Wound type line Rod

Wound wire bars are formed by tightly winding stainless steel wire around a metal rod to create grooves. The transfer volume of the coating is controlled by the groove capacity. They are used for uniformly applying liquid samples onto substrate surfaces in laboratories or production lines and are suitable for quality control and thickness testing in industries such as inks and coatings.
Selection
The selection of a wire-wound applicator should match the required wet film thickness, with the wire diameter specification determined based on sample viscosity, and the rod length chosen according to the substrate width. Stainless steel material is suitable for most chemical environments, while the uniformity of the grooves affects the coating performance. Timely cleaning and maintenance after use can help maintain precision.

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.
