This PVC profile machine/PVC UPVC windows profile extrusion machine is specializing in producing PVC plastic profiles including windows and doors, decorative plates,foam profile etc.By absorbing advanced technology from abroad, our company developed the large plastic profile extrusion line, which is equipped with conical double screw extruder, and it possesses the advantage of high degree automation, stable performance,high output and efficiency, etc.

1. Raw Material Preparation: The first step of the production line is to prepare the raw materials required for PVC manufacturing, including PVC powder, additives, and stabilizers. These raw materials are usually mixed in a certain proportion in the batching system.

2. Mixing and extrusion: The mixing process sends raw materials into the mixer for thorough mixing, ensuring the uniform distribution of various additives and stabilizers. Then, the mixed material is fed into the extruder, and through the process of heating and high-pressure extrusion, the material is extruded into the desired profile shape.

3. Cooling and cutting: The extruded PVC profiles enter the cooling device through conveyor belts or rollers to quickly cool and solidify. Then, the profile is cut to length by a cutting machine to obtain the required length.

4. Inspection and packaging: The final step of the production line is to conduct quality inspection and packaging of the finished product. Inspect the dimensions, appearance, mechanical properties, and other aspects of the profile to ensure that the product meets quality standards. Then, the profiles are usually packaged in a form suitable for transportation and storage.

It is worth noting that different PVC door and window profile production lines may have some differences, and the specific production line configuration and process flow may vary. In addition, some production lines may integrate automated control systems to improve production efficiency and product quality.
