Nozzle Heater For Hot Runner Systems

Watlow's Thermasleeve nozzle heater is a low profile, high-performance electric heater with rapid thermal response that allows the heat to be created precisely where it is needed. The patented manufacturing technology features a computer-controlled laser cutting technique that precisely generates the power distribution pattern. This heater with its unique technology offers energy savings of 20 to 25% over conventional cable and cast nozzle heaters. It is designed to have intimate contact with the surface of the nozzle, which optimises heat transfer. This intimate contact combined with lower heater mass contributes to rapid thermal response to and from the nozzle tip, and helps reduce cycle times and ensures high quality final parts. Thermasleeve heater is easily installed and removed from the nozzle with a custom installation and removal tool. The heater is self-clamping, which ensures the heater is secured into position during operation. This easy installation and removal reduces down time for mould maintenance and could allow a heater to be reused. The heater is also designed to accommodate a thermocouple secured to the external body of the heater. It is slotted to accommodate commercially available, off-the-shelf, thermocouples. This may mean that a thermocouple groove does not need to be machined into the nozzle. This hot runner nozzle heater has an extremely low profile. It offers high wattage in a smaller package at a comparable price to conventional nozzle heaters. Benefits: rapid thermal response; precise temperature profile; low physical profile; precision fit; repeatability; and energy savings of 20 to 25%. Applications: hot runner moulds; syringe heating; and analytical instrumentation.
