Stability through precise temperature control

TempMaster temperature controllers

TempMaster temperature controllers deliver stability, quality and maximum control over the injection molding process.

TempMaster

Controller technology

See how APS, Soft Start and plastic leak detection support stable temperature control and protect the hot runner system.

TempMaster

Auto-Tuning APS (Adaptive Process System) algorithm

TempMaster’s APS algorithm continuously monitors, predicts and adapts to the process variables of each zone individually for precise temperature control.

The APS algorithm monitors, learns and adjusts to process changes in each temperature zone. The diagram shows the temperature remaining close to the setpoint compared with control without APS.

APS keeps temperature closer to the setpoint in the comparison shown.

Diagnostics

Complete diagnostics of the hot runner system.

All Mold-Masters TempMaster temperature controllers (except the MT series) come with a diagnostics function as standard. It is essential for hot runner maintenance and is run before the mold goes into production, as it provides useful reports on the condition of the system:

  • Electrical resistance of heaters in nozzles, manifolds and other electrically heated components
  • Deviation from the previous measurement
  • Thermocouple and heater wiring information

Soft Start

A low voltage start protects damp heaters from electrical arc damage.

Mold-Masters TempMaster temperature controllers (except the MT series) come with the Soft Start safety function as standard. The insulating material inside the heaters can absorb moisture from the environment, and applying full power directly can cause a short circuit in the heater. Soft Start ramps up from a reduced voltage and dries the moisture out gradually, minimising the risk of a short circuit and extending heater life.

Moisture from the insulating material can cause arcing and burn out the heater when high voltage is applied.

Soft Start begins heating at very low voltage and ramps it up gradually, while conventional controllers apply high voltage from the very start.

Plastic leak detection

Detects and prevents plastic leaks in the mold.

Advanced Mold-Masters TempMaster temperature controllers feature plastic leak detection (APS). The controller detects leaks and alerts the operator at an early stage and, if the controller is connected to the injection molding machine, it can be set to stop the injection process. This function prevents costly damage, such as the hot runner being completely flooded with plastic.

No plastic leak around the hot runner nozzle
No leaks, normal power %
Small plastic leak beginning around the nozzle
Leak starts, % increases
Plastic leak spreading around the nozzle
Heat is lost to the cooled cavity plate
Heater power rising above the power alarm limit and triggering STOP mode
When the power limit set automatically by the controller is reached, the alarm is triggered and the controller switches to STOP mode.
