Choose the operation before choosing the machine: pump-head feeding and placing positions the pump in the bottle, screw tightening turns the threaded closure to the required torque, and press capping pushes a press-fit closure into position. These operations are not interchangeable; one line may need more than one station.
| Closure / Required Operation | Recommended Capping Solution | Notes |
|---|---|---|
| Screw Cap | Linear Capping Machine / Swing Arm Capping Machine | For regular threaded caps on round, flat or square bottles. Confirm whether the quoted configuration includes cap feeding and placing, as well as tightening. |
| Pump Head Placement | Automatic Pump Head Feeding & Placing Machine | Feeds and places the pump head, guiding the dip tube into the bottle. It does not perform final screw tightening. Confirm pump orientation, dip-tube length and stiffness, bottle-neck clearance and the downstream tightening station. |
| Pump Head Tightening | Automatic Four-Wheel Capping Machine | For suitable threaded pump collars after the pump has been placed. Confirm wheel access to the collar, bottle holding and required torque with actual samples. |
| Trigger Sprayer | Trigger Sprayer Capping Machine | Usually requires orientation control and stable bottle holding |
| Press-fit Cap | Chain-Plate Press Capping Machine | For press-fit caps or inner plugs, not threaded closures that need torque. Confirm the required seating depth, pressing force and bottle support with actual samples. |
| High-speed Line | Tracking Capping Machine | For continuous production lines where bottles should not stop frequently |
| Wide Compatibility | Four-Wheel Servo Capping Machine | Suitable for many regular screw cap bottles with adjustable wheels |
Selection factors: cap type, cap diameter, bottle shape, thread structure, torque requirement and target speed
Common questions about this machine, answered directly to help you shortlist before talking to an engineer.
Match the closure operation: screw caps use linear or swing-arm cappers; pump heads need feeding/placing then a four-wheel tightener; trigger sprayers need orientation control; press-fit caps use chain-plate press capping. One line may need more than one station.
Pump-head bottles need an automatic pump-head feeding and placing machine first, then a four-wheel servo capping machine to tighten the collar. Confirm pump orientation, dip-tube length and the downstream tightening station.
For continuous lines where bottles should not stop frequently, a tracking capping machine keeps pace without repeated start-stop, improving throughput and cap alignment.
