How Does A Hot Runner Controller Work
What Is A Hot Runner Temperature Controller?
A hot runner controller is a specialized temperature controller that keeps specialized injection-mold components at the design temperature in order to keep the mold material flowing. This helps create the most consistent part(s). As one of the essential accessories of the hot runner system, it is interdependent with the hot runner system, but relatively independent. Its accuracy and stability seriously affect the hot runner system, while hot runner system also has an impact on hot runner controller’s accuracy, stability, service life, etc.
Here are some kinds of hot runner controllers widely used in the market, HMI based hot runner controllers, standard plug-in hot runner controllers, one card control two zones and 48*48 PID control unit. And many brands you can see, for instance, Synventive, HUSKY, MASTIP, Gammaflux, EWIKEN, DME, POLIMOLD, MCS and many other brands.
A hot runner controller consists of control module, mainframe, connectors and cables.
How does a hot runner controller work?
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.
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.
