The PU-20F Full-auto Casting Machine is a high-precision engineering solution specifically designed for the automated casting of polyurethane (PU) seal packs in filter element production. In the demanding environment of filtration manufacturing, the seal's integrity is the primary determinant of leak-resistance and overall product durability. The PU-20F eliminates manual variability by integrating an intelligent dosing system with a programmable control interface, ensuring a perfect, uniform seal for automotive air, oil, and industrial filters.
Engineered for high-volume industrial lines, this machine optimizes the entire polyurethane application process—from constant temperature preservation and precise mixing to pneumatic nozzle switching and automated workbench positioning. By combining robust structural design with an X-Y axial revolving table, the PU-20F supports a diverse range of seal shapes, including round, square, and customized figures, allowing manufacturers to scale production while maintaining stringent quality standards and reducing operational overhead.
