Watt-Flex heaters are constructed to deliver full heat to the tip, making them suitable for applications such as injection molding. Due to the split-sheath design, the cartridge heaters run efficiently; are easily replaced; and allow each half of the heater to expand independently when energized, ensuring metal-to-metal contact with the surrounding bore. The heaters are offered in standard diameters of 0.25, 0.375, 0.5, 0.625, 0.6875, 0.75 and 1" as well as 8, 10, 12, 12.5, 15, 16 and 20 mm in lengths from 1.25 to 72" and with operating temperatures to 1,700°F (927°C).
