1. WPC composite profile extrusion line uses specially designed screw and controlling system ensure excellent plasticization and stable extruding.
2. This WPC composite profile extrusion machine is mainly used in producing of WPC (PE/PP/PVC WPC ) floor, WPC wall panel, WPC fence, WPC profiles,etc.
3. Chaging the moulds,this WPC profile extrusion machine can manufacture many different kinds of profiles according to your requrest.
4. The wood plastic composite(WPC) profile functions as the same as natural wood, but with better performance. Resistant to water,corrosion and mildew.Ideal for applications in high moisture environments.

The wood plastic composite(WPC) profile has the both features of wood and plastic so it has the appearance of natural wood and can be sawed, nailed, sticked and printed. General speaking, the rigidity of the wood plastic composite material is 2~8 times higher than the unprocessed wood and abrasive resistance 4~5 times higher even higher than marble.

What materials can be processed on WPC profile extrusion line?
The WPC profile extrusion line is designed to process a mix of wood fiber (sawdust, rice husk, or bamboo powder) and plastics (typically PE, PP, or PVC), along with chemical additives like coupling agents and lubricants.
What is the difference between single-screw and twin-screw extruder for WPC?
Conical twin-screw extruder is the industry standard for WPC. They provide superior mixing, higher torque, and better venting for the moisture inherent in wood fibers compared to single-screw models.
Can I produce different profiles on the same machine?
Yes. By simply changing the extrusion die and calibration sleeve, you can produce decking, wall panels, fencing, or door frames on the same base extruder.
How is the surface of the WPC profile finished?
WPC profiles are usually processed “off-line” after extrusion using Sanding Machines (for a wood-like grip), Brushing Machines (for texture), or Embossing Machines (for 3D grain patterns).
Why is WPC profile warping or bending?
Warping is usually caused by uneven cooling in the vacuum table or the haul-off speed not being synchronized with the extrusion speed.
Is an auxiliary mixing system necessary?
Absolutely. You need a Hot/Cold Mixing Unit to pre-mix the PVC, wood powder, and additives to ensure a homogeneous blend before it enters the extruder.
How do I choose the right plastic extrusion line for my business?
The choice depends on your specific needs, including the type of plastic you will process, the desired final product, required production capacity (throughput), and your budget. A good manufacturer will offer consultation to help you choose the right machine and plastic extrusion line configuration.
How much does plastic extrusion line cost?
The cost can vary significantly depending on the machine’s size, type (single vs. twin screw), production capacity, level of automation, and the inclusion of downstream equipment. It’s important to consider the total cost of ownership, including energy consumption, maintenance, and spare parts.
How do you handle shipping, installation, and commissioning?
We will outline the process for delivery, installation at the customer’s facility, and commissioning to ensure the machine is set up and running correctly.
