MCS® Hot runner controller – precise and convenient process control


The new generation of MCS hot runner controllers offers reliable and precise control of the hot runner system with the simplest possible operation. The fast control behavior makes the hot runner controllers universally applicable for the control of all standard systems, but also for demanding high performance applications with slim nozzles of low mass. Integrated interfaces for optimum communication with the injection molding machine and extensive support and error detection functions complete the equipment.


The main focus of the new development was the intuitive user interface, which allows the controller to be operated without instruction or prior knowledge. With unique and innovative functions, even untrained users can operate the controller safely.

The Highlights

Self-explanatory user interface

A self-explanatory operating structure with expressive icons and clearly visible touch fields greatly simplify operation.

Individual zone display

The operator can choose from numerous process values those which should be displayed in the zone display. This allows the zone display to be set individually for each applica-tion.

Operating instructions in plain text

With each input, the operator is instructed in clear text, which action has to be performed. Therefore it’s possible to operate the controller without any prior knowledge and make the appropriate settings.

Quick start

The quick start leads through the essential settings (groups, operating mode and set points) in order to put the controller into operation as soon as possible when changing molds. This will ensure that the most important settings are made.

Integrated help function for all settings

A short description of each function and setting can be called up by touching the i-icon. This avoids an annoying search in the manual.

Keyword index with quick links

All settings and functions of the controller can be selected via the index. With a touch on the searched term it’s possible to navigate directly to the view, in which the appropriate input is made.

Illustrated step-by-step instructions for trouble shooting

With the step-by-step instructions, the user can correct errors himself, which minimizes downtimes. Multiple faults in a zone are listed individually in the diagnostics and can be analyzed individually using the troubleshooting guide.

Seamless recording of all events

All status changes of the controller, e. g. malfunctions or changes of settings are recorded chronologically in an event list. With this complete documentation, processes can be optimized and errors traced. The event list can also be saved and can be read out via USB stick.

Service-friendly construction

Electronic components such as triacs or power cards are easily accessible and can be replaced without opening the device.

Chart recorder

The chart recorder is used for the analysis the control behavior of zones by displaying the time course of the process values  – actual value, setpoint and output level – in a curve diagram.

Many more features


Several zones can be combined into groups and parameterised as one. This facilitates commissioning.

Control Inputs out outputs

Digital control inputs are used to select injection moulding recipes or activate control commands such as Release and Standby. The alarm contacts enable centralised monitoring.

Sequential heating and cooling

Zones can be grouped and sequentially heated up, creating a clean seal on the nozzle tip. Controlled cooling is also possible.

Tool storage

The tool storage stores the configuration data for all of the zones. This saves time and prevents input errors when the machine is restarted after a tool change.

Group heating

Cold zones are slowly heated without impacting the slower zones. This preserves the nozzles and material and prevents a thermal imbalance from occurring in the hot runner system.

Available Diagnostics

All of the zones can be diagnosed to make sure they’re working properly. The detection of inverted or reversed wiring, for example, increases operational safety.

Controlled continued heating in case of a sensor failure

The Auto-Power function enables controlled continued heating in the event of a sensor failure thereby reducing production downtime.

Service file

The service file can be generated by the user if required. It contains technical data as well as recordings of the cam recorder, which provide valuable information for error analysis in the event of a fault.

Gentle heating

The Softstart function gently heats up the elements by limiting the power based on the temperature.
