Hot runner brass pipe heater nozzle heater pressed with coil heater
for plastic injection molds
Description:
1) Hot runner heater are made of nickel chrome resistance wire
placed inside chrome nickel steel tube filled with MgO power and
compacted for faster and efficient heat transfer. The heaters are
anneale to acquire malleability for bending into any shape. Hot
runner heaters with built in thermocouple are also avaiable. Hot
runner bushes are produced with hot runner heaters of different
cross section with inner brass and outer stainless steel cover
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)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, high thermal conduction, while
internal heating material damage, external can be reuses.
