Watlow offers a full line of hot runner nozzle heaters for the plastics industry as well as slip-on heaters for the medical and analytical industries. While every heater has a unique set of capabilities, each nozzle heater is designed to meet specific application requirements. Whether an application requires high performance, high temperature or high watt density Watlow has the heater to fit the application.
The Watlow pre-coiled, cable nozzle heater has been formed into a compact, tightly wound coil to supply 360 degrees of heat. This nozzle heater features a 5 in. (127 mm) long, no-heat tail section, which eliminates failures in the adapter area due to overheating.
This cable nozzle heater is manufactured with Watlow’s swaged compaction process. This process provides a greater compaction of the MgO insulation than the competitor’s rolling process. Compacting MgO insulation into a solid mass results in excellent heat conductivity and high dielectric strength.
