Design, Manufacture and Sales of Slot Coating Dies

      Slot die coating technology is a method in which the coating liquid is supplied into the slot die and shaped into a wide and uniform film to deposit on a moving substrate. The technology has a wide variety of applications and is considered to be an extremely versatile means for the production of advanced optical-electronic products. The technology can be extended to simultaneous multi-layered coating for specific products.

      Many prominent companies that provide slot dies are good at machining and polishing metals, but the most critical issue for making a good slot die is the full understanding of the physical properties of all types of coating solutions, such as fluid rheology, evaporation rates and so on. WCC has extensive experience on managing various types of coating solutions and sound fundamental understanding on the rheological properties of coating solutions. The slot die designed and manufactured based on WCC’s unique experience is cost-effective and can operate with high efficiency. WCC promises satisfactory after service on related coating problems.
