A capping machine must handle the cap and bottle as a matched system. Closure dimensions, thread design, bottle stiffness and presentation affect the application. Send production samples of both parts before selecting an automatic capping machine.
Which closure details should be supplied?
Provide the cap type, dimensions, material and any liner or tamper-evident feature. Include the matching bottle finish and closure supplier's application guidance. Ask the machine supplier to confirm the capping method and tooling proposed for that exact combination.
Do not assume that all screw caps, press-on closures or trigger assemblies use the same machine arrangement. If you need several closure types, list each one separately and ask which change parts or alternative equipment are required.
What is included in automatic capping?
Clarify cap storage, orientation, feeding, placement and tightening in the supply scope. Ask which tasks remain operator responsibilities and how missing or incorrectly presented caps are handled in the quoted model. The machine title alone does not establish every included function.
Provide bottle height, diameter, filled weight and conveyor details. Lightweight or flexible bottles may need a different support arrangement from rigid containers. Test the least stable bottle and the closure combination most likely to challenge the line.
What should the acceptance trial inspect?
- Cap seating, alignment and visible damage.
- Closure performance using the closure supplier's agreed method.
- Bottle stability and surface marking during handling.
- Normal replenishment, stops and format changes.
How should an order be specified?
Agree the exact cap-bottle combinations, tooling, line interfaces and measurement method through technical consultation. Keep accepted samples and written settings with the handover record. Use the capping quality checklist to define the defects to investigate during production instead of relying on appearance or hand feel alone.
