Pressed in brass coil heater

Pressed in brass coil heater

Due to thermal expansion, The top and bottom of the coil heater tend to lift from the nozzle body after long-term operation, Hasteco solve this problem by improve the way coil heater locates in a nozzle, That’s Pressed in Brass coil heater, which is widely used in high-end hot runner systems

  • Hasteco Pressed in Brass coil heater delivers the benefits of an even heater transfer over the whole length of the nozzle because Copper has good thermal conductivity
  • Press in brass coil Heater provides faster response and longer thermocouple life than traditional “cast in brass” designs due to the elimination of Molten brass temperature and air bubbles during the casting process.
