Stainless Steel Armored Electric Coil Heaters , Electric Heating Element
Stainless Steel Armored Electric Coil Heaters With Cap And PTFE Insulated Leads
1. Brief Introduction
Our coil heater made of Germany heater wire ,the united states high-purity magnesium oxide materials and strict process technology,there are various sections and sizes,square ,round and flat cross sections and sizes available ,provide high –performance electric heater for heating hot runner mold and other fileds. Heaters maximum temperature up to 700C.The integration of temperature thermocouple for precise temperature control ,can provide K J E themocuple ,blasting and black surface treatment ,also provides bright surface.
The materials used direct the heat inward toward the nozzle resulting in a very efficient heater with even heat distribution. The tightly toleranced I.D allows a slip fit with no clamping required. The Armored Nozzle Coil Heater are constructed with a Stainless Steel inner sleeve and a Stainless Steel outer sleeve. The heater is tightly sandwiched between these sleeves eliminating the heat transfer problems associated with other dual sleeved designs.
