Induction sealing machine from China

An induction sealer only heats the foil liner inside your cap, so whether the seal holds depends on the liner, the cap torque and the time under the coil, and a demo on the supplier's own caps proves almost nothing about yours.

Two quotes, one machine name

What hides inside the price

Power and cooling

Air-cooled units suit lower power and slower lines. Water-cooled units run higher power for faster conveyors and larger caps, and need a chiller. Ask the power at your cap size.

Coil head shape

Flat heads cover standard caps; tunnel heads suit sports caps and deep closures. Ask which head the cap range figure used.

Conveyor speed and dwell

Speed is quoted in metres a minute, not bottles. Bottles a minute depend on your spacing, and the seal needs a minimum time under the coil.

Reject function

Better units detect a missing foil or a cap without a liner and push the bottle off. Many do not. Ask for it in writing.

Before you ask for a price.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.

The liner type: one-piece or two-piece, and heat seal layer.
Bottle material and cap torque as applied.
Bottles per minute and bottle spacing on your conveyor.

The documents that must arrive with it.

EU Declaration of Conformity with model and serial number.
EMC test report under 2014/30/EU, since the coil emits a strong field.

Where the numbers come from.

We name the kind of source, how many and when, and never the factory. Listed prices are asking prices, not landed cost. Where we do not hold a fact we say so: that is a GAP, not an estimate.

Listings · 13Thirteen induction sealer listings on one marketplace, checked September 2026, advertised asking prices from US$45 for a handheld unit to US$9,000 for an automatic machine.
Listings · 1One air-cooled automatic listing, checked September 2026, stated 20 to 130 mm caps, a conveyor speed of 0 to 12 m a minute and 1.5 kW.
ArithmeticAt 12 m a minute and bottles every 100 mm, the conveyor carries 120 bottles a minute, before any limit set by dwell time.
