An automatic chuck capper applies and tightens caps using a chuck that grips the closure during the capping process. The cap and container are positively controlled to provide accurate cap placement and consistent final torque. Chuck cappers are particularly well suited for applications where precise closure engagement, repeatable torque, or control of larger caps and containers is required.

A spindle capper is an automatic bottle capping machine that applies and tightens screw caps using multiple sets of rotating spindle wheels. It is one of the most common capping solutions for high-speed packaging lines because it can continuously cap bottles without stopping.

A chuck capper uses a chuck to individually engage and tighten each cap, providing positive control of the closure during application. A spindle capper moves containers continuously through sets of rotating wheels that progressively tighten the cap. Chuck cappers are often selected when greater control of cap placement and torque is required, while spindle cappers are commonly used for higher-speed continuous-motion applications.

Spindle cappers are ideal for high-volume production and applications where continuous operation and throughput are the priority. Chuck cappers provide more precise torque control and are often preferred for applications requiring exact torque specifications or handling specialty closures.

A chuck capper is a good choice when your application requires precise cap placement, consistent torque, positive container control, or handling of large or challenging closures. They can also help reduce problems such as cross-threading when properly configured for the container and closure.

Aesus chuck capping machines can be configured for a wide range of threaded closures and container sizes. Depending on the application and machine configuration, specialized closure requirements such as snap-on caps can also be accommodated. Each capping system is configured around the specific container, closure and production requirements.

Aesus spindle cappers can handle a wide variety of screw caps, including:

• Flat caps
• Ribbed caps
• Child-resistant caps (depending on the application)
• Some others – Contact Aesus to confirm.

Machine configuration and testing determine compatibility with specific cap designs.

Aesus spindle cappers can accommodate many container styles, including:

• Plastic bottles
• Glass bottles
• Jars
• Round containers
• Oval containers
• Square containers
• Custom-shaped containers

Optional change parts and adjustments allow the machine to handle different sizes and formats.

Contact Aesus to have your container assessed for compatibility.

Production speed depends on the machine configuration, container, closure and product. The Aesus Delta Cap 2 operates at speeds up to 40 bottles per minute, the Delta StarCap up to 50 bottles per minute, and the Premier StarCap up to 80 bottles per minute. Actual production speeds may vary depending on the application.

Depending on the model and application, Aesus spindle cappers can achieve speeds of up to 120 bottles per minute. Actual production rates depend on bottle size, cap style, product characteristics, and line configuration.

Aesus chuck cappers can be integrated with an automatic cap sorting elevator or vibratory bowl feeder. These systems sort and orient bulk caps before delivering them to the cap track and capping system, allowing continuous automated operation with minimal operator handling.

Yes. Aesus spindle cappers can be equipped with a cap sorting elevator or an optional vibratory bowl feeder to automatically orient and deliver caps to the capping machine for fully automatic operation.

A starwheel indexing system captures and accurately positions each container at the capping stations. This positive container control is particularly useful for applications requiring precise alignment of the container, cap and chuck. Aesus offers starwheel chuck cappers for applications requiring controlled indexing and higher production speeds.

Yes. Aesus chuck cappers can be integrated with bottle unscramblers, liquid or powder filling equipment, conveyors, labelers, shrink sleeving equipment and accumulation tables to create a complete automated packaging line. Controls and line integration can be configured around the requirements of the application.

Yes. Aesus spindle cappers are designed for seamless integration with existing conveyors, fillers, labelers, induction sealers, shrink labelers, and other packaging equipment.

Aesus cappers are commonly used in:

• Food and beverage
• Pharmaceutical
• Nutraceutical
• Cosmetic
• Personal care
• Household chemical
• Industrial chemical

applications requiring reliable, high-speed automatic screw cap application.

Yes. The machines are designed for quick changeovers and can be adjusted to accommodate different bottle diameters, heights, and cap sizes, making them suitable for manufacturers producing multiple SKUs.
