产品概述

Coil spring heater with cross section of 3*3mm is made of quality stainless steel, German heating wire, American high-purity magnesium oxide and strict technology, manufactured by automatic devices with independent intangible intellectual property rights. It could be used in the temperature as high as 650°C. And K, J or E type temperature control thermal couples can be built in the heater according to customers’ needs. Integrated thermal couples can ensure accurate temperature control.

It adopts two-end intense wound form. It could be used in casting technique and other electric heating industries, especially as hot runner mold system to provide quality electric heating.
