Ferrum high-speed can sealer with hygienic design and quick change

In industrial beverage filling, the final step determines the quality and stability of the product. The can closure is not only a mechanical seal, but also a safety-relevant process that must function reproducibly at high speeds.

This is precisely where a new high-speed can sealer comes in, designed for maximum precision, hygienic design and significantly reduced changeover times. The machine was developed for filling lines where product diversity, efficiency and cleanability are equally important.

High-speed can sealer as an industrial benchmark

The can sealer shown here belongs to the high-speed class and is designed for lines that continuously process large quantities. The machine takes the cans directly from the filler and guides them in a controlled manner into the sealing process. Precise guidance plays a central role here, as even minimal deviations at high speeds can lead to quality losses. The infeed table has been deliberately redesigned. Instead of a classic metal chain, a belt drive is used. This solution is more compact, reduces open surfaces and makes cleaning much easier. At the same time, the belt remains dimensionally stable and does not change length, which enables very precise positioning of the cans.

Hygienic machine design for sensitive product areas

A key development goal for this system was hygienic design. The machine is designed to hygiene class 4, making it suitable for demanding applications in the beverage industry. The entire product area is enclosed, and unnecessary surfaces have been consistently avoided. Sloping floors ensure that water drains away in a controlled manner and no residues can accumulate. The surface quality is RA 0.8, meeting high cleanability requirements. Hygienic screws, external O-rings and clearly defined sealing areas support reproducible cleaning. In addition, integrated foam cleaning is provided, allowing the product chamber to be cleaned automatically.

Servo technology as the basis for precision and flexibility

All axes of the machine are servo-driven. This consistent servo technology enables movements to be controlled precisely and repeated accurately. The advantage is particularly evident when changing formats: settings are recipe-based and do not require manual readjustment. This allows different can formats to be processed quickly and reliably. The folding curves are also fully automatic. The first and second folding operations can be set, swivelled out or fine-tuned separately. Even the panel height at the outfeed can be adjusted to compensate for tolerances in the system. These adjustment options increase process reliability, especially when changing can and lid variants.

Significantly reduced changeover times in line operation

In modern filling operations, flexibility is an economic factor. Short downtimes during product or format changes are crucial. The new can sealer reduces these times noticeably. Changing the can format is possible in a short time, and the combined change of can and lid is also significantly faster than with previous models. Compared to previous generations, changeover times have been reduced by more than half. This makes the machine particularly suitable for operations with frequent product changes or smaller batch sizes, without compromising the efficiency of the entire line.

Technical features at a glance

The combination of mechanics, servo technology, quick changeover and hygienic design results in a number of practical advantages:

• Compact infeed table with belt drive instead of metal chain
• Enclosed product chamber with sloping floors for controlled water drainage
• Hygiene class 4 with RA 0.8 surface quality
• Fully servo-driven axes for precise adjustments
• Recipe-based format and folding settings
• Significantly reduced changeover times for can and lid changes

Global service depth as an operational factor

In addition to machine technology, the availability of service plays a decisive role. Locations spread across the globe and a dense network of service technicians ensure that support is quickly available. Especially with high-speed machines, which often run in three shifts, this security is a relevant part of the overall concept.

Positioning of the manufacturer in the market

The development of such high-performance machines is closely linked to the manufacturer's experience. Ferrum Packaging AG has been active in mechanical engineering for more than a century and has established a leading position, particularly in the field of can seaming machines. The family-run company manufactures in Switzerland and is represented globally with other companies. In addition to seaming machines, the portfolio also includes centrifuges. The company is considered the global market leader in the high-speed segment. This position is reflected in the consistent further development of existing technologies, as can be seen in the can sealer described here.

Significance for modern filling lines

The can sealer presented here should be understood less as a stand-alone machine and more as an integral part of modern filling lines. Hygienic design, quick changeovers and precise servo technology address precisely the requirements that beverage manufacturers place on their equipment today. Increasing product diversity, shorter production cycles and high quality requirements can only be met with machines that take these factors into account from the outset. This shows that high speed and hygiene do not have to be a contradiction. Rather, intelligent design creates a system that combines efficiency, cleanliness and flexibility, thus redefining the industrial standard in can sealing.
