HR nozzle for side-gated polyolefin applications

The new Multi Shot Z10440/... from Hasco Hasenclever (Lüdenscheid, Germany) has been designed specifically for side gating and is ideal for articles such as sleeves and cannula tubes. The nozzle has been conceived specifically for application with polyolefins.

When developing this hot runner nozzle, the design team focused on creating a service-friendly unit, which provides an economical structure of the nozzle and user-friendly tool assembly. Two, four or six gating points offer the possibility of grouping cavities together economically in clusters, significantly simplifying the design of manifold tools.

Thanks to the modular design there is no need to divide the mold inserts, which makes assembly easier and lowers the cost. This is made possible by the segment-like fixing arrangement with simultaneous locking. The individual nozzle tips can be exchanged without loosening the remaining gates, even on the injection molding machine when cold.

A selection of different nozzle lengths is available to satisfy various design options. The individual lengths are coordinated to Hasco standard plate thicknesses. Thermal expansion in the overall length direction is compensated for in the nozzle cover, and through fixation of the nozzle head, precise concentric positioning in the gate is guaranteed. Good color change properties are achieved through the low melt volume in the nozzle and an undivided melt stream in the nozzle tip. —immeditorial@cancom.com
