Hot runner heating tube is made of high-quality stainless steel material and strict process technology. Hot runner coil heater heating tube has round, square and flat sections. There are 2 options for outer surface: bright and sandblasted. Also, it can be made with J type or E type temperature control thermocouple.

Usage of Hot rubber coil heater:
Hot runner heating pipe is widely used in hot runner plastic molds, blow molding machines, extruders and hot nozzles
All the hot runner electric heating elements of our factory have withstand 1000 ° high temperature carbonization treatment in the high temperature annealing furnace. The surface of the final products are dark green and have good flexibility. They can be wound and arbitrarily bent by customers requirements. It is flexible and convenience for hot runner manufacturers. Thus, the contradiction caused by the outer diameter, length and specifications of standard or non-standard hot nozzles (runner sleeves, nozzles) is solved.
