Capping Machine vs. Manual Capping and the Conveyor System

Efficiency and consistency are keys to success across the entire packaging process, whether rinsing, filling, capping, or otherwise preparing a product. When deciding how to protect and seal liquids, one important decision is whether to rely on manual labor or invest in automation. Manual capping versus automatic sealing involves significant differences in speed, accuracy, and even scalability.

Manual Capping of Bottles

Startups or small businesses may begin with manual capping of bottles due to the limited production demand. The capping, or even packaging process as a whole, may not be a daily task and manual labor might share this duty with other job assignments. This will typically involve gathering the bottles, hand-placing the caps, then hand-tightening the caps. While manual capping does offer some flexibility and low upfront costs, it will also quickly show crucial limitations if demand starts to increase! And even without an increase in demand, the human interaction equals variables in torque or tightness, meaning inconsistent application. Loose caps can result in product waste through leaks or contamination, not to mention angry customers. Overtightened caps can damage bottles or closures as well. And while costs may start lower, slow production and a never-ending need for labor can become costly over time. A majority of packagers will usually outgrow manual capping and require automation to remain efficient and keep up with demand.

Bottle Capping Machines

A bottle capping machine can eliminate challenges presented above with the manual process. Whether semi-automatic or fully-automatic, capping machines are engineered to apply caps in a precise, repeatable manner, protecting product integrity regardless of the closure being applied. Automated capping machines are manufactured specifically for the closure, which can include screw caps, snap caps, ROPP closures, corks, and more. Built with easily adjustable components to allow for quick changeover from cap to cap, these machines can meet significantly higher demands while also improving the quality of the process. By reducing reliance on manual labor, they also lower the risk of human error and fatigue, making the work environment both safer and more efficient.

A Key Contributor - Stainless Steel Conveyors

While automating bottle capping machines is a step up from manually capping containers, the true potential of automation will only be realized when the bottle movement is also automated. Integrating capping machinery, and other packaging equipment, with a stainless steel conveyor system helps to minimize the need for manual labor. Conveyors act as the circulatory system, moving bottles not just through the capping machine, but from one machine to another.

While other materials are available for unique packaging environments or projects, stainless steel conveyors are valuable due to their durable construction and resistance to corrosion. In addition, stainless steel surfaces are easy to clean and sanitize, making them an ideal choice for food and beverage packagers, personal care, pharma, and other industries where hygiene is critical to the process. When integrated to create a complete packaging line, the conveyor system can also use sensors to help machines communicate with one another, allowing the machines to react to jams or misalignments and assisting in troubleshooting. The integrated conveyor system helps to create a continuous workflow that can be nearly impossible to match with manual labor.

Moving from manual to automated capping offers advantages including higher output, consistency, easy changeover and clean up, and reduced labor cost. Manual capping requires additional workers, whereas automatic capping offers the flexibility to increase demand without always increasing cost. Combining automatic packaging machinery with a stainless steel conveyor system offers even greater flexibility by significantly improving efficiency without sacrificing reliability.
