Rod coating machines precisely control coating thickness using metering rods (made of stainless steel rods wound with wires of varying diameters), achieving uniform coating of the substrate surface. Their equipment types and structures are as follows:

1. Metering Wire-Rod Coating System:

Structural Composition: Includes a wetting station, metering rods, a roll tension control system, and an automatic release function.

Working Principle: After the substrate is coated with excess liquid at the wetting station, the metering rod removes the excess liquid, forming a uniform coating. The automatic release function prevents liquid solidification and facilitates equipment maintenance.

2. Wire-Rod Coating Machine:

Structural Features: Employs imported steel rod transmission, a CNC panel, and a digital display fine-tuning device, supporting dual-mode switching between wire-rod and doctor blade coatings.

Functional Advantages: Dual-purpose machine to meet different coating needs; constructed entirely of 304 stainless steel, corrosion-resistant and rust-proof; supports upgraded functions such as drying and vacuum coating.

3. Laboratory-Grade Equipment:

Application Scenarios: New material research and development in universities and research institutes, such as research on the film-forming properties of graphene and nanomaterials.

Technical features: Supports various coating processes such as slot extrusion and doctor blade coating, and provides comprehensive technical support from equipment to process parameters.
