We provide custom-built roller die liner machines for cap lining with all types of closures. As a trusted cap lining machine manufacturer, we ensure that liner materials, fed with reels into the machines, are precision cut to specific patterns using specially designed roller dies. Our roller dies can cut flat, round shapes from rolls of cap lining 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. Each lining machine is available with vibratory, waterfall, or centrifugal feeders, and in-line tracks for continuous flow of parts in the production line. If required, die-reelers, motorized stock feeders, automatic changing and loading of liner material, scrap re-reelers, or choppers can also be added. Our closure lining equipment can be integrated with secondary closure processing equipment such as closing or assembly cap machines.
Tooled for 1, 2, 3, 4, or 6-up configurations, the rotary die we use cuts with ease and only requires reduced maintenance. Station tooling mounted to 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 closure lining machine, our customers can expect longevity and reliability due to our use of mechanical and servo-driven motions. Our skilled workforce is all under one roof, allowing for 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. Our range of closure lining machines ensures precise and consistent performance, meeting the highest standards in the industry.
