When you're setting up a capping sealing closing station, the first question isn't power-both of these machines are 1800W continuous induction sealers. The real question is the size of the caps you run. One unit is built for larger bottles and wide-mouth containers, while the other is tuned for smaller narrow-mouth bottles. The choice comes down to which diameter range fits your production.
Quick Verdict
If your line mixes bottle sizes and needs one machine for everything from medium bottles to large jars, the wider-range model is the flexible pick. If your work is almost entirely small to medium bottles, the OCASAMI model with the tighter minimum diameter matches that job with a clearly stated accessory kit.
At a Glance
| Product | Listed Price | Price Bar | Cap Diameter | Shared 1800W Specs |
|---|---|---|---|---|
| 30-300mm Bottle Cap Automatic Sealer | USD 585.33 | 30-300mm | 304 stainless steel, air-cooled, 10-30 pcs/min | |
| 1800W Continuous Induction Sealing Machine (20-100mm) | USD 628.75 | 20-100mm | 304 stainless steel, air-cooled, 10-30 pcs/min |
Where the 30-300mm Sealer Wins
With the wider cap diameter range of the two, this sealer covers wide-mouth jars, large jugs, and bigger containers that the other machine's narrower range can't reach. Three pure copper induction coils support even sealing, and an adjustable lifting handwheel plus adjustable guide rail make switching between bottle sizes straightforward. If you frequently change bottle shapes, the adjustable guide rail is a practical advantage.
Where the 20-100mm Sealer Wins
If your bottles are narrow or medium, this OCASAMI machine has the tighter minimum diameter of the two, so it reaches smaller caps that the wider-range unit doesn't list. It's also the only one with a specified brand name, and the included items are clearly stated: induction bottle cap sealer, power cable, extension table, and lifting column. It runs on 110V with a US-standard plug.
Product Notes
#### 30-300mm Bottle Cap Automatic Sealer

The 30-300mm range is the standout reason to pick this machine. Wide-mouth jars and larger containers are comfortably within its stated reach, and the three pure copper induction coils plus adjustable guide rail make it suited to lines that change bottle sizes during a shift. With a conveyor table of 135 x 49 x 10 cm and an adjustable lifting handwheel, you can set the head height to match the bottles you're running. The main limitation is the small end: caps under 30mm aren't listed as supported, so very narrow bottles would be outside its range. If your production stays above that size, the wider range is the clear benefit.
#### OCASAMI 20-100mm Induction Sealing Machine

This OCASAMI sealer is the one to choose if your production is built around small to medium bottles. The 20-100mm range starts tighter than the other machine's 30mm minimum, so narrow-mouth bottles are inside its stated reach. The brand name is specified, and the included items are clearly stated: induction bottle cap sealer, power cable, extension table, and lifting column. It's rated at 110V with a US-standard plug. The trade-off is the upper limit-a 100mm cap is the ceiling-so wider caps need the other machine. For bottles that fit inside its range, this unit covers the everyday capping sealing closing work with a clearly defined set of included parts.
Final Choice by Use Case
For a general-purpose line that needs to seal everything from medium bottles up to large containers, go with the wider-range sealer at USD 585.33.
For a line focused on small to medium bottles, and where you want a branded unit with a clearly stated accessory package, pick the OCASAMI sealer at USD 628.75.
