Hot Runner Heaters & Brushes

HEATTEC hot runner heaters are made of nickel chrome resistance wire placed inside chrome nickel steel tube filled with mgo powder and compacted for faster and efficient heat transfer. The heaters are annealed to acquire malleability for bending into any shape. Hot runner heaters with built in thermo couple are also available. Hot runner bushes are produced with hot runner heaters of different cross section with inner brass and outer stainless steel cover.

<p style="text-align: justify;">HEATTEC Low Density Catridge Heaters are made of helically wound nickel chrome resistance wire evenly stretched and placed in ceramic insulators. The elment assembly is inserted into Brass/SS 304 tube. High grade MgO powder is filled in the remaining space inside the ceramic insulators to increase thermal conductivity, dielectric strength and heater life.</p>

<p style="text-align: justify;">HEATTEC High Watt Density Cartridge Heaters are manufactured with most advanced technology and quality raw materials, enables usage with high watts in small spaces and advanced manufacturing process ensures our heaters are vibration proof and thus ensures excellent reliability in heavy duty working conditions (Like Plastic Processing, Printing, Packaging and automobile industries where the heaters are subjected to heavy vibrations). The high performance is achieved by correct installation of the cartridge heaters. The perfect fitness of the heater in the hole facilitates good heat exchange between the surfaces of heater and mass to be heated thus increases the heater life and reduces energy loss.</p>
