Straight hot runner heater
    Straight hot runner heater

Product Description:

- Description:

The hot runner heater is mainly used for hot runner mold or, as well as other precision heating system. Generally the length 20-3000mm, Spring heating ring external using high quality Ni-Cr steel tube, the internal use high pure magnesium oxide, high temperature resistance wire, and first-class manufacturing technology. The wire is annealed, with flexibility can be bent into an arc or circle heating. Its high working temperature, fast heating, uniform heating precision, long service life, can be automatically controlled area, high thermal conduction, if internal heating material damage, the external can be reuses.


Hot runner heater is an advance concept of thermal engineering which has a construction similar to high watt density cartridge heaters. These heaters are also known as high performance tubular heaters or cable heaters. The basic construction of these heaters consists of compacted MgO, high temperature resistance wire and Chrome Nickel Steel tube. These heaters can be constructed with or without built in thermocouples. They are usually installed where space available for heating is limited, and are widely used on hot runner nozzles, and manifolds, die cast nozzles, packaging machines etc.

Hot runner straight heater resistance wire:

1) It has a simple structure, but it is more various in usage.

2) It can be bended to any shapes, 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.

3) Besides, straight item has the advantages of high thermal efficiency, good mechanical strength, safe, reliable, sensitive advantages.

4) 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.
