Hot Runner Temperature Controllers -- 24 Zone and Above

Hot Runner Controllers
Hot runner controllers are specialized temperature controllers that keep specialized injection-mold components at the design temperature in order to keep the plastic flowing. They use several different control techniques. Limit control establishes set points that, when reached, sends a signal from the hot runner control to stop or start a process variable. Linear control matches a variable input signal with a correspondingly variable control signal. Feedforward control does not require a temperature sensor and provides direct control-compensation from the reference signal. Proportional, integral and derivative (PID) control requires real-time system feedback. PID control also monitors the error between the desired variable value and the actual value. Fuzzy logic is a hot runner temperature control technique in which variables can have imprecise values (as in partial truth) rather than a binary status (completely true or completely false). Hot runner controllers that use advanced or non-linear controls such as neural networking, adaptive gain, or emerging algorithms are also available.

The Pulse® Series integrated hot runner temperature controller, available in capacities to 180 zones, provides a wide range of injection molding processors with a new level of reliability- and productivity-enhancing features. For example, with a simple-to-use display incorporating universal symbols, standard Pulse operations can be learned in a fraction of the time required by conventional systems. Pulse utilizes advanced, Fast Tune 2 (FT2) for automatic tuning plus waterfall technology to optimize peak energy usage. Additionally, Pulse incorporates ATP™(Active Thermocouple Protection) circuitry and is compatible with new, Fast Heat Mold IQ™ technology enabling Pulse to retrieve data such as file recipes, mold set-ups, history and more from a microprocessor embedded in the mold box. All these, and many other features are now included in a significantly reduced footprint.
