Capping Overview
An automated capping machine applies and tightens caps, lids, corks or other closures onto filled containers as they move along a production line, replacing manual capping by hand. Kelgray designs and installs capping machines for UK manufacturers running mid to high-volume production, where consistent torque and speed matter more than a single benchtop unit can deliver.
Service information
Who This Is For
Our capping systems are built for manufacturers, not small-batch or hobbyist producers looking for a single benchtop machine. You are a good fit if:
- You currently cap by hand and are seeing inconsistent tightness, leaks or slow throughput.
- You need a specific closure type applied correctly and repeatably, such as screw caps, snap caps, corks or trigger sprayers.
- You want capping to run in step with your existing or planned filling line.
- You need tamper-evident or induction-sealed closures applied reliably at volume.
What Automated Capping Involves
Kelgray’s automated capping machines apply consistent, correctly torqued closures to every container, eliminating the variability of hand tightening, whether that means caps too loose, risking leaks, or too tight, risking cracked closures or difficult opening. The result is every container capped securely and consistently, at speeds hand capping cannot match.
Our range covers screw cappers for threaded closures, snap cappers for push-fit lids, and specialist machines for corks, trigger sprayers or induction sealing, where a foil liner is heat-sealed to the container mouth for tamper evidence. Depending on your output requirements, we can supply machines with multiple capping heads to cap several containers in parallel, and each system uses torque-controlled or servo-driven capping heads to apply the correct, repeatable tightness every time.
Capping machines integrate directly with your filling equipment, so containers move from fill to cap without manual handling, and with conveyors and sensors that keep the whole line synchronised. Changeovers between cap types or container sizes are made straightforward through quick-adjust tooling, so you can switch product lines with minimal downtime.
Why Choose Kelgray for Capping?
Consistent, Correct Torque
Our cappers apply the right tightness every time, preventing both leaking under-caps and cracked or hard-to-open over-caps.
High Speed, High Yield
Automated capping vastly increases throughput compared to hand capping, and multi-head machines cap multiple containers simultaneously for higher yield.
Closure Flexibility
Whether you need screw caps, snap caps, corks, trigger sprayers or induction sealing, we supply and configure the right capping technology for your closure type.
Complete Support and Integration
We integrate the capper with your filling line and provide installation, training and maintenance to keep it running smoothly. Capping is commonly specified alongside our Filling Machines and Conveyors, for a complete fill, cap and transport line built as one coordinated system.

Our Frequently Asked Questions
Here are all of the answers to your most common questions around Capping :
We supply cappers for screw caps of all thread types, snap or push-fit caps, corks, trigger sprayers and pumps, and induction sealing equipment for tamper-evident foil liners. We can also configure machines to handle child-resistant or tamper-evident closures where required for your industry.
Yes. We size the equipment to your product range and can include quick-change tooling or automatic adjustment so the machine handles multiple container and cap sizes with minimal manual changeover time between production runs.
Automated capping is significantly more consistent than manual capping by hand, using torque-controlled or servo-driven heads to apply the same tightness every cycle, within a tight tolerance. This reduces both under-tightened caps that risk leaking and over-tightened caps that can crack or become difficult to open.
Speed depends on your specific configuration, but automated capping will significantly outpace manual methods. Many single-head machines cap several dozen containers per minute, multiplying with multi-head systems, and we design the equipment to meet your production targets based on closure type and container size.
Yes. Our capping machines can be synchronised with filling equipment, whether from Kelgray or another supplier, so containers move seamlessly from filling to capping without manual handling, with conveyor height and layout matched for smooth transfer.
We train your operators and maintenance team on operation, torque adjustment and routine upkeep, offer maintenance packages for scheduled servicing, and supply spare parts such as chucks, belts and seals, with our support team available for any issues.
