Hot Runner Mini Heater With Thermocouple,Mini Coil Heaters For
Injection Molding Machine Brass Coil Heater
Description:
Coil heater is one kind of tubular electric heating elements. These
components are mainly used in aerospace, petrochemical, rubber and
plastics industries, and the like, it can be used to heat still or
flowing air, water, oil,nitrate, alkali and other kinds of liquid.
It can also be used to melt light metal or to heat metal moulds. It
has advantages such as simple structure, long heat lifetime, high
thermal efficiency, reliable and safe operation and so on.
The hot runner heaters are annealed to acquire malleability for
bending into any shape. Injection molding coil heaters with
thermocouple are also available.
