10mm-38mm Nozzle Copper Hot Runner Coil Heater for Extrusion
Machine
1. Coil Heater Brief Introduction
Cable heaters could be coiled to form coil heaters that are ideal
whenever a large amount of heat is required in a confined space.
Coil heaters have many applications but are mostly utilized as
powerful heating cells inside hot runner nozzles in plastic
injection molding.
Coil heaters are high performance mini tubular heaters that have
small rectangular, square or round cross sections that are flexible
and can acquire different shapes and configurations.
Coil and cable heaters can accommodate "J" type or "K" type
thermocouple sensors that could be placed internally at the tip or
the middle of a heater. They can be made as well to have profiled
or distributed wattage configuration.
The sheath material of standard cable heaters is stainless 304;
their heating core is coiled or straight solid Nickel Chrome wire.
Cable heaters can transmit up to 35 W/in2 heating capacity and can
attain up to 15000F surface temperature.
