Method for manufacturing artificial leather shoe upper

A method for manufacturing an artificial leather shoe upper, comprising steps of:

• (A) preparing plural pieces of artificial leather upper material of a size needed;
• (B) setting a working temperature and a reaction time of a thermoforming machine having a upper die block and a lower die block for heating, wherein the lower die block has plural thermal dissipation grooves each having plural thermal dissipation holes communicated with a vacuum pump, and wherein the lower die block is provided with a removable upper pattern mold thereon;
• (C) placing the plural pieces of artificial leather upper material flatly and closely on the upper pattern mold by front surfaces of the plural pieces of artificial leather upper material towards the upper pattern mold as a temperature of the upper die block and the lower die block reaches the working temperature, and covering an air insulation plate on back surfaces of the plural pieces of artificial leather upper material and the lower die block for completely insulating the air and flattening the plural pieces of artificial leather upper material;
• (D) activating the vacuum pump communicated with the plural thermal dissipation holes of the lower die block for pumping out excess air of the lower die block to maintain the plural pieces of artificial leather upper material flatly and stably on the upper pattern mold;
• (E) thermoforming the plural pieces of artificial leather upper material on the upper pattern mold to soften the plural pieces of artificial leather upper material and form a pattern at the front surface of the plural pieces of artificial leather upper material and corresponding to the upper pattern mold by pressing and heating the upper die block on the lower die block, thus forming a semi-finished product having the pattern formed on the plural pieces of artificial leather upper material;
• (F) separating the upper die block from the lower die block after the thermoforming machine is heated for the reaction time, turning off the vacuum pump and removing the air insulation plate after cooling down to release an air insulation state, and demoulding the semi-finished product from the upper pattern mold;
• (G) fixed position scanning the semi-finished product by an image recognition process for determining a size of at least one coloring area and locations of at least one ventilation hole, at least one positioning hole and excess wastes thereof;
• (H) laser cutting the semi-finished product after the image recognition process to remove the excess wastes thereof, and punching the at least one ventilation hole and the at least one positioning hole thereon;
• and
• (I) placing the semi-finished product on a positioning template and using a 3-dimensional curved surface printing machine for precisely coloring the at least one coloring area, and removing the printed semi-finished product from the positioning template to obtain the artificial leather shoe upper.
