Personalized jigsaw puzzle is not only a picture, but a story, a memory and a warm feeling. Each piece of the piece has its own position, like every recollection has its story, you have to put it in the exclusive place, the release is slowly enriched, the misplaced can not be complete.Most modern jigsaw puzzles are made of cardboard, making it cheaper and easier to make. The pattern of the jigsaw puzzle is the whole piece of art printed on the surface of the cardboard before cutting. The content of the picture can be a magnified piece of photography, painting, or other kind of graphic art. The printed board will be sent to a special embossing machine. The machine tool is equipped with a set of steel cutter groups according to the predetermined pattern. The cardboard will be cut into zero pieces by the tool group after the machine is punched. This process is quite similar to the forming process of graphic biscuit, and the difference is that the impact force of the puzzle printer is much higher. For example, the typical 1000 pieces of jigsaw puzzle, in order to make the cutting tools on the die completely cut the cardboard, require the machine to run up to 700 tons of pressure. The punching die (plate) of the jigsaw is usually made of a plywood type plate. The mold craftsman first portrays or cauterizes the groove on the template, then inserts the blade into the groove and spells it into a cutting tool group. The surface of the cutting tool group is also covered with a layer of elastic material, usually foam rubber. Its purpose is to print cardboard pieces from the pores of the cutter group after printing.
