Hot runner heating coil and thermocouple

Date:2013-11-25

Anole Molding-Tech can provide high quality hot runner heating coil and thermocouple with competitive price.
The heating elements for nozzle is called heating coil. It just need few minutes to heat the nozzles. Every nozzle is an independent heating area with thermocouple near the sprue gates.heating coil is usually designed to be a coil combined with two resistive heater inserted into the stainless pipe and added with magnesium oxide. The front of heating coil is unheated area with the length more than 55mm. On the bottom of heating coil, which is near the sprue gate is installed with thermocouple, with the non-heated area 10-15mm. Normally, hot runner system will use spring shape heating coil because of its highly effective heat transfer system around 25%, but actually it will reach around 20%.
Another Thermocouple is based on the thermo-electric effect to detect the temperature on nozzle. The thermoelectric force produced by thermocouple will change according to the temperature. The thermocouple has niddle shape thermocouple and rectangular thermocouple. For the thermocouple on the manifold, it is between the manifold heater and runner. When the hot runner system do the injection works, the moving parts of molds and the moving of the safe door of the injection machine will extrude the wires and the high temperature plastic material will corrode the thermocouple and make it short out.

If you have any inquiry for hot runner heating coil and thermocouple,please do not hesitate to contact me.
