Hot Runner Nozzle Heater

A forced - in brass coiled tube heater works on Joule heating. When electric current passes through the high - temperature resistant wire, it generates heat. This heat transfers to the brass coiled tube. The high - purity magnesium oxide inside has good thermal conductivity for heat transfer and electrical insulation for safety. The outer chrome - nickel steel tube reduces heat loss, and the brass tube transfers heat quickly to the object being heated, such as hot runner nozzles. If there's a built - in thermocouple, it monitors temperature, sends a signal to the control system, which adjusts power to keep the temperature stable.

Applications：

1. Injection Molding: In the hot runner system, it heats the plastic melt to improve production quality and efficiency.  In the hot runner nozzle, it controls the temperature to enhance the surface quality of the products.

2. Die Casting Industry: At the die casting nozzle, it preheats and keeps the molten metal warm to improve the molding quality.  It preheats the die casting mold to extend its service life and enhance the precision of the die castings.

3. Packaging Machinery: In the edge sealing equipment for plastic films, it heats the edge sealing part to achieve sealing.  In the heat shrink packaging machine, it heats the shrink film to wrap the products.

4. Other Industries: It heats and insulates the fluid in the pipeline transportation system of industries such as chemical engineering and petroleum.  It provides heat for processes like hot assembly and hot straightening.

Features：
