These machines utilize servo motors for all movements and functions, including plasticizing, injection, clamping, and ejection. This differs from hydraulic or hybrid machines, which rely on hydraulic systems for some or all of these processes. A typical example would be a machine used to produce precision plastic parts for electronics or medical devices, relying solely on electrical power for operation.
The benefits of this technology include enhanced energy efficiency due to the elimination of hydraulic systems and their associated energy losses. Precision and control are also significantly improved, leading to higher quality products with tighter tolerances and less waste. Additionally, the reduced noise and emissions contribute to a more environmentally friendly manufacturing process. Historically, the development of powerful and responsive servo motors has enabled the viability and increasing popularity of this fully electric approach, paving the way for more sustainable and precise plastic part production.
