A method for forming a plastic support shell of a sole includes the steps of placing a sheet material into a first mold assembly; softening the sheet material; vacuum plastic molding; putting the plastic semi product into a cutting mold assembly; cutting the waste edge; putting into a trimming mold assembly; and trimming with a mechanical arm. The carrying mold and the pressing mold press against the inner and outer surfaces of the plastic semi product, and the restricting edge and the support edge are used to define a cutting line. Therefore, the plastic semi product can be firmly positioned and held tight, and then the mechanical arm can trim the plastic semi product under the guiding of the restricting edge and the support edge, which makes the trimming process easy and precise. |

The present invention is a method for manufacturing inflatable bladders for use in articles of manufacture. The method includes the steps of providing a first polymer film, applying a curable release coating to the polymer film in a pattern that corresponds to the configuration of the inflatable bladder, curing the release coating to the first polymer film, providing a second polymer film with the first polymer film to form a layered element such that the release coating is disposed between the polymer films, positioning the layered element between two plies of material, applying heat and pressure to adhere the polymer films together except in the area where the release coating has been applied to form an inflatable compartment surrounded by a sealed perimeter, and removing the plies of material from the adhered first and second polymer films. |
