Collapsing Core Closures

Injection Mold | Collapsing Core Closure Molds | StackTeck

Collapsing Core Closure Mold technology enables the molding of creative packaging solutions, including 360 degrees of internal threads or undercuts as well as containers or closures with smaller neck diameters than the core or body (e.g., cosmetic jars). These capabilities enable the injection molding of part designs that would traditionally have been molded via injection-blow or extrusion-blow methods.

Collapsing Core Closure Mold technology opens the window for injection molded parts typically molded via injection-blow or extrusion-blow methods. Benefiting in better quality parts, customers can also benefit from reduced part weight, improved cycle time (three fold), and increased productivity.

The potential for mold wear is eliminated due to robust wear backing plates and non-reliance of frictional forces during the collapse of the core inserts. All components are water cooled to achieve minimal cycle times.

StackTeck’s has built collapsing core molds with over 2000 cavities.
