Plastic profile extrusion line from China

On a profile line the die and calibrators are cut for one cross-section, so the buyer is really buying tooling, and a quote without the die for your profile has no real price yet.

What hides inside the price

Die and calibrators per profile

Each cross-section needs its own die and calibration blocks. Ask which profiles are in the price and the cost of each further set.

Extruder for the compound

Rigid PVC dry blend usually runs on a conical twin screw. Foamed WPC with wood flour needs venting and a screw built for it. Eleven of thirty listings named WPC.

Calibration table

Vacuum and cooling length set line speed. Ask the table length.

Haul-off and cutter

Ask haul-off grip, cut-length accuracy and dust extraction.

Co-extrusion and finishing

Soft seals, cap layers, foil lamination or punching need extra units. Ask which appear in the quote.

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.

Profile drawings with tolerances and wall thicknesses.
Compound: PVC, WPC or other, with filler and regrind share.
Output per profile in kilograms per hour or metres per minute.
How many profiles you will run and how often you change them.
Lamination, punching or printing after the line.

Require this	A pass looks like
Run your profile through your die in your compound to steady state for a timed hour.	Metres and kilograms per hour match the offer for that profile.
Measure the cross-section at several points on cut lengths.	Every wall and outer dimension inside your drawing tolerance.
Send samples to a laboratory for the tests your profile standard sets.	Results inside that standard, such as EN 12608-1 for PVC-U window profiles.

The documents that must arrive with it.

EU Declaration of Conformity for the complete line under 2006/42/EC, or Regulation (EU) 2023/1230 from 20 January 2027.
Standards list, including the EN 1114 series for extrusion equipment.
Die and calibrator drawings with steel grades.

The one people forget. Die ownership in writing. Without it, the design may be sold again, and you cannot have a copy made elsewhere.

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.
