Hot runner component heater having thermal sprayed resistive element |
摘要 |
A hot runner component for heating and directing fluid material of a melt stream to a mold cavity is provided. The hot runner component includes a body having a fluid passageway therein for conveying the melt stream and a heater for heating the melt stream as the melt stream passes through the fluid passageway of the body. The heater includes a core arranged in surrounding relation to the fluid passageway of the body, a thermally-sprayed dielectric substrate layer on the core and a thermally-sprayed electrical resistance element layer overlying the dielectric substrate layer. The resistance element layer forms a discrete pattern. The heater further includes a thermally sprayed dielectric overlay layer that overlies a substantial portion of the resistance element layer.
