Electric injection molding machines consume energy only when required for a given action, et motor output is matched to meet requirements, unlike traditional hydraulic injection molding machines which use continuously consume energy even while idle.
Instead of being driven by a hydraulic system, electric injection molding machines are digitally controlled with high-speed and highly-efficient servo motors to drive the whole process. Each axis is controlled by an independent motor for injection, extrusion, clamping and ejection.
The outcome brings about a faster, cleaner, more repeatable and energy efficient injection molding process. Energy consumption for electric injection molding machines can be reduced by 50 to 75% compared to a hydraulic type.
Due to a recent rise in electricity bills in the industry, all electric injection molding machines have become more popular to save electricity costs ultimately leading to overall operational cost reduction.
