The internal structure of the extrusion head is made into a cavity based on the theory of fluid mechanics to ensure uniform pressure at the extrusion seam;

Convenient installation and disassembly allows multi-directional adjustment of the coating process;

The gap between the extrusion head and the steel roller is adjusted by full closed-loop control;

The liquid slurry that is uniformly stirred and has a certain viscosity is transported through a precision metering pump at a constant pressure to the ultra-precision processed extrusion coating die. Through the casting effect of the internal cavity of the die, the slurry pressure on the straight line of the seam is consistent. It has the advantages of high coating accuracy, the slurry is not affected by environmental humidity, can achieve ultra-thick, ultra-thin and fast coating speed, and can achieve multi-layer coating.
