Screw capping
Spindle, chuck or servo heads tighten threaded caps to a set torque.
Capping Machines for Industrial Packaging Applications
Apply and tighten screw, ROPP, press-on and lug closures.
A capping machine places and secures a closure on a filled container. Screw caps are tightened to a set torque, ROPP caps are rolled onto the thread, and press-on or lug caps are pushed or twisted into place. Torque control and container grip matter as much as speed.
Types and configurations
Common approaches in this category. The right one depends on your product, pack and output.
ROPP capping
Roll-on pilfer-proof heads form an aluminium shell onto the bottle thread. Common for pharma syrups and spirits.
Press-on capping
Snap caps, plugs and dispensing closures are pressed down by a belt or plunger.
Lug capping
Quarter-turn lug closures for glass jars, often used with vacuum or steam in food.
How to choose
| Selection factor | Why it matters |
|---|---|
| Cap dimensions | Diameter, height and thread type decide head size and change parts. |
| Torque | Too low leaks, too high cracks caps or makes them hard to open. Ask about torque setting and checking. |
| Feeding method | Bowl feeders, elevators or pick-and-place suit different cap shapes, such as trigger sprayers and pumps. |
| Container stability | Tall, light or oval bottles need neck or body gripping to stop rotation. |
Where it fits in a packaging line
A typical sequence. Your actual line depends on product and pack.
- Filling
- Cap feeding
- Capping
- Induction sealing
- Labeling
- Inspection
Technical specifications such as output, accuracy and dimensions are configuration dependent. They are confirmed against the supplier datasheet for each enquiry.

Frequently asked questions
How do I choose between a chuck capper and a spindle capper?
Chuck cappers grip the cap and apply torque in one head per station, which suits a wide range of caps and accurate torque. Spindle cappers use pairs of rotating discs and suit continuous, faster lines with standard round caps. Trigger sprayers and pumps often need chuck or pick-and-place designs.
Can a capping machine handle trigger sprayers and pumps?
Yes, but they usually need special cap orientation, feeding and head tooling. Share samples so the supplier can confirm feeding and tightening.
Do I need torque checking?
If leak complaints, tamper evidence or ease of opening matter, offline or inline torque checking is worth discussing.
