Hot runner coil heater look

Hot runner coil heater size


1. Hot runner heaters are made of nickel chrome resistance wire placed inside chrome nickel steel tube filled with MgO powder and compacted for faster and more efficient heat transfer. Hot runner coil heater is widely used in heating engineering, mold, plastic industry, including the transfer machinery, medical equipment, casting process, welding, heat treatment process and many other industries and fields.
2. Length of Hot runner heater within 20-3000mm is mainly used for hot runner mold or, as well as other precision heating system. Spring heating ring external using high quality Ni-Cr steel tube, the internal use of high purity magnesium oxide , high temperature resistance wire, and first-class manufacturing technology.
3. This hot runner heater has a simple structure, but it is more various in usage.
4. They are produced with hot runner heaters of different cross section with inner brass and outer stainless steel cover.
5. The heater coil can fastened to the machine or electric heating implement directly, or inserted into mold or hole in the heating board, in this situation, the heater can get exact and high efficient heat source, eliminate the lost of heat and make sure the heat would be adopted by the mold or heat board, then it can reach the goal of saving energy.
6. It has the advantages of high thermal efficiency, good mechanical strength, safe, reliable advantages.
7. The position of joint is extremely stable, and never flying-off, and it is available for 2 to 5 years in a suitable situation, and is widely used for heating water, oil , nitrite, acid and lower melting temperature metals.
