ZONESUN CAPPING SOLUTIONS
Screw Capping Machines
ZONESUN screw capping machines provide consistent torque and reliable closure for threaded bottle caps, pumps, sprayers and droppers. Choose from servo, spindle, tracking and rotary capping systems for standalone machines or automated packaging lines.
How to Choose a Screw Capping Machine
Screw capping machines tighten threaded closures onto bottles and containers with controlled torque and repeatable sealing performance. They are commonly used for flat screw caps, lotion pumps, trigger sprayers, dropper caps and other threaded closures across cosmetic, personal care, household chemical, food and pharmaceutical packaging.
The best capping system depends on your cap design, bottle size, required production speed and whether automatic cap feeding is needed. ZONESUN offers standalone screw cappers as well as machines designed for integration with filling, labeling and complete packaging lines.
Cap Feeding and Closure Compatibility
Automatic screw capping systems can be paired with cap elevators, vibratory feeders or cap unscramblers to orient and deliver closures automatically. Depending on the machine configuration, they can handle screw caps, pumps, sprayers, droppers and other threaded closures.
Screw Capping vs. Other Capping Methods
Screw capping is intended for threaded closures. Aluminum ROPP caps, press-on caps, vacuum caps and vial crimp closures use different sealing mechanisms and are better matched with dedicated capping equipment.
