G 25 Hot Runner
Temperature Controller
Accurate temperature management is essential for manufacturing high-quality parts with minimal waste, ensuring both operational efficiency and profitability. Gammaflux's high-precision, user-friendly control technology enables advanced temperature regulation for your hot runner systems.
Building on the success of the globally favored G 24, the newly launched G 25 offers a completely redesigned user interface along with enhanced features, setting a new standard in precision temperature control.


Why the G 25 delivers smooth, precise power to each heater:
Triangulated Control Technology®
The task of the hot runner controller is to measure the temperature at various points on the mold (such as the nozzle and the manifold), compare it with the material-specific target value, and correct it if necessary. To do this, the G25 uses its sensors to measure 20 times per second and readjusts the temperature with a precision of 0.017 degrees Celsius.
While simple systems attempt to make these corrections in proportion to time (heating on/off in defined periods), Gammaflux manufactures so-called PIDD controllers, in which algorithms modulate the control variable using three components: proportional, integral, and differential.
In doing so, both the immediate deviation as well as a deviation accumulated over time and an anticipated deviation are taken into account. As with dimmers for lighting systems, Gammaflux uses phase angle control, which cuts the current flow of the alternating voltage so that it is no longer sinusoidal. A major advantage over resistance-based circuits is the low power loss.
This advanced technology helps achieve:
- Better temperature consistency
- Improved part quality
- Reduced waste
- Consistent part weight
- Material savings
- Increased profit margins
What You Can Expect
Easy Set Up with Mold Wizard®
The G25 is built for simplicity. It is designed to operate seamlessly based on industry best practices. The New Mold Wizard® effortlessly assists users through each stage: starting from configuring zones and settings to advanced tasks such as mold startup and heating.
- Configure Mold and Layout
- Run Automatic Hot Runner Detection
The Industry's First Database- Based Configuration
As operators initiate the set-up process, they'll find a valuable addition in the G 25: set values can be directly sourced from an integrated material database containing manufacturer information. This feature enhances safety and simplifies the setup.
A special feature that no other controller offers!
- Select Material from Industry-Leading Materials Database
Easy Troubleshoot with Mold Doctor®
Troubleshooting is made easy. This feature analyzes thermodynamic data to help pinpoint sudden, elusive problems in the mold, providing a quick and accurate diagnosis.
- Fault Analysis
- Wiring Analysis
- Thermodynamic Analysis
- Historical Performance Analysis
- Auto Tuning
- Early Leak Detection
Full Traceability by Historical Mold Performance
The performance of the hot runner can also be recorded, documented and referenced over longer periods of time:
Do the nozzles still respond as they did at the beginning?
Has the power consumption remained the same?
The G25 provides answers to questions like these. All production information is stored in an integrated database. Even if the controller is used on a different injection molding machine, the data is retained and ensures complete traceability.
- Live Visualisation
- Historical Performance

Full Integration with Web Interface
- Hosting on all browsers with the latest web technology
- All OPC-UA interfaces comply with the Euromap 82.2 standard
- Integration into the machine's control system possible
- Evaluation through an MES system, as well as easy data reading and storage on a central computer
