The Blade 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.” The unit supports multiple blade configurations, including adjustable micrometer blades, four-sided fixed-thickness blades, and slot-die blades. It offers stepless speed control from 1 to 2000 mm/min on a mold steel base plate that is quenched and mirror-polished to a flatness of ≤±2.5 μm. The adjustable blade features a digital micrometer with 0.001 mm resolution, delivering dry film uniformity ≤1.5 μm. A 5-inch touchscreen running the Annimet Testing & Control System V1.0 and the choice of dead-weight or lever-arm pressure make this an indispensable tool for precise laboratory sample preparation in lithium-ion battery, perovskite, paint, ink, and adhesive research.
