Provided Cast In & Pressed-In Brass Coil Heaters are known for higher temperature nozzle heating applications. These heaters windings have been appreciated to shift in the direction of the pour-which creates variability from heater to heater. Further, offered heaters is widely used in immersion applications or available with us in all the standard sizes or can be customized as per the specific demand of our valued customer. Further, offered Cast In & Pressed-In Brass Coil Heaters improves quality, reduces cycle time and extends the range of plastic that can be run on a hot runner system.
Suwaie Heaters' pressed in brass coil heaters deliver the benefits of cast in brass coil heaters and eliminate known problems associated with the casting process. Originally designed for the mass spectrometry market, SUWAIE pressed in brass coil heaters have measured 8% faster responding than cast in brass heaters. The machined path in the brass for the heater enables exact repeatability of heat profile. By never exposing the coil heater to molten brass there are no risks of shifted heater coils, or destruction of the thermocouple junction.
