01
Thread engagement
The cap must start correctly before tightening. Cross-threading risk increases when caps or bottles vary, when bottles are unstable or when cap presentation is inconsistent.

Threaded Cap Capping Machine
Threaded cap capping machines tighten screw caps onto matching bottle or jar threads. The process looks simple, but performance depends on closure quality, torque, cap start and bottle control.

Buying detail
Important points before you shortlist a machine
02
Torque and liner compression
Threaded caps with liners need enough torque to seal without damaging the liner or making the pack hard to open.
03
Selecting the automation level
Semi automatic routes are useful for smaller batches. Automatic and spindle routes become more attractive as output and consistency requirements increase.
Send your bottle, cap and output details to Lancing UK.
Include cap diameter, closure type, bottle size, target output, available space and whether the capper needs to connect to filling or labelling equipment.

FAQs
Questions about threaded cap capping machine
What is a threaded cap?
A threaded cap screws onto matching threads on a bottle, jar or container neck.
What causes cross-threading?
Misalignment, poor cap start, bottle movement or unsuitable cap presentation can cause cross-threading.
Can threaded caps be tightened to a set torque?
A suitable machine can improve torque consistency, but the achievable result depends on the cap and bottle.
