Description of 
24v 4mm Cartridge Heater
Cartridge Heaters are used largely used to heat liquid, solid or gas, the application in plastic industry is very wide, such as hot runner system,small mould heating ,plastic package ,Medical equipment plastic ,plastic injection molding machine nozzle heating, Package and cartridge is also used in the cigarette industry, footwear industry, thermoforming machinery. Small cartridge heaters are largely used for heating 3D printers, which has high wattage density, and could heating up fast and efficiently. We could make the cartridge heater as small as 4mm in diameter, 15mm in length, voltage from 6v to 480v. Wattage density could be as high as 20w/square cm.
High-wattage cartridges belong to a new generation of electric heating elements; they make it possible to use high watt loads in small spaces, thus ensuring excellent reliability in heavy-duty work conditions. Their special construction technology makes them the most advanced type of heating elements. The entire length of the wire wound around a magnesium oxide core is in a faraway position from the axis of the cartridge, very close to the metal sheath, with a very thin and compressed insulating wall in between; this allows excellent heat exchange that allows a much lower temperature of the resistance wire than in other heaters in which the wire is in a deeper position. Besides the use of advanced technology and precise inspection techniques in their manufacturing, Ultramar cartridge heater owe their total reliability to the use of first-class material from the best sources in the market.
