Compact yet functional designs are a necessity for stack mold applications. Common valve gate designs require that cylinders that operate the valve gate to be off-set in order to reduce stack height dimensions. Still this design generally results in larger molds and perhaps injection molding machine size. INCOE®’s (Troy, MI) new back-to-back design eliminates the offset requirement while making no compromise in stack height and presents the potential for cost savings in mold construction.
