Process composition:
Single-screw extruder — Die — Cooling and shaping tank — Belt-type haul-off unit — Dual-station winder
Features of the PVC sealing strip extrusion machine:
1. Single-screw extruder main unit: Features an alloy screw with a high-precision hard-chrome-plated mirror finish, an intelligent temperature controller, and quiet fan‑forced air cooling. Temperature accuracy can reach ±1°C. The drive motor employs variable-frequency control, allowing adjustable screw speed for energy efficiency. Screw diameters range from φ35 to φ90, depending on production capacity and product size.
2. Molds: Our engineers possess extensive experience in mold development and can design molds based on customer‑provided dimensions or samples. All molds are manufactured using S‑136H mirror‑finish steel.
3. Cooling and Shaping Tank: Stainless steel tank with a three-dimensional adjustable rack; simple structure and easy operation.
4. Belt-type traction machine: Equipped with a PU‑foamed multi‑groove belt as the traction element, featuring a wear‑resistant surface and an effective length of 500 mm. It delivers reliable traction even under low clamping forces, ensuring continuous, stable conveyance without deforming the product. The belt is openable and closable, with height‑adjustable positioning. The main motor is driven by variable‑frequency control, enabling precise adjustment of the traction line speed from 0 to 60 m/min.
5. Dual‑Station Rewinder The dual‑station rewinder features two winding drums that operate in tandem. Its openable and closable winding drums enable quick and convenient reel changes, and the drum dimensions can be custom‑made to suit the customer’s specific application requirements.
