Manifold Tubular Heater Description: Also known as Formed Tubular Heaters or Flexible heaters, these heaters are mainly used for Hot Runner manifolds.
PHP Manifold heaters are designed and manufactured with 40 years of experience, for superior performance and life expectancy to withstand high sheath temperature and provide the best combination of physical strength, high emissivity & good thermal conductivity to heat hot runner manifolds.
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.
