Maschine shut-off nozzle, type NE Application: Elastomeric plastics (including L.S.R. - Liquid Silicone Rubber) Shut-off technique: Needle shut-off with Integrated two way pneumatic actuator Index of contents Chapter www.herzog-ag.com [email protected]

Maschine shut-off nozzle, type NE Description The pneumatically controlled nozzle type NE has a needle shut-off mechanism which stops the melt stream directly at the mold interface. Rubber, liquid silicone rubber and other elastomers can be processed without fear of premature vulcanization due to the nozzle's integrated cooling system, which uniquely regulates temperature through the entire nozzle. The nozzle can also be fitted with an interchangeable diving tip for cold channel applications. The type NE nozzle is suitable for processing with injection pressures of up to 3,000bar and an injection...

Maschine shut-off nozzle, type NE Tip with radius or angle → nozzle arrangement with hot mold separation For mold plates with thermal separation between sprue bushing and nozzle. The nozzle should shut as close as possible to the cavity. Cooling through the entire immersion length is required. Tip contour and orifice are manufactured to customer specifications. The nozzle tip lies against the hot mold and is tempered (cooled). Premature vulcanisation is therefore eliminated. The thermal separation occurs between the mold and the cooled nozzle. cooling Conical tip for cold channel → nozzle arrangement...
