...the new generation


Needle shut-off (NSO) nozzles are used to process thermoplastics and liquids. Clean shut-off of melt and reliable closing during metering are the functions of an NSO nozzle. With the shut-off nozzle SYSTEM ENG was realized a professional single hole NSO, that meets all requirements for a trouble free and economic production of injection moulded parts.

The Needle shut-off nozzles SYSTEM ENG are obtainable in two types:

Type S, spring operated Type L, power operated
