For an injection molding factory, the energy consumption of the injection molding process accounts for about 60%, so effectively reducing the energy consumption of the injection molding machine is an important way to save energy. With the continuous improvement of energy-saving technology of injection molding machine itself, reducing the overall energy consumption of injection molding plant needs to be considered from the aspects of production management, processing technology and materials, production workshop supporting, etc.

一、生产车间

1、 Production workshop

生产车间布局着重从两方面考虑：满足生产需求条件下，根据生产流程进行优化布局的同时，满足特定生产条件下灵活用能的要求。

The layout of production workshop is mainly considered from two aspects: under the condition of meeting the production demand, optimize the layout according to the production process, and meet the requirements of flexible energy use under specific production conditions.

二、注塑成型机

2、 Injection molding machine

注塑机是注塑车间能源消耗大户，耗能主要为电机与加热两部分。

Injection molding machine is a major energy consumer in injection molding workshop, which mainly includes motor and heating.

1、根据制品特点选择合适的注塑机。“大马拉小车”式的注塑加工往往意味着大量的能源浪费。

1. Choose the right injection molding machine according to the product characteristics“ The "big horse pull small car" injection molding process often means a lot of energy waste.

2、选用全电动注塑机与混合动力注塑机，具有优异的节能效果，可节能20-80%。

2. All electric injection molding machine and hybrid injection molding machine have excellent energy saving effect, which can save 20-80% energy.

3、采用新型加热技术，如电磁感应加热、红外加热等，可实现20-70%的加热节能。

3. Using new heating technology, such as electromagnetic induction heating, infrared heating, can achieve 20-70% heating energy saving.

4、为加热、冷却系统采用有用的保温绝缘措施，减少热、冷损失。

4. In order to reduce the heat and cold loss, the useful insulation measures are adopted for the heating and cooling system.

5、保持设备传动部件良好的润滑，减少由于摩擦加大或设备运行不稳定引起的能耗增加。

5. Keep the transmission parts of the equipment well lubricated, reduce the increase of energy consumption caused by increased friction or unstable operation of the equipment.

三、注塑模具

3、 Injection mold

模具结构与模具状况往往对注塑成型周期及加工能耗有显著影响。

Mold structure and mold condition often have a significant impact on injection molding cycle and processing energy consumption.

1、合理的模具设计，包括流道设计、浇口形式、型腔数、加热冷却水道等，均有助于降低能耗。

1. Reasonable mold design, including runner design, gate form, cavity number, heating and cooling channels, can help to reduce energy consumption.

2、采用热流道模具，不仅可以节约材料，减少物料回收能耗，其成型过程本身也具有显著的节能效果。

2. Using hot runner mold can not only save materials and reduce the energy consumption of material recovery, but also has significant energy-saving effect in the forming process itself.

3、仿形快冷快热模具可以显著节约加工能耗，并实现更佳表面质量。

3. Profiling rapid cooling and rapid heating mold can significantly save energy consumption and achieve better surface quality.

4、确保各腔均衡充填，有助于缩短成型周期，保证制品质量均一性，有优异的节能效果。

4. To ensure the balanced filling of each cavity is helpful to shorten the molding cycle, ensure the uniformity of product quality, and have excellent energy-saving effect.

5、采用CAE辅助设计技术进行模具设计、模流分析与模拟，可以减少模具调试与多次修模的耗能。

5. Using CAE aided design technology for mold design, mold flow analysis and simulation can reduce the energy consumption of mold debugging and multiple repair.

6、在保证产品质量的前提下，使用较低锁模力成型，有助延长模具寿命，利于模具快速充满，有助节能。

6. On the premise of ensuring the quality of products, the use of low clamping force for forming helps to extend the service life of the mold, is conducive to the rapid filling of the mold, and is conducive to energy saving.

7、做好模具维护工作，确保有用的加热冷却水道状况。

7. Do a good job in mold maintenance to ensure the condition of useful heating and cooling channels.
