4.2×2.2 Spring Coil heater is made of high-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 thermocouple can be built in the heater according to customer’s needs.Intergrated thermocouple can ensure accurate temperature control.
Using high-strength protective casing to the heater leads to be effective protection, the highest temperature casing up to 200 ℃, pressure up to 1.5kV.
It is widely used in the plastic industry, packaging machinery, medical equipment, casting technology and other electric heating industry, especially for hot runner mold system to provide high-performance electric heating.
