Hot runner coil heater nozzle heater with thermocouple
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.
