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.
