In Manifold Tubular Heaters the helically wounded NiCr resistance wire is evenly stretched and fitted into SS or Incoloy tube. MgO powder is filled for insulation. Then the tube is swagged and annealed thus making it a solid rod which transfers heat excellently. The terminal can be designed stud or wire type.This heaters are customised in a variety of shapes and sizes as per the requirements. For the heaters to fit exactly inside the groove diagram of curves, diameters, lengths and degree will be required.
They are used in Hot Runner Manifolds etc.
