Detailed Description

Super-accurate coating technology anticipates a next generation's needs! 1.The Characteristics of Die Coating *A coating liquid can be coated on the film directly. *The coating speed is faster than that of Roll Coating. *The coating thickness can be maintained accurately in both the width and length directions resulting in a very smooth film surface. *Since back up rolls are not used and the coating liquid is applied directly to the film, problems such a splattering are solved and higher coating speed can be attained. 2.Mitsubishi's Die Coater characteristics ---> Cemented Carbide Die Coter The Characteristics of Cemented Carbide Slot Die are; *The edge parts are made of ultra micro grain cemented carbide. *The use of cemented carbide improves the accuracy of the degree of the straightness of the edge. *The Slot Die maintains a sharp edge because of incorporation which have a diameter of no more than 1μm. ( Edge parts do not occur a burr.) *Due to the excellent processing technology, many different edge shapes including curves of high precision can be produced. *Edge processed lapping enables a stable coating surface that reduces the uneveness of the application. ---> Slit-Width Adjustment Mechanism *Adjustable slit width by micron order *Quantitative control by digital display 3.Edge Accuracy 1)The degree of straightness on a slot side --->0.002mm or below (overall length 1,100mm) 0.001mm or below (overall length 600mm) * With regard to an accuracy, we can determine the degree of accuracy upon consulting with you. 2)The degree of finished surface roughness at the edge A. R side edge ---> Ry (Rmax) 0.2S B. Flat side edge--->Ry (Rmax) 0.1S 3)The swell of top side at the edge 　 --->Wcm 0.1MIC
