Thin Heating Cartridges Offered in Miniature Formats 

Thermodynamics specialist Hotset America Corp. presents its high-performance heating cartridges in miniature format for hot runner systems. With a diameter of only 1/8" (3.1 mm), the hotrod type HHP is said to take up no more space than a matchstick. Just as important is its heating performance, which, depending on the application, can reach up to 750°C, according to the company. As a result, the ultra-thin cartridge is recommended for technical applications in which high temperatures have to be applied and generated in a target-oriented, highly accurate manner in restricted spaces.

Hotset says the miniature heating cartridge has earned its first spurs in the field of microdosage. It promotes the flowability of adhesives through the temperature control of very narrow application valves. Adhesive marks realized with hotrod type HHP are reported to be smaller than a nanoliter — Hotset notes that approximately 50,000 of these points would fit into a single drop of rain. Other applications where small quantities of liquid substances have to be temperature-controlled for process reliability, or where solid materials have to be liquefied, the miniature heating cartridge is said to be considered a well-suited solution. This is the case, for example, in medical technology, 3D printing and in the lubrication industry.
