The metering rods for HM coating machines are manufactured using precision molds and cold-pressing technology to create raised and recessed wavy lines on the surface of the steel rods, resulting in rods with grooves of various shapes. The smooth, flowing curves on the surface make cleaning very easy. These grooves enable precise control of wet film thickness. Since the rod does not break, cleaning is also easier. It delivers accurate and repeatable surface coating for most substrates. Most notably, it overcomes the limitations of traditional wire rod applicators by achieving a wet film thickness as low as 1.5 μm, thereby solving the challenge of ultra-thin film coating.

Metering rods are primarily used for flow control. Our company also offers smooth rods designed to control the rheology of liquids. These smooth rods have a smooth, embossing-free surface, similar to stainless steel rods, and undergo special surface treatment. Coating with smooth rods relies primarily on the adsorption or penetration of the coating into the substrate to ensure uniform distribution across the substrate’s surface.
