This invention provides a sheet-formed tableware and its manufacturing method. The tableware includes a main body and a handle, with the main body located at one end of the handle. Both the main body and the handle are formed by molding or vacuum forming from a single sheet of material. The tableware is formed in one pass by a die. Along the length of the tableware, one part is a punching area, and the other part is a shearing area. The die has a movable mold and a punching block that can move relative to each other. The punching block has a punching surface for punching the tableware. The punching surface corresponding to the punching area of ​​the tableware is perpendicular to the movement direction of the movable mold, and the punching surface corresponding to the shearing area of ​​the tableware is inclined to the movement direction of the movable mold. The manufacturing method of the tableware includes making a blank of the sheet material, molding or vacuum forming the blank into a three-dimensional shape, placing the sheet material in the die, and moving the movable mold towards the punching block, so that one part of the sheet material is punched and another part is sheared, obtaining the tableware in one pass. This invention can reduce the manufacturing cost of tableware and makes the tableware smooth and strong.
