Physical samples
Send filled or representative bottles, caps, liners, pumps, triggers or ROPP closures where possible. Include both accepted and problem examples if they exist.
Trial and feeder evidence
Prepare evidence before cap-feeder and capping trials.
Better trial information helps Lancing check bottle support, closure presentation, cap feeding and line integration.
Evidence checklist
What to prepare before a capping trial.
Where no verified project trial data is supplied, the safest SEO content is practical engineering guidance. Use this checklist to prepare the material that allows Lancing to assess the closure route without inventing performance claims.
Photos and video
Show the current cap application process, bottle movement, cap storage, operator position and line layout. Short videos often reveal instability or feeding problems.
Quality criteria
Define the accepted result before a trial: torque, seated height, leak check, tamper-band formation, cap alignment or opening-force expectations.
Cap-feeder integration
Check the cap path from bulk storage to the bottle.
| Stage | Evidence to check | What it proves |
|---|---|---|
| Bulk handling | Cap samples supplied loose and in the quantities normally handled. | Whether caps nest, tangle, deform or separate reliably. |
| Orientation | Photos of cap top, underside, thread, nozzle, dip tube or trigger head. | Whether a bowl, elevator, track or pick route is feasible. |
| Transfer | Line photos showing bottle infeed, conveyor height, guarding and operator access. | Whether the cap can be placed squarely before tightening or pressing. |
| Control logic | Existing filler/labeller/coder arrangement and preferred fault behaviour. | How cap present checks, missing cap handling and conveyor stops should be integrated. |
| Changeover | List of bottle and cap formats, plus change frequency. | Whether the chosen route needs change parts, recipes, mechanical settings or separate tooling. |
Before final quotation
Do not rely on one clean product photograph.
For real production, the capper must manage normal sample variation, operator interaction, bottle movement and downstream equipment. Send several samples and describe the process around the capper, not just the closure itself.

Trial and feeder questions
Do I need to send filled bottles?
Representative filled bottles are useful where weight, balance, product residue or bottle flexibility affects capping. If the product cannot be sent, discuss an equivalent trial sample.
How many caps should be sent?
Send enough caps for assessment and repeat checks. The exact quantity depends on closure type, feeding route and what needs to be proven.
Can cap feeding be confirmed from drawings only?
Drawings help, but real caps are normally needed to check nesting, static, orientation and transfer behaviour.
What if the existing line has no drawings?
Clear photos, approximate dimensions, conveyor height, direction of travel and a short video can start the layout discussion.
Why include rejected samples?
Rejected packs help identify whether the issue is torque, cap start, neck finish, feeder orientation, bottle grip or an upstream/downstream line problem.
