Product Description

PVC/WPC Profile Production Line

The PVC/WPC profile production line is a complete extrusion system specially developed for producing PVC and wood-plastic (WPC) profiles in a wide range of shapes and sizes. Built around a conical twin-screw extruder, the line is capable of processing PVC and WPC raw materials directly from dry-blended powder, delivering stable plasticizing, reliable output and excellent product quality.

The production line is mainly used to produce PVC profiles such as ceiling panels, decking, flooring, cornices, planks/boards, window profiles, door frames and door boards, as well as WPC profiles for outdoor and indoor applications.

One outstanding advantage of this line is flexibility: by simply changing the mould, the same production line can produce many kinds of different profiles, which greatly improves the return on investment for profile manufacturers.

Specification

The complete production line consists of a conical twin-screw extruder and a set of downstream auxiliary equipment working in sequence:

Mixing unit - prepares and homogenizes PVC/WPC dry blends before extrusion.
Conical twin-screw extruder - plasticizes and conveys the compound under stable temperature and pressure control.
Mould (die) system - shapes the melt into the required profile section; moulds are changeable for different products.
Vacuum calibration table - sizes and cools the extruded profile precisely to maintain dimensional stability.
Haul-off machine - pulls the profile at a constant, adjustable speed.
Cutter - cuts the profile to the required length automatically.
Stacker / receiving table - collects and stacks finished profiles for convenient handling.
The conical twin-screw design is particularly suitable for PVC and WPC materials because it provides gentle, low-shear plasticizing with effective venting, which is essential for heat-sensitive formulations. The line is available in configurations from YF180 to YF1000, covering maximum board widths from 180 mm up to 1000 mm to match different production targets.

Key Configurations

Conical twin-screw extruder with precise temperature control and vacuum venting, capable of processing PVC and WPC raw materials.
Mould system designed to customer profile drawings; quick-change mould design enables multi-product production on one line.
Vacuum calibration table for accurate profile dimensioning and cooling.
Haul-off machine with variable speed drive for stable line synchronization.
Automatic cutter with adjustable cutting length and counting function.
Stacker/receiving frame for finished profile collection.
Central control panel for synchronized operation of the whole line.
Options available on request:

Automatic dosing and feeding systems.
Co-extrusion unit for multi-layer or dual-color profiles.
Additional moulds for new profile designs.
Printing, embossing or film-laminating devices for surface finishing.
Automatic stacking systems and customized voltage/frequency standards for destination markets.

FAQ

Q1: What products can this production line make?

The line is mainly used to produce PVC profiles such as ceiling panels, wall panels, decking, flooring, cornice, planks/boards, window profiles, door frames and door boards, as well as WPC profiles. Changing the mould allows many different profile shapes to be produced on the same line.

Q2: Why use a conical twin-screw extruder for PVC/WPC?

The conical twin-screw extruder provides gentle, low-shear plasticizing with good venting, which is ideal for heat-sensitive PVC and for wood-flour-filled WPC compounds. It offers stable output, uniform melt quality and reliable long-term operation.

Q3: Can one line produce several kinds of profiles?

Yes. The main machine and downstream units remain the same; only the mould needs to be changed to produce a different profile shape. Customers can order additional moulds to expand their product range at low cost.

Q4: How do I choose the right model (YF180 to YF1000)?

Model selection is based mainly on the maximum width of the profile/board you plan to produce. Please send us your product drawings and target output, and we will recommend the most suitable configuration.

Q5: Can the line process WPC (wood-plastic composite) materials?

Yes. The conical twin-screw extruder is designed to process both PVC and WPC raw materials, making the line suitable for wood-plastic decking, railing and outdoor profile production.

Q6: What are the MOQ and delivery time?

MOQ is one complete line. Delivery time depends on the configuration and mould design; please contact us for an exact schedule based on your requirements.

Q7: Do you provide mould design and custom profile support?

Yes. We can design moulds according to your profile drawings or samples, and provide complete technical support from product development to trial production.

Q8: Do you support customized voltage and automation?

Yes. We can supply machines with customized voltage and frequency standards, and automatic feeding, stacking or co-extrusion units can be added for higher automation levels.
