230V China High Quality Hot Runner Spring Brass Coil Nozzle Heater
Heating Element
Description:
1) Hot runner coil heaters are made of nickel chrome resistance
wire placed inside chrome nickel steel tube filled with MgO powder
and compacted for faster and efficient heat transfer. The heaters
are annealed to acquire malleability for bending into any shape.
2) Hot runner heaters with built in thermocouple are also
available. Hot runner bushes are produced with hot runner heaters
of different cross section with inner brass and outer stainless
steel cover.
Specification:
1. Flexible cold section
2. Higher watt density than a cable heater
3. Resistance wire centered for more repeatable heat profile
4. Sealed transition head for moisture resistant applications
