Abstract: A method of manufacturing a thin amorphous alloy strip with notches, the method comprising forming notches on a smooth amorphous alloy strip using a cutting roller in a notching operation, wherein the cutting roller has a cylindrical body, the body is provided on the surface with at least one spirally extending cutting edge; and during the notching operation, the cutting roller is pressed against the amorphous alloy strip and rotated, wherein an incident angle of the cutting edge is in the range of 20°-30°; a notching pressure is in the range of 5-8 g; and an extension direction of any point on the cutting edge has an angle in the range of 20-60° with a travel direction of the amorphous alloy strip.

Abstract: A plastic table board includes a top panel and a reinforced frame, wherein an edge of the top panel is equipped with a downward-extending side edge, the reinforced frame is located below the top panel, an outside edge of the reinforced frame is closely adhered to the side edge of the top panel; the outside edge of the reinforced frame is provided with a first plane, a connecting surface and a second plane, the connecting surface is an inward-bent cambered surface for connecting the first plane and the second plane; the first plane and the side edge of the top panel are located at a same vertical plane, the second plane is fixed with an inner wall of the side edge of the top panel, and a bottom end of the side edge of the top panel is located above the connecting surface.
