Hot Runner Controller
A Hot Runner Controller is a specialized temperature control unit used in plastic injection molding systems to regulate the temperature of the hot runner manifold and nozzles. It ensures precise, consistent temperature across all zones of the hot runner system, which is critical for optimal flow, balanced filling, and high-quality molded parts. It prevents issues like flow imbalance, gate freezing, or material degradation.
Key Features
- Multi-zone Temperature Control: Available in 1 to 48 zones or more
- High-Precision PID Control: Stable and responsive heat regulation
- Modular Design: Plug-in cards/modules for each zone
- Auto/Manual Mode: Easy switching with real-time status display
- Graphical Interface: Touchscreen HMI or digital display for temperature monitoring
- Sensor Break Detection: Alerts in case of thermocouple failure
- Heater Burnout Protection: Increases system safety and reliability
- Soft Start Function: Gradual heating to prevent thermal shock
- Data Logging: Optional USB or Ethernet port for temperature history tracking
- Compact and portable: Rack or tabletop models available
