Watt-Flex® Cartridge Heaters use a continuous coil construction that can deliver either full or reduced power at the tip to suit your process heating application.  A unique feature of the Watt-Flex® Cartridge Heater design is our ability to offer a HOT TIP option.

Used in injection molding heat probes, for example, the Watt-Flex® HOT TIP option can minimize undesirable gate freeze-off.  The HOT TIP has also been utilized in branding, plastic perferation and process applications where heat is required at the tip of the heater.

Conventional heater designs prohibit heated tips:


Watt-Flex heaters, however, can be constructed with hot or cool tips by either concentrating or stretching the continuous coil inside the densely compacted MgO dielectric as shown below:



A Watt-Flex® HOT TIP should be used in applications where the cartridge heater can be fully seated within an enclosed bore. We also offer flanges and mounting bracket options to help achieve and maintain end of bore contact.
