Most heating problems on plastics lines don’t come from lack of power, they come from how that power is controlled.

At Interplas 2026, CD Automation are focusing on the part that usually gets overlooked. If you’re running single or three-phase heaters, whether that’s across a multi-zone extrusion barrel or a hot runner system, you’re already dealing with uneven loading, thermal lag, and zones that don’t behave the same way twice.

It looks fine on paper. In practice, that’s where instability creeps in. One zone hunts, another overshoots, and before long you’re compensating in the process rather than fixing the cause.

CD Automation build thyristor (SCR) power controllers and systems to deal with that properly, stable power delivery, predictable response, and control that matches how the heat actually behaves, not how it was assumed to behave.

If you’re involved in plastics machine design or responsible for keeping a process running consistently, it’s worth stopping by for a proper conversation, not a sales pitch, just a look at what’s actually happening on your system.
