6 FAQs about [Energy storage for press mold opening]

How does holding pressure affect a mold?

Holding pressure prevents defects by compensating for shrinkage, and mold closing movement affects cycle time through closure precision. Injection pressure influences mold fill and part quality, while mold opening speed reduces cycle time by enabling quicker part ejection.

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 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).

How does injection pressure affect mold opening speed?

Injection pressure (bar) forces molten plastic into the mold, with higher pressures for complex molds or thin sections (Osswald and Hernandez-Ortiz, 2006). Mold opening speed controls how fast the mold halves separate post-cooling, influencing cycle time (Brent, 2005).

What are the specifications of a mold machine?

Further details include the machine's specifications: clamping force of 4052 kN, injection stroke of 64 mm, holding pressure of 770 bar, and mold closing movement of 70/60/45/30 bar.
