Capping machinery

Match the closing operation to the package, then define a trial that covers the whole line.

Start with the closure action. A pre-threaded screw cap, a press-on closure and a roll-on wine cap require different ways of applying force. A machine description alone cannot tell you whether a particular bottle and closure will seal. Before comparing offers, identify the cap geometry, the bottle support and the checks that will decide whether a trial passes.

Choose a route

Starting point	What to check
Selecting a machine	Use the cap, neck finish and closure method to narrow the mechanism before discussing output.
Changing a dispenser	Treat a new pump as a package change requiring drawings, handling trials and functional checks.
Adjusting a roll-on head	Set top-load pressure, thread-forming rollers and pilfer-proof tuck rollers in sequence for unthreaded aluminium shells.
