Electric Heater Ceramic Brass Mica Band Heater for Injection Molding

Introduction:

Brass nozzle band heaters are completely against external agents such as melted plastics.

They are very resistant to wearing and shocks.

High watt-density per square centimeter allows a fast and safe reaching of required working temperature.
Brass nozzle heaters are submitted to extremely high pressure that ensure high insulation, excellent thermal exchange, lack of internal voids, perfectly smooth contact area for an optimum and uniform heat transfer to every part of the nozzle.

Characteristics

• Sealed band heater in brass, with folded ends
• Band heater connection, waterproof technology
• Electric insulation by mica plate
• Connection: nickel core, fiberglass insulated + earth wire; protected by a galvanized steel braid
• Max. watt density : 5 W/cm² (Wattage tolerance: +5% -10%)
• Diameter: 25 to 150mm
• Height: 25 to 70mm
• Max. operating temperature over the surface of the heater: 340ºC, depending on working conditions.
• Brass sealed nozzle heaters can be supplied with a built-in J-type thermocouple.

Applications:

FLAT: Dies, Platens, Moulds, Tanks, Process Machinery, any application where controlled surface heating is required.

BAND: Dies, Cylinders, Drums, Tanks, Injection and Blow Moulding Machinery and Plastic Extruders.
