurities or foreign objects, ultimately resulting in poor products.
6, part of the products allowed to join a certain amount of recycled materials, but should pay attention to the preservation of recycled materials and cleanliness, to avoid unclean materials produced by poor parts.

Processing technology
1, Use the shortest molding cycle under the premise of meeting the performance of the products.
2, If there are no special factors, use the processing technology recommended by the supplier for processing as far as possible.
3, for specific products and molds, all stable equipment and process parameters to save, shorten the next replacement of the production of machine adjustment time.
4, Optimize the process, using lower clamping force, shorter cooling time and holding time.

Adopt new technology
1, Adopt auxiliary molding technology, such as gas-assisted, liquid-assisted, steam-assisted, micro-foam injection molding technology.
2, Adopt unitized molding scheme to reduce intermediate links.
3, Adopt new technologies such as in-mold welding, in-mold spraying, in-mold assembly and in-mold decoration.
4, Adopt new low-pressure molding technology to shorten the molding cycle, and at the same time can reduce the melt temperature.
5, Adopt energy regeneration system.

Production management
1, Produce high-quality products at one time, reduce the defective rate is the biggest energy-saving.
2, The maintenance of the whole production system is closely related to energy consumption. This not only involves the host, but also the periphery and factory equipment, for example, if the workshop mold crane failure, the need for manpower to change the mold, is bound to extend the waiting time of the equipment, resulting in an increase in energy consumption of the equipment.
3, Equipped with workshop energy consumption monitoring system to facilitate the implementation of energy analysis and improvement of the enterprise purpose.
4, equipment downtime maintenance, not only to check the maintenance of the equipment itself and the project, but also to pay attention to the equipment and other systems connected to the condition of the work performance is reliable.
5, Regularly compare with industry benchmarks to see if there is room for further improvement.
6, And suppliers to establish a reliable contract and cooperative relations, energy-saving management of enterprises is beneficial.
