Xaloy Inc. said its new nXheat, noncontact, induction-barrel heating method uses electromagnetic induction, which uses much less energy than traditional heater bands for injection molding.
The barrel is cool to the touch.
The nXheat uses a high-frequency power supply and helical induction coils to generate heat directly within the barrel wall — without coming into contact with the barrel. According to the company, the new heating system has energy savings of up to 70 percent, from heater bands, with a 95 percent efficiency. An additional 35 percent of energy savings come from reduced demand for air conditioning, since the outside of the barrel does not get hot, as well as from reduced peak-power demand.
The nXheat heats up and cools down immediately. It also has more heating capacity, normally about three times higher wattage into the barrel, according to Xaloy.
A stand-alone induction power module runs the nXheat barrel heater.
Xaloy, of New Castle, Pa., also highlighted a new development in downstream extrusion. Pneumatic air now powers the slide plate on Xaloy's XP air-assisted manual screen changer. The XP uses the plant's air supply, using no hydraulics or electrical controls. The unit fits extruders of any size, between 60 and 120 millimeters.
