A bottle capping machine — also searched as a screw capping machine, automatic capping machine, or rotary capping system — applies and torques caps onto bottles at line speed, often right after tablet counting, liquid filling, or powder filling. Chuck cappers suit lower-speed lines with precise torque control; spindle cappers handle continuous screw-cap application at higher throughput; rotary capping machines deliver the highest bottles-per-minute for production-scale packaging. SED Machines helps U.S. buyers choose the right capping style matched to cap type, bottle range, and line speed.

A screw capping machine drives threaded caps onto bottles by rotation — the most common closure style for pharmaceutical and nutraceutical plastic bottles. Within screw capping, buyers choose between chuck cappers (single-head, lower speed, precise torque per cycle) and spindle cappers (continuous friction drive, higher BPM). Rotary capping machines use multiple heads on a rotating turret to reach the highest throughput — typically 60 to 200+ bottles per minute depending on the model. Selecting the right capping machine depends on cap diameter range, required torque consistency, and bottles per minute.
SED Machines helps U.S. buyers compare chuck, spindle, and rotary capping based on actual production requirements rather than overspecifying heads or speed.
Pharmaceutical and nutraceutical packaging demands consistent applied torque to ensure seal integrity without over-tightening. Capping machines with adjustable torque clutch or servo control allow operators to set and verify torque for each cap size. Changeover between cap sizes involves adjusting chuck inserts, spindle rollers, or rotary head tooling — buyers running multiple SKUs should factor changeover time and tooling sets into their capping machine selection.
Bottle capping sits in the middle of a typical pharmaceutical packaging line: bottles are unscrambled and fed into filling (tablets, capsules, liquids, or powders), then capped, induction sealed for tamper evidence, and labeled. Each station must match on bottles per minute. SED Machines scopes capping machines alongside upstream filling and downstream sealing and labeling so the complete bottle packaging line runs at balanced throughput.
Share bottle diameter, cap type (screw, press-on, child-resistant), torque needs, and bottles per minute — we recommend chuck, spindle, or rotary capping configurations that fit the range.
Screw capping machine describes the closure style applied by rotation. Automatic capping machine describes continuous, hands-free line speed. Rotary capping is a common automatic layout for high bottles-per-minute screw caps; chuck and spindle cappers cover lower to medium speeds.
Capping applies the cap first; induction sealing then bonds the foil liner under the cap. The sequence is fill → cap → induction seal → label for a complete tamper-evident bottle line.
A chuck capper uses a single gripping head that descends onto each cap and applies torque in one cycle — precise but slower. A spindle capper uses friction wheels to spin the cap on continuously — faster and better suited for higher throughput lines.
Adjustable torque clutches or servo drives let operators set applied torque per cap size. Verify torque with a bottle torque tester during setup and include torque checks in your packaging line quality control routine.
Most capping machines support changeover between cap sizes by swapping chuck inserts, spindle roller sets, or rotary head tooling. Share your cap range and SKU count so we recommend a capper with practical changeover windows.
Yes. SED Machines scopes bottle capping machines together with tablet and capsule counters, liquid fillers, powder fillers, unscramblers, induction sealers, and labelers as integrated packaging line solutions.
Rotary capping machines typically handle 60 to 200+ bottles per minute depending on the number of heads and turret speed. Share your target BPM and cap type — we recommend rotary configurations that match your production volume.
