The roll -to -roll slit extrusion printing machine is a device that can be applied to the surface precise coating process for various flexible substrates. The device can squeeze out the mold header of the Slot Die slit, the supplier system and the feed valve body, which can achieve continuous coating, gap coating, striped coating, grid coating and other types of coating requirements. Less, fast printing speed. The equipment has high accuracy, good consistency and stability, and can be used for sub -micron -level coating. It is widely used in thin film solar cells, lithium ion batteries, FCCL, optical film, graphene film, ceramic film, high -end tape, and various functions Film industry.
