Heat Exchange Spring Hot Runner System Coil Heater With J Type Thermocouple
Description:
1) For the plastic industry for injection parts for high temperature heating, the product is made of closed stainless steel, effectively prevent leakage and damage, and the temperature is absolutely ideal for the use of units, with long working life.Coil performance advantages is in flexible installation, fast heat transfer, good insulation, production specifications from the size of the restrictions and other advantages.
2) Hot Runner Coil Heater are widely used in hot-runner molds,blow molding,extrusion and hot nozzles.The hot runner heaters are annealed to acquire malleability for bending into any shape. Injection molding coil heaters with thermocouple are also available.
