Extrusion Process Rod Coater

The extrusion-type wire rod Coater uses a screw or piston to extrude the coating material, forming a uniform film through the gap of the wire rod. It is used in laboratories to simulate the coating process and test the spreading performance of coatings on substrates such as paper and plastic.
Selection
When selecting, consider that the coating width matches the sample size, the gap of the wire bar determines the wet film thickness, and the material must be corrosion-resistant. Choose between screw or piston types based on the viscosity of the coating, as ease of operation affects experimental efficiency.

This paper investigates the relationship between the wire diameter in a wire-wound rod coater and the wet film thickness. Theoretically, under ideal conditions, the wet film thickness is approximately half of the wire diameter.
Actual Coating Thickness Deviation of Stainless Steel Wire Rod Coaters at Different Slurry Solid Contents
This article analyzes the actual coating thickness deviation of stainless steel wire rod coaters under different slurry solid contents. The study finds that the solid content of the slurry affects its viscosity and flowability, leading to deviations in the actual coating thickness from the theoretical value.

A wire-wound rod coater is a laboratory tool used for preparing uniform wet film coatings on flat substrates, widely applied in the production of samples in the coatings, inks, and printing industries.
The difference between a wire bar coater and a gap-type wet film applicator.
The wire-wound drawdown bar directly quantifies the coating through the gap between wires, making it suitable for thin coating preparation with high precision, particularly for low-viscosity fluids. In contrast, the gap-type wet film applicator indirectly controls film thickness through the groove depth, with the actual coating thickness significantly influenced by material properties, making it more suitable for high-viscosity coatings and thick film preparation.
