Can design of experiments optimize energy consumption in plastic injection molding?

Several studies have utilized Design of Experiments (DOE) to optimize energy consumption in plastic injection molding, supporting our methodology. Kitayama et al. (2017), used the Taguchi method to optimize injection speed, mold temperature, and holding pressure, focusing on energy efficiency and cycle time.

How much energy does injection molding use?

However, over 90% of the energy costs in injection molding are accounted for by electricity [ 3, 4 ], so energy consumption remains high. It is estimated that these injection-molding plants in the United States consume around 30 billion kWh of electricity annually [ 5, 6 ].

What is injection molding process?

The injection molding (IM) process is a widely used manufacturing process for injecting material into a mold for producing a diverse array of parts. It includes several energy-consuming procedures, such as heating plastic pellets, forcing melted polymer into a mold cavity, and cooling down the molded products.

How does plastic injection molding contribute to cleaner production and sustainability?

As such, this study has multiple connections to cleaner production and sustainability. It primarily concentrates on optimizing the plastic injection molding process to minimize energy consumption, which directly contributes to cleaner production by minimizing the environmental footprint of manufacturing.

Should plastic injection molding process be optimized?

The findings you referenced about optimizing the plastic injection molding process are well-supported in the literature. Studies have shown that process optimization can significantly reduce specific energy consumption and cycle time, resulting in cost savings and enhanced sustainability.

How do mold design parameters affect energy consumption?

Mold design parameters, such as the gating system, sprue geometry, and runner layout, are important to the entire energy usage (ETSU&BPF 1999). A hot runner design could lower the overall energy consumption compared to a cold runner design (Rosato et al. 2000).
