Watlow Cable/Coil Heaters

The versatile Watlow cable heater can be formed to a variety of shapes as dictated by its many applications. Cable heaters are small diameter, high performance units, fully annealed and readily bent to a multitude of configurations.The heater can be formed into a compact coiled nozzle heater for use on plastic injection molding equipment supplying a full 360 degrees of heat with optional distributed wattage. A straight cable can snake through a sealing bar in packaging equipment. Flat spiral configurations are used in semiconductor manufacturing while a star wound cable is used for air and gas heating.

Performance Capabilities

• Continuous operating temperatures to 650°C
• High ductility allows the heater to be cold-formed into almost any shape.
• Diameter from 0.0040" (1mm) to 0.188" (5mm)
• Internal construction options allow internal thermocouples and no-heat sections.
• Cable heaters can operate in unusual environments, including cryogenic and sub-freezing temperatures, high vacuum, and gaseous and liquid immersion conditions.

Applications:

• Plastic injection molding nozzles
• Semiconductor manufacturing and wafer processing
• Hot metal forming dies and punches
• Sealing and cutting bars
• Medical, analytical and scientific instruments
• Cast in heaters
• Laminating and printing presses
• Air heating
• Heating in a vacuum environment
