Can Filling Machine

Filling and seaming are two separate operations. The filling machine dispenses the product into the open can; the seaming machine then closes it by forming a double seam between the can end and the can body. Many of our machines combine both in one unit, which avoids transferring open cans between stations and the oxygen pickup that comes with it. Seam quality is set by the seamer, not by the filler.

A double seam is the two-stage fold that joins the can end to the can body, and it forms the only barrier between your product and the outside air. On a single machine it is judged two ways: externally by non-destructive visual and dimensional checks, and internally by tearing down the seam and measuring the overlap between cover hook and body hook. Overlap is the critical dimension. What determines it is the seamer itself: roll and chuck condition, the timing of the first and second operation, lubrication, and can/end compatibility.

The machine runs 330 ml and 500 ml cans as standard, with can heights from 50 mm to 350 mm (customizable) and the common 202 / 204 and 211 body diameters covered by the seamer change parts. Can sizes are set by changeable format parts and seamer change parts, so one machine can run more than one can format rather than being locked to a single size. Send your can specification and target output and we will confirm the change parts required.

Yes — our Bottle & Can Filling and Capping Machine supports both container types in one system, with quick format switching. This is usually the right choice if you want to test a can SKU without buying a second machine, or if you package the same product in more than one format. If you plan to run cans at high volume continuously, a dedicated can line gives higher output.

Rinsing before filling removes dust and debris from new cans so they do not end up in the package. Can rinsing is specified as part of the canning line — the can rinsing and loading platform is quoted with the filling and sealing machine — and it can be added as an option when the filler is bought as a stand-alone machine. As your SKU count grows, an inline rinser is normally recommended over manual handling — manual handling is also an opportunity for re-contamination immediately before the fill.

At 330 ml, expect roughly 600–900 CPH at 4 heads, 900–1,400 at 6, 1,400–2,000 at 8 and 2,000–2,800 at 10 heads; still products run at the top of each band and carbonated products at the bottom, and 500 ml cans reduce the figure slightly. Output depends on can size, fill volume and the number of filling heads, and it differs between still and carbonated products because isobaric filling takes longer per can. Give us your can specification and target cans per hour and we will recommend the head count and seamer configuration that meets it.

The filling valve configuration differs between the two. Carbonated products need isobaric (counter-pressure) filling to hold CO₂ in solution and prevent foaming; still products use a simpler gravity or volumetric fill. Both can be met on one machine: the valve set is the changeable element, so the same body is fitted with isobaric valves for carbonated products and with gravity or volumetric valves for still products. Tell us your product mix and we will specify the correct valve set.

Cost depends on head count, can format, whether seaming is integrated, and whether you add rinsing, drying, coding or labelling. Because these options change the machine substantially, we quote per configuration rather than quoting a headline number. A 4-head machine and an 8-head machine with integrated seaming, rinsing and drying differ enough that a published list price would mislead more than it helps.
