The Wire Bar Coater is a high-precision, multi-functional automated film preparation platform meticulously developed by Shandong Annimet Instrument Co., Ltd. to meet rigorous laboratory standards and broad material application requirements. By achieving precise closed-loop control over the three core parameters—coating speed, coating pressure, and substrate flatness—it elevates the laboratory coating process from an experience-dependent “manual art” to a quantifiable and reproducible “exact science.” Driven by a high-performance motor with stepless speed control from 1 to 2000 mm/min, it utilizes imported ASP wire bars to achieve a coating thickness range of 1.5 to 800 μm over an effective area of 200 × 300 mm. The mold steel base plate is hardened and mirror-polished to a flatness of ≤±2.5 μm, ensuring exceptional coating uniformity. A 5-inch touchscreen provides intuitive control, and the unit supports both dead-weight and lever-arm pressure application. It is ideal for preparing films of battery electrode slurries, perovskite precursors, paints, inks, and pressure-sensitive adhesives, serving as an indispensable reliable tool for R&D and QC.
