A: In most cases, yes – our cappers are quite versatile or can be customized to handle your specific caps and containers. We set up the machine with the appropriate chucks or tightening wheels to fit the diameter and shape of your caps. Whether you have standard screw caps, child-resistant caps that require downward pressure and twist, spray pump tops, or press-on lids, we have solutions to apply them. We also adjust for container height and shape: the capping head height is adjustable to accommodate different bottle heights, and we can incorporate cap positioning or alignment tools if your caps need a certain orientation (for example, if a pump needs to face a specific way). During our design phase, we’ll confirm the cap sizes (diameter, thread type) and bottle sizes you use, and configure the capper accordingly.

A: Our automated cappers come with adjustable torque controls. For chuck cappers, this might be a clutch or a servo-controlled motor that can be set to a specific torque value. For spindle cappers, we adjust the application pressure and speed to achieve the desired tightness. We’ll determine the right torque settings based on your cap’s requirements – for example, ensuring a secure seal without stripping the cap’s threads or damaging the bottle. Many machines allow you to set the torque via the control panel, and they will consistently apply each cap to that setting. Some systems even have torque monitoring, so they can detect if a cap wasn’t tightened properly. In essence, once we dial in the torque, the capper will repeat that for every cap, giving you uniform results.

A: Throughput depends on the machine type and how many capping heads it has. An inline capper might handle, say, 40–60 bottles per minute in a single-head configuration, but faster models or additional heads can increase that. Rotary cappers with multiple heads can cap hundreds of containers per minute (common in beverage or high-speed production). We’ll specify a capping solution to meet your required speed. Generally, you’ll find automated cappers keep pace with (or exceed) the filling machines – so they won’t be the bottleneck in your line. You can expect a dramatic improvement over manual capping; instead of a person capping maybe a few bottles a minute, a machine can do dozens in that time effortlessly.

A: Automated capping usually includes a cap feeding system so that operators don’t have to place caps on bottles by hand. Commonly, we use a vibratory bowl feeder or an elevator hopper that takes a bulk supply of caps and orients them correctly. The feeder then delivers caps via a chute to the capping machine’s cap placement mechanism. We will include the appropriate cap feeding mechanism as part of the solution, so your only task is to occasionally refill the cap hopper – the system does the rest automatically.

A: Yes, our capping machines are built with changeovers in mind. Typically, you might have to swap out some change parts – for instance, a chuck insert that matches a different cap diameter, or adjust the cap delivery chute for a different height. We design these parts to be as quick-release as possible (tool-less clamps or quick-change fixtures) to minimize downtime. Many cappers have scales or pointers that help you quickly move adjustments (like capper head height or guide rail width) to preset positions for each product. We can also save settings in the machine’s control system (for example, different torque or speed for different caps) so that you can recall them easily when switching products. With proper training and a bit of practice, your team should be able to perform product changeovers in a short time, keeping your line flexible.

A: We stand behind our capping systems with full support. After installation, we train your staff on operation and routine maintenance – such as cleaning capper chucks, checking belt wear on spindle cappers, or lubricating moving parts on schedule. Capping machines are mechanical, so periodic maintenance is important: replacing worn capping disks or grippers, ensuring cap feeders are clean and functioning, etc. Kelgray offers maintenance service plans where our technicians visit at intervals to service and calibrate your capper to keep it running at peak performance. We also provide spare parts for the wear components (like clamps, belts, seals) so you have minimal downtime if something needs replacement. And any time you have a question or issue, our support team is ready to assist – whether remotely or on-site if needed. Our aim is to ensure your capping operation remains smooth and reliable long-term.
