Introduction to Coating Machines

Coating machines are primarily utilized for surface coating processes involving materials such as films (e.g., PVC, PE, PET) and paper (e.g., applying hot-melt adhesive to release paper). These machines function by applying a layer of specialized adhesive, coating, or ink onto a rolled substrate; after drying, the material is either cut into sheets or rewound into rolls. Coating machines also find application within the field of intelligent manufacturing equipment for new energy technologies, such as lithium-ion batteries.

The brush coater is the oldest type of coating equipment; it was originally employed in the 1850s for the production of coated wallpaper using china clay-based coatings. Its coating heads encompass various configurations, including round brush heads, blanket roll heads, and blanket sleeve heads.

This equipment features a specialized, multi-functional coating head capable of executing a diverse range of surface coating processes. Furthermore, both the unwinding and rewinding stations of the machine are equipped with full-speed automatic splicing mechanisms, and tension control is managed automatically via a closed-loop PLC system.
