The earliest development of the heat pipe technology is to solve the problem of the temperature difference between the surface of the satellite,which is now used for mold cooling, injection molding machine cooling in the injection molding process, extrusion screw heat. The heat pipe technology combined with hot runner technology, has the following advantages:
1. The average temperature is good, warming up quickly. Because of the heat pipe in the length direction to achieve a temperature self-compensation, can automatically adjust and improve the temperature distribution within the hot runner, temperature too quickly, usually in just 20min to reach operating temperature. 2. The heating of the hot nozzle can also be achieved, and the closer to the hot nozzle tip than the traditional heating elements. 3. without high heating power per unit volume, can operate at lower temperatures. The thermostat can reduce points, just a single point temperature in most cases, and to reduce the heating and temperature control device lines, as well as the complexity of the structure. 5. Because of the hot runner system to solve the problem of temperature uniformity, thus improving the quality of the melt, reducing the viscosity of the differences arising from the temperature difference and avoid weld lines in the flow path through the convergence of cold and hot streams generated.
