- Technical Specification
Anupam’s 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, Anupam’s 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.
Flexible design options include internal, external "wound in" or external slotted type J or type K thermocouple
For OEM applications Anupam can heat profile a Pressed in Brass Coil Heater specifically to your nozzle.
Features & Advantages
- Flexible cold section
- Higher Watt Density than a Coil Heater
- Resistance wire centered for more repeatable heat profile
- Sealed transition head for moisture resistant applications available
- Quick Heat Dissipation, High Insulation, Extended service life of heater.
- Can be built with a micro, mini, flat, low profile or round coil heater.
- Faster responding heater due to eliminated air pockets than Cast in Brass Nozzle Heater
- Profile and heater orientation precisely repeatable
- Improved Durability as Thermocouple is not exposed to molten brass temperatures
- Potential for designing thin walled brass heaters to minimize OD impact
- Precision fit on Hot Runner Nozzles
- Highly Non-corrosive
- Maximum heat transfer due to more contact area.
- Robust Design with Choice of Terminal Exits
- Various Watt Density options available
Applications
- Injection Molding
- Mass Spectrometry
- Air Heating
