Servo Injection Molding Machines – HRS & HRFC Series
ー Engineered for Efficiency, Speed, and Unmatched Precision
Our servo injection technology strikes the ideal balance of speed, energy efficiency, and precision. Designed to meet the evolving needs of modern manufacturing, our system reduces power consumption, shortens cycle times, and maintains consistent part quality.
Servo Machine Features

High-Response Servo System
Precision encoder and proportional valve enable real-time closed-loop control of injection speed and pressure. Improves response time by over 40% vs. traditional systems, enhancing repeatability and shot consistency.
Energy Efficiency up to 70%
Patented servo power-saving system (Patent M327493, M328970) reduces energy consumption and lowers operating costs.

Low-Noise Operation
Servo-driven control reduces mechanical noise during movement, enabling quieter production and a more operator-friendly workspace.
Optimized Hydraulic Circuit
Built-in sensors and smart PID tuning reduce oil temperature and boost actuator responsiveness — ideal for precision molding in optical and medical applications.
