Why is applying synthetic corks too slow?
Practical guidance for synthetic corks: separate true machine speed from waiting, handling, replenishment and short stops.
Direct answer
For synthetic corks, count good packs over a representative production period before changing several settings at once. This is a closure application where presentation, alignment, engagement, application force or torque, liner contact and container support determine performance for synthetic corks. Application force, container support and finished-pack integrity must be tested with production samples.. Use representative product and packaging, keep the order of results and identify the first point where the process moves outside the agreed limit. Then make one controlled change, repeat the same test and compare sustained good output rather than a single successful pack.

What usually causes this?
- the machine is starved or blocked by another operation
- manual loading, unloading or replenishment extends the effective cycle
- short stops are not recorded and therefore appear as low speed
- settings are reduced to protect an unstable product or pack
- the equipment or method is not configured for a closure application where presentation, alignment, engagement, application force or torque, liner contact and container support determine performance for synthetic corks. Application force, container support and finished-pack integrity must be tested with production samples.
Checks to make in order
- Count good packs over a representative production period
- Time each operation including manual handling
- Record blocked, starved, stopped and running time
- Check replenishment and changeover losses
- Run the hardest product and largest format
- Improve one confirmed bottleneck
- Repeat the sustained-output test
How to decide the next step
Synthetic corks is a closure application where presentation, alignment, engagement, application force or torque, liner contact and container support determine performance for synthetic corks. Application force, container support and finished-pack integrity must be tested with production samples.. Use the measurements to decide whether the next action is a material or packaging change, a setting correction, a maintenance task, improved feeding or a different machinery principle.
If the process cannot achieve the required slow output result across the full product and pack range, compare the best-matched route against a written acceptance test. Include cleaning, changeover, operator work, rejects and recovery from normal stops.
What to include in your production brief
Supplying the information below makes it easier to distinguish a setup problem from a product, packaging, feeding, maintenance or machinery limitation:
- Closure drawing and production samples
- Container neck-finish drawing
- Application and removal requirement
- Liner, wad or tamper feature
- Container height and stability
- Required closures per minute
- Samples that represent synthetic corks
- A short video of the present process and fault

The first route is the primary match for this question. Final suitability must be confirmed with samples, output, site and acceptance information.
