The new Rheo-Pro N08 Star Gate hot runner nozzle from Mold Hotrunner Solutions Inc., designed for high cavity molds that require multiple side gating into the walls of the cavity, is a robust solution for 24/7 high volume production.

Ideal for long and tall tubular parts such as syringe barrels and medical applicators, the four tip side-gate method completely eliminates the costly cold runner material that is typical for such parts.

With easy mold integration and mold maintenance, the Star Gate nozzle performs best in molding applications with PE, PP and other non-sensitive materials that offer a wide processing window in terms of melt residence time or dwell time.

The unique nozzle design reduces the mold cost significantly in comparison to other more cumbersome side gating methods, such as disks, where the cavity inserts must shift towards the nozzle tip, creating an unnecessarily complicated hot runner assembly.

A Star Gate nozzle can distribute melt to four cavities through a small hot tip side-gate of 0.8-mm diameter (. 032 inches) with a gate-to-gate spacing of 52.0 mm (2.047 inches). This spacing allows for efficient mold cooling to lower cycle time. Subsequently, the cavity plate and cavity inserts maintain good structural mold strength.
