Choosing an induction sealer for bottle caps means balancing cap diameter, line speed, and how much you want to spend. The four listings in this capping, sealing, and closing range go from $597.56 to $3,288.00. One is a conveyor-style machine with a faster rated speed; the other three are 1800W sealers built around a 20-100mm cap range.
Quick take
The TECHTONGDA Automatic Induction Sealing Machine with Conveyor for Aluminum Foil Gaskets 220V is the only listing rated at 80-300 bottles/min, but it is also the highest-priced. The other three are 1800W sealers. Two carry the OCASAMI name in their titles, and one is the lowest-priced listing in the group.

Decision matrix
- Higher-speed line sealing: TECHTONGDA's conveyor model is the one to weigh if you need 80-300 bottles/min and have 220V power available.
- Lowest listed price: the 20-100mm Bottle Cap Automatic Sealer is the least expensive of the four.
- OCASAMI title at the lower price: the $626.02 listing is cheaper than the $628.75 listing with the same title and similar specifications.
- OCASAMI title at the higher price: the $628.75 listing matches the $626.02 version in title and key specs, so it mainly differs on price.
Product notes
TECHTONGDA Automatic Induction Sealing Machine with Conveyor

This TECHTONGDA listing is the top of the price group at $3,288.00. It uses non-contact electromagnetic induction heating for aluminum foil gaskets on plastic or glass bottles, and it is rated at 80-300 bottles/min, well above the 10-30 pcs/min on the 20-100mm sealer. The conveyor is part of the machine, and the bottle height adjustment range is 20-400mm. The trade-off is the sealing diameter of 20-60mm, which is narrower than on the other three, and the input power is 220V single-phase 2.3KW rather than 110V. It makes sense when you need integrated transport and high throughput rather than the lowest upfront cost.
1800W Bottle Cap Automatic Sealer

This is the least expensive listing in the group at $597.56. It is an 1800W continuous induction sealer with a 304 stainless-steel housing and an air-cooled cooling mode. The conveyor table measures 135*49*10cm, and the sealer includes three pure copper induction coils plus an adjustable lifting handwheel and guide rail for bottles of different heights. It is rated at 10-30 pcs/min, which is far slower than the TECHTONGDA machine's 80-300 bottles/min, so it fits better as a lower-speed, broad-diameter option. The conveyor belt can carry up to 15kg/33lbs.
OCASAMI 1800W Continuous Induction Sealing Machine (USD 628.75)

At $628.75, this OCASAMI listing sits close to the other OCASAMI entry. It has 1800W power, 110V voltage, and a 304 stainless-steel body, matching the $626.02 version. A pure copper motor drives the conveyor belt, and the controls include a real-time current and voltage display plus a speed adjustment knob. Along with the identical title, the two OCASAMI listings list the same sealing diameter and power level. The practical issue is that this is the higher-priced of the two even though the title and key specifications are identical. The price difference is $2.73, so the $626.02 listing offers the same stated specs at a lower listed price.
OCASAMI 1800W Continuous Induction Sealing Machine (USD 626.02)

Listed at $626.02, this is the lower-priced OCASAMI version of the same title. It has the same 1800W power, 110V voltage, and 304 stainless-steel body as the $628.75 OCASAMI listing, plus the same pure copper conveyor motor. If you are comparing OCASAMI units, this one is the cheaper listing and the stronger price point. Its limitation is against the lowest-priced entry: it costs $28.46 more than the 1800W Bottle Cap Automatic Sealer at $597.56, which also lists 1800W power and the same cap range. The specifications remain the same, so the $28.46 price difference is not tied to a spec change in the listing.
Final recommendation by use case
If your line needs the higher-speed conveyor model, the TECHTONGDA listing is the matchup for 20-60mm caps and 220V power. If you want the lowest listed price among the three 1800W sealers, the $597.56 Bottle Cap Automatic Sealer is the pick. If you prefer the OCASAMI title, the $626.02 listing is the lower-priced way to get it.
