Metal Slot Die

Manst specializes in the coating technology field. Starting from addressing customer product pain points and driving process innovation, it has gradually developed a diverse matrix of coating slot die products tailored to meet customer needs. These products offer personalized choices such as various adjustment methods, single-layer multi-slurry coating, multi-layer coating, and coating slot die made from different materials.

New Continuous Double-Layer Coating Die

The new continuous double-layer coating die employs a precision slot-die extrusion wet coating technology. It features two independent coating flow channels, allowling simultaneous double-layer coating for continuous dual-layer applications. Both the upper and middle parts of the die are equipped with electric actuators, enabling closed-loop adjustment of the transverse coating areal density.
