It’s no wonder all-electric plastic injection molding equipment is growing in popularity. Why? Unlike traditional hydraulic injection molding machines, which use energy even when not producing anything, all-electric injection molding machines consume energy only when required for a specified product, and motor output is matched to load requirements.
Instead of being driven by liquid, all-electric machines use digitally controlled, high speed and highly efficient servo motors to power the whole process. Each axis is controlled by an independent motor for the four basic processes of plastic injection molding: injection, extruder, clamping and ejection.
The result is a faster, cleaner, more repeatable and energy efficient injection molding process. Energy consumption for an all-electric machine can be reduced by 50 to 75% over that for a hydraulic machine. Currently, all-electric injection molding machines now make up over half the injection molding machines sold annually in the United States. Shocking? Hardly!
