PVC/WPC Profile Extrusion Line



PVC profile extrusion line is a type of production line used to manufacture windows and door profiles. This line consists of several components, including an extruder, a calibration table, a haul-off machine, a cutting machine, and a stacker.

The function of the PVC plastic window frame extrusion line is to melt and shape PVC resin into the desired window frame profile. The extruder heats and melts the PVC resin, which is then forced through a die to create the shape of the window frame. The calibration table helps to cool and solidify the PVC profile, while the haul-off machine pulls the profile through the line at a consistent speed. The cutting machine then cuts the profile to the desired length, and the stacker collects and stacks the finished window frames.


PVC plastic profile extruder is a machine used for PVC profiles extrusion, such as window frames, door frames, and other custom special shapes.

The extruder works by feeding raw PVC material into a hopper, where it is heated and melted. The molten PVC is then forced through a die, which shapes the material into the desired profile.

PVC plastic profile extruders are commonly used in the construction industry for the production of building materials. They offer high efficiency and precision in the manufacturing process, allowing for consistent and high-quality profiles to be produced.


The calibration table is used to ensure that the PVC profiles are accurately shaped and sized according to the desired specifications.

During the calibration process, the PVC profiles are pulled through the calibration table while being held in the desired shape by vacuum pressure. The profiles are then cooled using water to set their final dimensions and ensure that they maintain their shape once they are removed from the table.


The haul-off machine is responsible for pulling and guiding the extruded PVC profiles through the production line at a controlled speed and tension.

The haul-off machine typically consists of a series of caterpillar tracks or belts that grip the PVC profiles and pull them through the production line. The speed and tension of the tracks or belts can be adjusted to accommodate different profile shapes and sizes, ensuring that the profiles are pulled through the line at the appropriate rate.


The function of the PVC profile lift cutting machine is to accurately and efficiently cut the extruded profiles to the required dimensions. It typically consists of a cutting unit that moves along with the extruded profiles and performs the cutting operation at the specified intervals. The cutting process is often controlled by a computerized system to ensure precision and consistency in the length of the cut profiles.


The PVC profile stacker is used to collect and stack the cut PVC profiles as they come out of the cutting machine. The stacker is designed to handle the profiles gently to prevent any damage and to ensure that they are neatly and securely stacked for further processing or packaging.
