Wire rod coaters (also known as metering rods, wire rods, scraping rods, glue squeegees, and sizing rods) are a widely used coating method in the domestic paper production, adhesive tape production, and various film coating industries. They utilize the tooth-shaped cavity area of the metering rod to apply a measured amount of glue to the substrate surface. Typically installed behind the coating roller of a coater, they precisely control the amount of glue removed. Different metering rod models can be selected to achieve the desired coating amount.

Extruded Wire Rod: Extruded wire rods eliminate the risk of wire loosening or breaking, are easy to clean, and can achieve ultra-thin coatings. They utilize the principle of plastic deformation to roll various mountain-shaped shapes onto the surface of the steel rod.

Traditional wire-wound wire rods: Wire is prone to loosening and breaking, leaving residue, making cleaning difficult, and incapable of ultra-thin coating. Coating is easily performed by wrapping a thin wire around the surface of the steel rod.
