Hot side gating saves resin and cuts cycle times

One of the highlights at NPE2012 will be brand new hot runner side gating systems for deep-draw medical parts such such as pipettes and syringe barrels.

Husky Injection Molding Systems (booth 3763) will be showing the Ultra SideGate hot runner that was introduced at the Fakuma International Trade Fair in Germany last October in a mold designed and built by Tech Mold running polyoxymethylene (POM) resin producing a 0.5 gram medical cap with 1.25 millimeter wall thickness.

Mold-Masters (booth 4463) is launching its new side gate product at NPE2012.
Melt-Cube is a new linear side gating system that permits 20% greater pitch density than circular systems. It's designed for easy tip replacement in the press. The patent-pending designis said to produce faster cycles, pristine gates and more accurate in-mold labeling (IML) molding conditions because of an additional temperature control zone at the gate. Mold-Masters said it also yields a greater level of flow balance with its proprietary iFlow manifold brazing technology. 

CBW Automation (booth 3169), will be running the Melt-Cube in a 16-cavity automated system producing a 5-6cc polypropylene (PP) medical syringe with IML.
