Energy storage power injection molding factory

What is the ideal manufacturing energy in the injection molding process?

The ideal manufacturing energy in the injection molding process for a part is mentioned in Eq. (1), which is a sum of the energy required for the sub-processes of the injection molding process. The energy required by these sub-processes is found using Eqs. (A3), (A4), (A5), (A6), (A7), (A8), given in the Appendix.

How to calculate energy consumption for injection molding part manufacturing?

The energy consumption for an injection molding part manufacturing can therefore be computed using equations 23-26. If we take into account the injection molding process only, the energy used for a single shot is sum of the energy required for all the drives, as given in Eq. 23. E = + + + .

Does injection molding use a lot of energy?

Further, the extent of energy use in the injection molding process is well recognized (Gutowski et al., 2006 ), and it consists of a number of identifiable and controllable steps, required for energy performance evaluation and improvement.

Is injection molding a KPI for sustainable manufacturing?

Energy is an important KPI for sustainable manufacturing and is the focus in this paper. In this paper, we selected the injection molding process for characterizing energy. Injection molded parts are widely used in consumer products and industrial equipment.

Why do injection molding machines impose a high demand on Drive and control systems?

These energy losses are added to the theoretical minimum energy requirements of the various operations of the injection molding process. Injection molding machines impose a very high demand on the drive and control systems, because of the fact that the plastic injection molding process is complex and the machine cycle times are mostly short .

What is process inefficiency in injection molding?

With reference to the injection molding, process inefficiency could refer to the energy required due to the presence of the gating system, which does not directly contribute to the process but is an essential process requirement. By reducing the size of the gating system or such other inefficiencies, the performance rating may be improved.
