Sealing strips are primarily used in the manufacture of automotive and refrigerator seals, as well as other soft sealing products. This production line features a high degree of automation, simple operation, an attractive appearance, and excellent performance. Suitable materials include PVC, EVA, and other pelletized resins. The process consists of a single-screw extruder, a die, a cooling and shaping water tank, a belt‑type haul‑off unit, and a dual‑station winder. The door and window seal extruder boasts advantages such as low energy consumption, high efficiency, easy operation, and a high level of automation. During operation, users can switch dies according to their needs, enabling the production of aluminum alloy door and window seals, automotive seals, and plastic‑steel door and window seals in various shapes.
