Modular Hot Runner Temperature Controllers
Rack-Based Modular Controllers
- Central rack + plug-in modules
- Each module controls one zone
- Scalable (add more zones as needed)
Plug-in Card Controllers
- Individual cards inserted into rack
- Each card = one heating zone
- Easy to replace (when something inevitably fails)
Portable / Compact Controllers
- Standalone units
- Limited zones
Multi-Zone Controllers
- Controls multiple heating zones simultaneously
- Ensures uniform temperature across mold
PID Temperature Controllers
- Uses PID control
- Maintains stable and accurate temperature
- Minimizes overshoot and fluctuations
Touchscreen / Smart Controllers
- Digital interface
- Advanced monitoring & alarms
- Data logging, diagnostics

Key Features (What separates good from “why is this unstable?”)
- Closed-loop control (PID)
- Auto-tuning
- Zone-wise temperature control
- Alarm systems (over/under temp)
- Soft start (heater protection)
- Communication (PLC integration)
- PID Control → precise, stable
- ON/OFF Control → cheap, unstable
- Phase Angle / Zero Cross Control → power regulation methods
