G Series of injection molding machine to take the high speed and low pressure injection and multi action composite operation design concept, but also utilized optimized clamping unit and lubrication unit and regenerated hyraulic system, thereby it guarantees a shortened circle time for thin wall products. Comparing with normal type machine, high speed servo series machine priors to both circle time and energy-saving, minizing the overload of mechnical structure and hydraulic motor, heightening stability and lifespan.
