The inner-wire single-head heating pipe adopts stainless steel SUS304, 316, incoloy800, etc. as the surface sheath of the heating pipe; the insulating magnesium oxide powder with the advantages of good thermal conductivity, high temperature resistance, good insulation performance, etc., nickel-chromium alloy heating wire is used as the hair heating stuff;
The internal wiring single-head heating tube is made fine, and it is directly led out from the inside of the heating tube by a high-temperature wire resistant to 450 degrees. Compared with the ordinary single-head heating tube, the internal wiring single-head heating tube port portion does not adopt the terminal connection method, so that it has high high temperature resistance and strong mechanical properties, and is suitable for the embedded of the mold. When heating and vibration are large. At the same time, the surface load of the single-head heating pipe of the direct outlet is 25W per square centimeter.
