World’s smallest heating cartridge finds niche application in hot runner nozzles

Maker of compact electric heating elements Türk+Hillinger (Tubingen, Germany) will showcase what it claims is the world’s smallest heating cartridge for standard voltages at K 2019 in Düsseldorf, Germany. This component and the company’s other small, high-performance cartridge heaters are designed to meet demanding applications in the medical, automotive, laboratory and semiconductor industries. They are also used in hot runner plastic injection nozzles and have applications in packaging machines and cosmetic and consumer products, as they can heat complex systems to very precise temperatures.

The company’s Type HLP heaters are well established in the marketplace and feature a design with a high surface load that delivers high performance in space-constrained applications. The compact heating elements are available in lengths from 10 to 150 mm with a maximum surface load up to 70 W/cm² and a maximum sheath temperature of up to 750°C. The miniature cartridge heaters are made with insulated PTFE strands and are available for both low- and standard-voltage applications up to 250 V. 

The heating elements are manufactured according to customer specifications.

The development of a 2-mm-diameter heating element achieved a new threshold, according to the company. “The development was challenging and our testing was extensive, so we are proud to offer these micro heaters to our demanding customers,” said Andreas Schlipf, Technical Director and Chief Technologuy Officer.

The new cartridge heater along with the company’s full portfolio of products will be on display in booth J 44 in hall 10 at K 2019 in Düsseldorf, Germany, from Oct. 16 to 23.
