The production line consists of a single-screw extruder, vacuum calibration table, haul-off unit, automatic cutter, material rack, and more. By equipping different molds, it can produce various plastic profiles, including window and door profiles, container sealing strips, sheets, rods, ceiling panels, and other products. This process features a simple workflow, high output, stable quality, and low cost. Classification and Overview of Plastic Profiles: Plastic profiles refer to extruded plastic products with non-circular cross-sections—any shape other than round, square, or flat, such as corrugated, grooved, T-shaped, etc. These profiles are typically made mainly from plastics, sometimes incorporating metal components, and are widely utilized in construction, interior decoration, and related industries. There are two main types of plastic profiles: all-plastic profiles and composite profiles, which combine plastic materials with non-plastic materials. 1. Based on the hardness of the profile, they can be categorized into soft profiles and rigid profiles. According to the type of plastic used, they include PVC profiles, ABS profiles, PE profiles, and others, with PVC profiles being the most common. 2. Classified by cross-sectional characteristics, plastic profiles can be divided into seven major categories: hollow tubes, hollow profiles, plug-type profiles, open-profiles, segmented profiles, inlaid profiles, and solid profiles.

Applications and Features:

The single-screw plastic profile extrusion line is primarily used for processing PVC, PC, PE, and other plastic profiles. The production line comprises a single-screw extruder, a vacuum calibration table, a haul-off unit, an automatic cutter, a material rack, and other components. By equipping it with different dies, it can produce a wide range of plastic profiles, including window and door profiles, container sealing strips, sheets, rods, ceiling panels, and more. The process features a simple workflow, high output, stable quality, and low production costs.

Classification and Overview of Plastic Profile Products:

Plastic profiles are extruded plastic products with non-circular cross-sections; they include shapes other than round, square, or flat, such as corrugated, channel, and T‑shaped sections. Plastic profiles are primarily made of plastic—sometimes reinforced with metal sheets—and are widely used in construction, interior decoration, and related industries.

There are two types of plastic profiles: one is all-plastic profiles, and the other is composite profiles made by combining plastic materials with non-plastic materials.

1. Based on the softness or hardness of plastic profiles, they can be classified into flexible profiles and rigid profiles. By type of plastic, they include PVC profiles, ABS profiles, PE profiles, and others; among these, PVC profiles account for the majority.

2. Based on the cross-sectional characteristics of plastic profiles, they can be classified into seven major categories: profiled tubes, hollow profiles, plug‑type profiles, open‑section profiles, sectional profiles, inlaid profiles, and solid profiles.
