Flexible Hot Runner Manifold Tubular Heater For Injection Molding Machine

Hot Runner Manifold Tubular Heater For Injection Molding Machine

Description 

Hot Runner Manifold Tubular Heater also known as Formed Tubular Heaters or Flexible heaters, these heaters are mainly used for heating hot-runner manifolds for injection-molding plastics. The tubular heater can be precisely press-fitted into a milled slot or manually hammered in with a plastic hammer and without special tools. By taking into account the recommended slot dimensions, a contact surface of up to 75 percent can be achieved for optimum heat transfer — for both round and square formats.
A superior grade of helical wound high temperature resistant NiCr alloy heating wire is swaged in Chrome Nickel Steel sheathed tubes. The insulation consists of superior grade of magnesium oxide (MgO). Threaded terminal post which gives a cold section of approx 40mm (min) are sealed with special sealing components to prevent the heater from moisture. These are then formed to shapes as required to press fit in the hotrunner manifold which dissipated even heat transfer to the hotrunner mould.
For manufacturing manifold tubular heaters it is necessary to provide an accurate dimensional sketch showing all centre distances, bending radius and path.
