Used can filling machines combine an isobaric counter-pressure filler with a seamer in a single synchronised machine — the seamer applies the end (lid) to the filled can immediately after filling to prevent CO2 loss. KHS, Krones and Cermex are common on industrial can filling lines; craft canning machines are seen from Wild Goose, Codi and Meheen.
Can filling is used for beer, CSD and energy drinks across all production scales, from compact craft canning systems to high-speed industrial lines. Rated output is stated per machine and depends on can format and product.
Buying Guide — Used Can Filling Machines
The seamer is the critical quality component on a canning line — it applies the double seam that seals the can. Verify: seam dimensions (seam thickness, seam height, overlap) against can manufacturer specifications, seaming roll condition, and chuck wear. A poorly maintained seamer causes seam failures that result in product spoilage and retailer recalls.
Oxygen control matters in canning as in glass bottling; the target belongs to your own product specification. Check CO2 pre-purge capability on the can filler, and where pasteurisation is part of the process check temperature uniformity and PU control on the pasteuriser or warmer.
Frequently asked questions
What should I check before buying a used can filling machine?
Check seam quality records and seaming roll and chuck condition, the can diameters and heights the change parts cover, filler valve condition and CO2 pre-purge capability, end (lid) format, and the electrical documentation supplied with the machine.
What is a double seam?
A double seam is the hermetic seal formed when the seamer rolls the can end and can body wall together in two operations — the first operation hooks the end over the body, the second compresses and flattens the seam to create a leak-proof seal.
