  • Publication number: 20150287874
    Abstract: A metal template structure at least includes a frame, a supporting stainless wire cloth is disposed at an inner edge of the frame, a metal template is disposed on the supporting stainless wire cloth, and falling holes arranged in a printing shape are disposed on the metal template. The present invention is characterized in that: a feeding guide portion extends upwards from an upper periphery of each falling hole, an aperture of the feeding guide portion is greater than an aperture of the falling hole, and a periphery of the feeding guide portion and a periphery of the falling hole are connected in different forms such as a right angle surface, an inclined surface or a concave surface. By using a large aperture of the feeding guide portion and increasing the feeding guide portion, the thickness of the metal template is increased, so that more slurry can pass through the falling holes smoothly during printing, thereby achieving optimal falling effect.
