The Vacuum Chuck Wire Bar Coater is a high-precision, multi-functional automated film preparation platform meticulously developed by Shandong Annimet Instrument Co., Ltd. based on rigorous laboratory standards and broad material application needs. By achieving precise closed-loop control over the three core parameters—coating speed, coating pressure, and substrate flatness—it elevates laboratory coating processes from experience-dependent "manual art" to quantifiable, reproducible "exact science." The instrument uses a wire bar coating method with a coating speed of 1-2000 mm/min, an effective coating size of 200×300 mm, and an imported ASP wire bar with a thickness range of 1.5-800 μm. Vacuum adsorption holds substrates such as copper foil, aluminum foil, plastic sheets, and glass that cannot lie flat by themselves. The mold steel base plate is quenched and mirror-polished to a flatness of ≤±2.5 μm. A 5-inch touchscreen with the Annimet Testing Control System V1.0 supports dead-weight or lever pressure. It is widely used for precise laboratory sample preparation of lithium battery slurries, perovskite precursors, paints, inks, and pressure-sensitive adhesives.
