A PVC WPC profile extrusion line is used for window and door profiles, decorative profiles, WPC door frames, WPC decking profiles, edge strips and other plastic profile products. The final machine configuration should be selected according to material formula, profile shape, mould size, cooling length, haul-off force, cutting method and surface treatment requirement.
Direct answer: A practical PVC WPC profile production line normally includes material mixing, conical twin screw extrusion or single screw extrusion, profile mould, vacuum calibration table, haul-off machine, cutter and stacking table. For WPC projects, material preparation and stable cooling are especially important because wood powder content, profile size and surface finish strongly affect line speed.
The process starts from PVC, WPC or modified plastic material preparation. After mixing and feeding, the material is plasticized by the extruder and shaped by the profile mould. The hot profile then passes through vacuum calibration and cooling before it is pulled, cut and collected.
Process Step | Main Equipment | Selection Point |
|---|---|---|
Material preparation | High-speed mixer, cooling mixer and feeding system | Important for PVC formula stability and WPC wood powder dispersion. |
Extrusion | Conical twin screw extruder or single screw extruder | Choose by material type, profile size and output target. |
Profile forming | Profile extrusion mould and calibration tooling | Match product shape, wall thickness and surface requirement. |
Cooling and calibration | Vacuum calibration table and water cooling system | Controls profile dimension, straightness and surface quality. |
Traction and cutting | Haul-off machine, saw cutter or automatic cutter | Haul-off force and cutting accuracy should match profile width and hardness. |
Receiving | Stacking table or collection device | Needed for stable continuous production and easy packaging. |
PVC profile projects usually focus on window profile, door profile, corner bead, decorative strip and sealing profile. WPC profile projects often focus on door frames, wall panels, decking profiles and outdoor decorative profiles. Both use profile extrusion, but WPC processing needs more attention to formula moisture control, screw wear resistance and cooling stability.
Project Type | Typical Product | Machine Focus |
|---|---|---|
PVC profile production line | Window profile, door profile, corner bead, cable trunking, decorative strip | Profile mould accuracy, vacuum calibration and surface quality. |
WPC profile production line | WPC door frame, WPC decking, WPC wall profile, composite decorative profile | Material mixing, extrusion stability, cooling and haul-off force. |
Edge and small profile line | Edge banding, sealing strip, narrow decorative profile | Stable speed, accurate strip width and neat winding or cutting. |
Before choosing the line, confirm the profile drawing, material formula, profile weight per meter, expected output, surface treatment, cutting length and workshop layout. A line selected only by extruder model may not run well if the mould, calibration table, haul-off and cutter are not matched.
For larger WPC profile or door frame, choose stronger extrusion and downstream support.
For PVC window and door profile, focus on profile accuracy, straightness and surface finish.
For small decorative profile, edge banding or strip products, focus on stable speed and receiving method.
For high wood powder WPC material, confirm drying, mixing and screw wear resistance.
For projects with frequent product changes, confirm mould change time and calibration table adjustment.

Some equipment sections are similar, but the screw, mould, formula, cooling and haul-off should be confirmed by the main product. WPC profiles normally need more attention to material preparation and wear resistance.
Prepare the profile drawing or sample, material formula, width, thickness, weight per meter, output target, surface treatment and cutting length. These details decide the extruder, mould and downstream configuration.
The calibration table controls profile shape, straightness and cooling. If it is too short or not matched with the mould, the final profile may deform or fail dimensional requirements.
Selection note: Do not select a PVC WPC profile line only by output number. Profile shape, formula and cooling stability are often more important for real production quality.
