| Mechanism | Description |
|---|---|
| Mold clamping | Mold clamped |
| Nozzle touch | Nozzle pushed into mold |
| Injection | Resin injected |
| Measuring | Resin fill level measured |
| Ejection | Molded item ejected from mold |
| Safety | Mold clamping stopped when safety door opens |
| Back pressure control | Screw prevented from thrusting back due to resin pressure |
Pump control systems are used to achieve energy efficiency. They control the pump's variable capacity mechanism with electric signals to govern both pressure and flow.
In recent years, attention has turned to systems that deploy AC servo motors to drive the pump and to control rotation frequency. Controlling the pump's rotation frequency makes it possible to supply power to rotate the motor only when needed, improving energy efficiency.
- Energy savings
- Outstanding repeatability / reproducibility
- Energy savings
- Low noise
- High performance
Valve control is often used for applications requiring high-speed injection. Pressure and flow are controlled by a fixed volume pump and highly responsive proportional valve or servo valve.
- Straightforward usability
- High precision and high response
- Outstanding contamination
