Sealed Nozzles | Industry Sectors | Swift Heat & Control

Sealed nozzles are manufactured in either mica or ceramic. Mica sealed nozzles are available in either brass or stainless steel depending on the application. It is recommended to use stainless steel nozzles where moulding or extrusion of PVC is used in the process. Ceramic nozzles are high watts density heaters and should be used where higher melt temperatures are required such as in nylons and acetyls.
Correct fitment and tightening up of these heaters is critical to ensure not only excellent heat transfer but also longevity and usage. Plastic spillage onto nozzle heaters should be avoided as this tends to suffocate the heater which may result in element failure. Good housekeeping practices are advised at all times .
