Everything has its limitations. The thickness, toughness and elongation of acrylic board determine the ultimate elongation at break of this material. The ductility and extensibility of the acrylic board depend on the proper temperature, the size of the characters and the number of strokes, which all determine how thick the characters can be sucked out. No one can do anything that goes beyond the limit and goes against the laws of nature.
In Inner Mongolia, the "Peng lettering method" can complete the 6 cm limit of most Chinese characters in China in an area of one square meter. To solve this problem, we need to overcome two points, 1, that is, the plate keeps the optimum temperature continuously, and the plate cannot change temperature during stretching. 2. The lubricity of the male mold can prevent the acrylic plate from breaking. Peng used a soft thermoplastic molding machine to automatically wrap the male mold, and at the same time pushed the acrylic board into the hollow female die. The wooden male mold is not in direct contact with the acrylic board, so it has soft lubricity and will not puncture or break the board.
This ingenious idea has made the production technology of 3D perfect plastic characters, which has been included in the national invention patent.
