Stainless steel Hot runner system spring coil heaters for plastic injection mold

Stainless steel Hot runner system spring coil heater for plastic injection mold

Description:

Coil heater 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. The wire is after the 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.

1) Hot runner heater is an advance concept of thermal engineering which has a construction similar to high watt density cartridge heaters.

2) These heaters are also known as high performance tubular heaters or cable heaters. The basic construction of these heaters consist of compacted MgO, high temperature resistance wire and Chrome Nickel Steel tube.

3) 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.
