How should small vials be inspected before filling or assembly?
Define the defect classes that matter, detection capability, challenge samples, reject confirmation and handling of uncertain items. Inspection should be placed where the item is stable and defects are visible.

What should I check first?
Record the machine state and the finished result before changing settings. This helps identify where control is first being lost.
- Inspect the full range of small vials.
- Observe vial unscrambling or puck handling during bulk loading and restart.
- Record damage, orientation loss, contamination and rejected items.
- Measure representative parts or bottles from several batches.
- Record the true required feed rate plus restart and surge conditions.
- Observe the first point at which orientation or stability is lost.
Why is this production problem happening?
Work from the evidence and change one variable at a time. These are the most relevant causes to investigate first.
- Container or component tolerance exceeds the handling tooling range.
- Bulk pressure, static, damage or contamination affects separation.
- The route lacks confirmation of orientation, presence or rejection.
- The item geometry does not provide a reliable orientation feature.
- Bulk loading creates nesting, tangling or excessive pressure.
- Transfers and guides do not maintain a stable datum.
How can I correct or improve it?
Make a controlled change, repeat the same measurement and compare the result before moving to the next adjustment.
- Approve a representative sample matrix.
- Control bulk feed, recirculation and downstream demand.
- Add inspection or confirmation where the risk requires it.
- Prove feedability using production parts from normal tolerances.
- Control bulk load and provide accumulation without damaging product.
- Improve transfers, guides and positive orientation checks.
What should I send Lancing?
The most reliable recommendation is based on representative production materials and a measurable acceptance result.
- Production quantities of small vials
- Drawings and tolerance information
- Expected contamination or defect classes
- Required orientation and output
- Video of current manual or automatic handling
- Representative containers or components from several batches
- Drawings, material, weight and orientation requirement

More quick answers about this problem
What should I check first for small vials?+
Inspect the full range of small vials.
Why does this problem happen with small vials?+
Container or component tolerance exceeds the handling tooling range.
How can I improve or correct the problem with small vials?+
Approve a representative sample matrix.
Which part of the production line does this question relate to?+
This question relates primarily to bottle preparation & component feeding. It may also be affected by upstream product or pack supply and by downstream handling, so check the full production sequence rather than one machine in isolation.
What should I send when asking for a machinery recommendation?+
Send Production quantities of small vials; Drawings and tolerance information; Expected contamination or defect classes; Required orientation and output. Representative production samples and a measurable acceptance target are normally more useful than a catalogue description alone.
