Key Components
Clamp design

Features a rigid mold plate that reduces elastic deformation and lowers the required clamping force. It includes high-speed proportional valves for faster response, more accurate positioning, and reduced cycle times.

Servo motor

Equipped with a high-performance servo system that quickly responds to up to 40 m/s and reduces energy usage by 30%-70%. Its modular design makes maintenance easy.

Innovative frame construction

The structure uses non-welded pipelines, decreasing the risk of oil leaks and enhancing the plastic processing machine's durability and cleanliness.

Precision injection

The dual linear rails support the injection unit, minimizing friction and improving accuracy. The hydraulic injection molding machine uses a medium-inertia, single-cylinder injection mechanism for quick and consistent operation.

Features
  • Includes a KEBA control system for efficient management.
  • Features a fast action scanning period of less than 1 ms.
  • Ergonomically designed for comfortable use.
  • Uses infrared nano-heating rings that heat up quickly and maintain temperature effectively, achieving over 30% energy savings.
  • Employs PID temperature control to maintain tight temperature accuracy within ±1°C.
  • The high L/D ratio screw enhances mixing and plasticizing efficiency.
  • Models SA-650p and above are equipped with automatic feeding, enabling shorter molding cycles through dual-circuit actions.
