Plastic Profile Production Line

The Plastic Profile Production Line is a versatile manufacturing system used to produce a wide range of plastic profiles for various industries.
Professional Parameters: This line typically includes a conical twin-screw extruder, vacuum calibration table, haul-off machine, cutting machine, and stacking system. The extruder is designed to handle PVC materials efficiently, with a degassing system to ensure excellent plasticization. The mold and calibrator are made from wear-resistant materials to maintain precise dimensions.
Application Scenarios: Ideal for building construction, interior decoration, and cable management systems. PVC profiles are also used in agricultural settings for greenhouse structures and irrigation systems.
2. WPC (Wood-Plastic Composite) Profile Production Line
Professional Parameters: This line includes a conical twin-screw extruder, vacuum forming table, haul-off machine, cutting machine, and stacking system. The extruder is designed to handle the unique properties of WPC materials, which combine wood fibers and plastic. The production line can produce profiles with a wide range of dimensions and shapes.
Application Scenarios: Widely used in outdoor construction, landscaping, and furniture manufacturing. WPC profiles are also used in the automotive industry for interior trim and other applications.
3. PS (Polystyrene) Foaming Profile Production Line
Professional Parameters: This line includes a single or twin-screw extruder, vacuum forming table, haul-off machine, cutting machine, and stacking system. The extruder is designed to handle PS materials, which are processed with foaming agents to create lightweight and insulating profiles. The production line can produce profiles with a wide range of dimensions and shapes.
Application Scenarios: Ideal for interior decoration, KTVs, hotels, and other leisure facilities. PS foaming profiles are also used in home decoration, halls, and meeting rooms.
These production lines are essential in the plastic manufacturing industry, providing efficient and high-quality solutions for producing a wide range of plastic profiles. They are designed to meet the diverse needs of various industries, ensuring that the final products are both functional and aesthetically pleasing.
