Sandwich panel production line from China

A sandwich panel line is either a small line gluing steel skins to EPS or wool boards, or a continuous foaming line over 100 metres long, and the fire class your customers need decides which.

Two quotes, one machine name

What hides inside the price

Core: board laminating or liquid foaming

EPS and wool lines glue boards between skins. PU and PIR lines foam liquid chemicals between them. Different machines, different price.

Roll formers for both skins

Ask whether both skin profiles are included and how long a profile change takes.

Glue or foam dosing

The glue spreader or foaming head decides bond strength. Ask its make and dosing method.

Line speed and length

Laminating listings state 1 to 4 m/min; continuous listings 3 to 7 m/min.

Buy something else if

Named, not hedged

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 · 2Two listings for EPS and rock wool laminating lines, checked October 2026, advertised US$22,500 to US$38,000, with 1 to 4 m/min speed and about 34 to 40 m line length. Asking prices, not landed cost.
Listings · 2Two continuous PU, PIR and wool line listings, checked October 2026, advertised US$1,000,000 to US$1,500,000, at 3 to 7 m/min and 100 to 118 m long.
ArithmeticUS$1,000,000 / US$38,000 = about 26, so the cheapest continuous line cost about 26 times the dearest laminating line.

Straight answers

Questions buyers ask about this machine.

Chinese vs European sandwich panel production line: which fits?+

For EPS and wool laminating, Chinese lines cover much of the market. For continuous PU, compare the foaming head, belt press and service closely.

What should a sandwich panel production line inspection checklist cover?+

Profiles against drawings, glue or foam dosing, cutter accuracy and a timed run on your materials.

What CE documentation does a sandwich panel production line need?+

A machinery declaration for the line. The panels need their own route under EN 14509.

Who is the EU importer of a sandwich panel production line?+

Usually your company, when you buy direct. Your name goes on the machine or its papers, and you check the conformity file.
