Suitable for
Projects that match this page decision
- Approved screw caps for still-water PET bottles
- Projects that can provide production cap samples
- Machine scopes with a clearly defined cap-loading boundary
Zone 03 / closure control
Bottle Cap Feeding and Capping System
The capping zone depends on the actual cap, neck finish and cap-handling route. Cap diameter alone is not enough to approve a sorter, chute, placement point or capping result.
Answer first
Provide cap drawings and physical samples before the cap-handling equipment is finalized. The proposal should distinguish the cap elevator, sorter, conveyor, chute, placement mechanism and capping heads instead of hiding them under one line item.
Not suitable for
Boundaries that need a different platform or review
- Unverified closures selected after machine production
- Crown caps, can ends or returnable-barrel closures
- Projects requiring an undisclosed or universal capping torque
Inputs required
Evidence to provide before confirmation
- Cap type, material, diameter, height and drawing
- Matching bottle neck finish and samples
- Cap loading method and operator access
- Required rejection or detection scope
Machine function
What happens at this machine or decision boundary
- Bulk caps are elevated or supplied to the sorting system.
- The sorter orients caps and sends them through the conveying path.
- Caps are placed and tightened on supported bottles before discharge.
Configuration decisions
Options that must appear in the proposal
- Elevator and sorter inclusion
- Chute route and machine-side buffer
- Capping head and adjustment scope
- Missing-cap, cap-path and jam detection
Interface requirements
Upstream, downstream and utility handovers
- Confirm where the operator or upstream system supplies caps.
- Coordinate cap demand with machine speed and buffer capacity.
- Define outfeed inspection or downstream cap checking responsibility.
Buyer risks
Questions to close before order
- Cap jams from shape or surface differences
- Tilted or missing caps caused by poor placement control
- Leakage or damage when bottle-neck and closure data do not match
FAT checks
How to verify the agreed basis
- Run only approved production-representative caps.
- Record missing, tilted, damaged and leaking closures.
- Check cap-starvation, jam alarm and restart logic.
Quotation scope
What the commercial offer should state
- Cap elevator, sorter, conveyor and chute
- Capping-head count and change components
- Approved cap and bottle-neck references
- Detection, FAT method and spare parts
