SED-8000SCGF-J automatic plastic-cup form-fill-seal (FFS) machine for 150–200 g fills at ±1.5 g accuracy, with 8-cup linkage configuration producing 5000–8000 cups/h. Process route: PS sheet preheat → vacuum/compressed-a
Funcionamiento
PS sheet is advanced by a servo motor and chain-clamp traction mechanism. In the preheat zone, alloy-aluminum preheat plates with PID temperature compensation uniformly heat the sheet. A punch with filtered compressed air then blow-forms the sheet into cup cavities in the mold, followed by water cooling. A volumetric servo-driven external filling system dispenses a metered dose (150–200 g). The top film is heated and punched to form wedge-shaped openings; pneumatic heat-seal heads with Teflon-coated contact surfaces seal at controlled temperature and pressure. A combined die performs simultaneous punch-cut and die-cut, ejecting waste synchronously.
