Manifold Heater

Also known as formed tubular heaters or flexible heaters, these heaters are mainly used for Hot Runner manifolds.
It is supplied in Chrome Nickel Steel with nominal sheath diameter of 6.50mm and 8.00mm. Standard elements have a terminal post which gives a cold section of approx 30mm for 6.50mm and 35mm for 8.00mm.The helical wound heating wire is made of a high temperature resistant NiCr alloy. And the insulation consists of superior grade of magnesium oxide (MgO). As the heaters are swaged, even at high sheath temperature they have excellent electrical insulation and a high heat transfer. To prevent the heater from moisture the connection ends are sealed with sealing components.
For manufacturing formed elements it is necessary to have an accurate dimensional sketch showing all the centre distances, radius and degrees.
