Closure Lining Equipment

We provide custom-built roller die liner machines for cap lining all types of closures. Liner materials, fed in reels into the machines, are precision cut to specific patterns using special designed roller dies. Roller dies in our machines can cut flat, round shapes from rolls of cap liner materials. CAM actuated slides with tooling heads transfer the shaped liner material into the closures.

Die liner machines with multiple insertion tooling can be built to fill liner material in up to 1200 closures per minute. Machines are available with both vibratory, waterfall or centrifugal feeders, and in-line tracks for continuous flow of parts in the production line. De-reelers, motorized stock feeders, automatic changing and loading of liner material, scrap re-reelers, or choppers can also be added, if required. The machines can be integrated with secondary closure processing equipment such as closing or multiple piece closure assembly machines.

Tooled for 1, 2, 3, 4, or 6-up configurations, the rotary die we use cuts with ease and needs reduced maintenance. Station tooling mounted to ground steel plates can be hardened and ground. Pinch points as well as rotating areas are guarded according to the best practice principles of machine design and OSHA standards. Perimeter guarding can be fabricated with clear polycarbonate panels as well.

From each and every machine our customers can expect longevity and reliability due to our use of mechanical and servo driven motions. Our skilled work force is all under one roof, allowing for the complete construction, and product accountability, within our shop. We use both conventional and state of the art CAD/CAM and wire EDM machines to fabricate the components.
