这种注塑成型的环境分析突出了几个要点。注塑机类型（液压、混合动力或全电动）的选择对比能耗（SEC）有很大影响。分析的液压、混合动力和全电动机器的SEC值分别为19.0、13.2和12.6 MJ/kg（包括辅助设备、复合和电网的低效率）。对于液压和混合动力机器，SEC似乎表现出随着吞吐量增加而降低的行为。这是因为随着产量的增加，固定的能源成本会分摊到更多公斤的聚合物上。对于全电动机器，SEC随吞吐量而恒定。当聚合物生产阶段包括在分析中时，能量消耗值增加到100 MJ/kg。美国每年的整体注塑能耗为108 GJ的2.06倍。这一数值与美国砂型铸造的总能耗以及一些发达国家的总发电量相当
This environmental analysis of injection molding highlights a few important points. The choice of injection molding machine type (hydraulic, hybrid or all-electric) has a substantial impact on the specific energy consumption (SEC). The SEC values for hydraulic, hybrid and all-electric machines analyzed are 19.0, 13.2 and 12.6 MJ/kg respectively (including auxiliaries, compounding and the inefficiency of the electric grid). For hydraulic and hybrid machines SEC seems to exhibit a decreasing behavior with increasing throughput. This derives from spreading fixed energy costs over more kilograms of polymer as throughput increases. For all-electric machines SEC is constant with throughput. When the polymer production stage is included in the analysis, the energy consumption values increase up to 100 MJ/kg. The overall injection molding energy consumption in the U.S. in a yearly basis amounts to 2.06 times 108 GJ. This value is of similar magnitude to the overall U.S. energy consumption for sand casting, and to the entire electricity production of some developed countries
