BGD 218/S & BGD219/S Automatic Film Applicator Automated Precision Coating Meter System

BGD 218/S & BGD 219 Automatic Film Applicator Automated Precision Coating Meter System

1.Description:
Automatic film applicators are used to prepare uniform and traceable coatings (manual coating often lacks consistency, particularly between different operators, making sample comparisons difficult or even unreliable), offering excellent reproducibility. This is because the factors influencing coating-shear rate and the weight applied to the application tool-are precisely controlled. The instrument employs a precisely controlled wire rod or applicator that moves back and forth at a selected speed. By maintaining consistent shear rate and tool weight during coating, reproducibility is significantly enhanced.

BGD 218/S & BGD 219/S are two automatic film applicators that incorporate the most advanced technologies from international counterparts. Compared to other domestic products, they feature the following advantages:

• *Wide-range stepless speed adjustment: 5 mm/s - 500 mm/s

• *Precision linear guide rails for smoother coating

• *Ergonomically designed coating bracket for simpler and more convenient operation. Additional bracket loads can be added to accommodate flexible substrates.

• *Adjustable substrate clamps to fit different substrate sizes.

• *Customizable coating start point to adapt to varying substrate dimensions.

• *Freely adjustable coating distance.

• *Compatibility with coating rods and applicators of various shapes and sizes (total length: 240 mm).

• *High hardness and flatness (platform error <5 μm) anodized aluminum vacuum suction platform (BGD 218/S) or a specially processed high-flatness glass platform (platform error <20 μm) for easy maintenance and cleaning (BGD 219/S).

• *Detachable coating platform for effortless cleaning and replacement.

• *Optimized vacuum suction platform with highly uniform adsorption force distribution (BGD 218/S).

• *External vacuum pump eliminates vibration caused by traditional built-in vacuum pump designs during coating (BGD 218/S only).
