There are many types of automatic capping machines, each with its own strengths and weaknesses depending on the application. The Automatic Inline Capping Machine places and tightens at speeds up to 200 cpm with limited change parts. An Automatic Chuck Capping Machine is slower and more costly with multiple change parts, but extremely reliable and repeatable. An Automatic Cap Placer provides for an economic solution to large caps with diameters greater than 80mm that must be vertically placed to prevent cross threading on the container. The Automatic Snap Capping Machine is specialized to the application of NEPCO or similar type of snap caps with no threads. An Automatic Cap Tightener made by us does not place the caps on the container; rather it is used only for tightening or retightening after cap placement or pumps and spray heads placed by hand.
Capping machines are used for the application of plastic and metal threaded caps as well as plastic snap caps, some fitments and some types of corks and plugs. Capping is usually the most difficult aspect of a liquid packaging line for several reasons. Sometimes the range of geometries and sizes of caps and bottles is so wide that the capping machine components become expensive or the platform of that particular type of capping machine is not suitable for all sizes and geometries in the range. Sometimes the bottle and cap combination are not ideal with the threads of the bottle being in conflict with the threads of the cap and great force is needed to apply the cap. Sometimes caps can only be placed vertically on the container which increases the capital cost of the machinery. Inline Filling Systems understands these issues very well and has a capping machine to address every one of these capping challenges. We specialize in capping machines and cap feeding systems for both startup companies as well as higher speed production environments.
NPACk manufactures and supplies a range of capping and closing machines to suit a wide range of bottles, caps and closures. From simple hand held cap tightening tools through to fully automated cap sorting, placing and tightening systems, we have solutions for pre-threaded screw caps, ROPP caps, valve crimping and press-on caps. If you cannot find a suitable machine in our standard range, please contact us to discuss your individual requirements – our engineering team is on hand to discuss modifications or even bespoke machine design solutions.
