Hot Runner Electric Coil / Spring Heaters With Silicone Vanished Fiberglass Leads
1. Coil Heater Brief Introduction
Coil and cable heaters are made by placing a pair of tiny coils or two lines of straight resistance wire inside a very dense MgO medium. This core is then inserted into a stainless steel shell. These high-performance heating cells can acquire temperatures of up to 1500° F.
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.
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.
A Coil Spring Heater in its unformed straight stage can have a maximum length of 6ft and its cross-section can be square or rectangular, while a cable heater can be 300ft long and is available in round cross sections. Thermocouple sensors could be installed internally at the tip or the middle of a heater.
