STX Series
X-Pump

Flexible, Compact, and Energy-Efficient Vertical Machine!

Evolving from the ST Series, the STX Series is equipped with the hybrid X-Pump® System, inheriting its compact design and automation flexibility from the predecessor. It offers outstanding injection performance and energy-efficiency, possessing excellent capability for the molding of high-precision automotive and electronics parts.

Intelligent Hybrid
X-Pump® System

"Fusion of Hydraulic Control and Servomotor Drive Technologies"
The X-Pump System combines years of accumulated expertise in hydraulic and state-of-the-art servomotor drive technologies. Since the servomotor rotates at the required speed only when necessary, the extremely efficient X-Pump achieves drastic energy-savings. Furthermore, with exceptional stability in injection repeatability and controllability in low velocity/pressure range, it makes production of higher-precision and higher-quality molded products possible.
