Nozzle/Slip-on Heaters
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 you require high performance, high temperature or high watt density Watlow has the heater to best fit your application. Watlow's family of nozzle/slip-on heaters include, THERMASLEEVE™ nozzle, MI nozzle, syringe, thick film cylindrical, mica nozzle, coiled nozzle, mini-coil nozzle and metric mini K-RING® nozzle heaters.
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. The patented manufacturing technology features a computer-controlled laser cutting technique that precisely generates the power distribution pattern. The heater is 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.
THERMASLEEVE nozzle heater benefits:
- Rapid thermal response
- Precise temperature profile
- Low physical profile
- Precision fit
- Repeatability
- Optional external thermocouple
- Easy installation and removal
