Product Introduction 
The blade coater operates on the flatbed knife-over-roll principle. A precision blade forms a defined gap above the substrate, and as the blade moves linearly, it meters the fluid and spreads it into a uniform wet film. The high-performance motor, dual-rail ball-screw drive, and rigid 304 stainless steel frame guarantee linear motion and speed stability. Users can configure the instrument with a four-sided blade for quick thickness switching or an adjustable blade for micrometer-scale gap setting. The 5-inch touchscreen provides intuitive parameter control, while the quantifiable pressure system ensures batch-to-batch reproducibility, transforming manual skill into a standardized digital workflow.

Key Features 
Precision Linear Drive High-performance motor delivers stepless speed from 1 to 2000 mm/min (standard) or 1 to 200 mm/s (high-speed), with speed stability error <1%, perfectly simulating diverse production conditions.
Quantifiable Pressure Control Dead-weight or lever-arm pressure system enables digital setting and precise feedback, completely eliminating batch variations caused by manual “hand-feel”.
Ultra-Flat Reference Surface Mold steel base plate undergoes quenching and mirror-polishing to achieve flatness ≤±2.5 μm, providing the ultimate foundation for defect-free uniform coatings.
Precision Adjustable Blade Digital micrometer adjustment with 0.001 mm resolution, thickness range 0-10 mm, blade straightness ±0.0025 mm over 300 mm, dry film uniformity ≤1.5 μm.
Multiple Blade Configurations Supports four-sided blades (fixed thickness sets), adjustable blades, and slot-die blades to accommodate different slurry viscosities and coating thickness requirements.
Imported Stainless Steel Blades All blades are made from imported stainless steel with high hardness, wear resistance, and corrosion resistance, ensuring long-term precision and ease of cleaning.
Intelligent Touchscreen Control A 5-inch HMI running the Annimet control system allows intuitive setting of coating speed, stroke length, and operational parameters.
Broad Material Compatibility Mechanical clips and non-woven fabric clamps securely hold aluminum foil, copper foil, PET films, separators, and other flexible substrates for battery, paint, adhesive, and nanomaterial applications.

FAQ 
1. What are the advantages of blade coating compared to wire bar coating?
Blade coating handles a wider viscosity range, particularly medium to high-viscosity slurries and thicker wet films. The adjustable blade offers micrometer-level thickness setting, while the four-sided blade enables rapid switching among fixed thicknesses. Wire bar coating is more suited for rapid sampling of low-viscosity fluids.

2. How do I choose between the adjustable blade and the four-sided blade?
The adjustable blade is ideal for research requiring flexible setting of many different thicknesses, with 0.001 mm adjustment precision. The four-sided blade offers four fixed thicknesses on one bar for quick switching of commonly used gauges. For maximum flexibility, both can be selected as a combination.

3. What does the dry film uniformity specification ≤1.5 μm mean?
It indicates that under standard test conditions (optimized slurry viscosity, particle size, etc.), the thickness deviation of the dried film within the effective area is controlled within this range. This result is a combined outcome of machine precision, slurry rheology, and operational parameters.

4. Can the base plate material be customized?

The standard mold steel plate, quenched and mirror-polished, offers the highest flatness for most applications. For special requirements such as optical transparency or specific surface chemistry, glass, aluminum alloy, or marble plates are available as custom options.

5. How should I select the coating speed range?
The standard version (1-2000 mm/min) covers a broad range for most laboratory research. The high-speed version, reaching 1-200 mm/s (12,000 mm/min), is designed to simulate high-speed industrial processes like gravure or flexo coating.

6. How are worn blades replaced, and is recalibration needed?
Both adjustable and four-sided blades are designed for easy replacement. After replacement, it is recommended to check blade straightness and verify the gap setting with a standard feeler gauge. Original spare blades are always available from Shandong Annimet.
