Abstract
Process for molding of foam-based heels, rigid of polyurethane, which essentially is characterized by the fact that in the first phase of the process it is sprayed, at an air pressure of 0.77-2.1 kg/cm2, on the cavities of the mold, whose effective volumes are 32.8 cm 3, a thermoplastic synthetic polymer composition, so that the amount of pulverized composition is calculated to obtain by drying a continuous surface layer of 0.076 mm (0.003 inches) in thickness; the drying is carried out in an air circulation oven set at 51.66ºC (130º f), in a drying time of about 3 minutes.
