Injection Unit

 

Modular injection unit combination

  • Custom configurations can be achieved through modular injection unit combinations tailored to specific process requirements, supported by adaptable and scalable software functionalities.
  • Specially engineered screw designs are available for processing PET, PC, PMMA, PVC, PA, PPS, and other engineering thermoplastics.
  • The dual-cylinder balancing injection mechanism enhances the reliability and pressure capacity of the injection unit.
  • Featuring self-adaptive temperature control technology, the system achieves static temperature accuracy of up to ±0.4 °C.

Control System

 

  • A high-performance and fast-response industrial controller designed for multi-component injection molding machines enables precise and synchronized control of multiple injection units. Through real-time synchronous communication, production data is seamlessly exchanged with the rotary table system, ensuring accurate positioning and stable coordinated operation.
  • Remote online production monitoring
  • Statistical process control for multiple injection units
  • Configuration and tracking of critical motion curves
  • Early deceleration and precise positioning control
  • Built-in hot runner control expansion capability
  • Integrated control of auxiliary equipment systems

Servo Motor System

 

  • Equipped with a high-precision pressure sensor, rotary encoder, and pressure transducer, the system enables independent monitoring and control of flow and pressure parameters. Based on real-time feedback, the high-performance synchronous servo motor automatically adjusts output flow and pressure by regulating speed and torque. This closed-loop control system ensures stable operation and consistent product quality.
  • During the cooling phase, the motor remains inactive, resulting in zero power consumption. Compared with conventional injection molding machines, energy savings of 30%–80% can be achieved.
