Jay Kay Heaters is a trusted Induction Band Heater Manufacturer in Noida, India, offering advanced induction heating solutions for plastic processing, extrusion, injection moulding, blow moulding, and other industrial applications. Our induction band heaters are designed to provide rapid and uniform heating while significantly reducing energy consumption compared to conventional heating methods. With precise temperature control and high thermal efficiency, they help improve production performance, reduce operating costs, and ensure consistent process quality.
The barrel heating system uses electromagnetic induction – a well-known principle used to heat large industrial furnaces, special machines for injection molding molten metal, thermoset molds and some Japanese hot-runner nozzles. However, it is a new concept for heating barrels of extruders. The system, introduced by Jay-Kay, turns the steel barrel itself into a resistance heater by generating electrical eddy currents in the metal near the outer surface of the barrel tube. Those eddy currents are induced by electrical current passing through a cable wrapped in a continuous coil around the barrel but not touching it.
Although the initial cost is more than heater bands, an induction heating system pays for itself in several ways, depending on machine size.
Our measurements indicate that the heating efficiency of a ceramic band heater may be 10–15% higher. The remaining energy is wasted by radiation and convection to the surrounding environment. In contrast, induction heating radiation losses are minimized by the insulating sleeves, which rise to a temperature of around 60–70°C during operation.
