Watlow introduces its new THERMASLEEVE™ hot runner professional nozzle professional heater. The 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. It was designed to have intimate contact with the surface of the nozzle, which optimizes heat transfer. This intimate contact combined with lower heater mass contributes to rapid thermal response to and from the nozzle tip. This helps reduce cycle times and ensures high quality final parts. Watlow’s patented heater manufacturing technology allows hot runner manufacturers to create precise temperature professional profiles beyond the limits of conventional heaters using their proprietary professional laser structuring, which creates a customized temperature profile within the heater. The result is improved viscosity control within the nozzle, leading to increased yield, quality and shot-to-shot consistency. The THERMASLEEVE heater is easily installed and removed from the nozzle with a custom installation and removal tool. It is self-clamping ensuring the heater is secured into position during operation. It is also designed to accommodate a thermocouple manufacturers secured to the external body of the heater. The THERMASLEEVE hot runner nozzle heater has an extremely low profile and offers high wattage in a smaller package at a comparable price to conventional nozzle heaters.
