will form the resin 39 s exposed top surface into a flat configuration thus the cured strap 1 will have one flat surface 4 for injection molding the mold is preferably made from tool steel the mold contains an opening having two segments the first segment comprises a flat surface that corresponds to the desired flat surface 4 of the strap 1 the second segment comprises a shape complementary to the contour of the remaining cross section of the strap 1 the fabrication process for the injection molding embodiment follows the well known procedures for injection molding described in many reference books such as rubin irvin i injection molding theory and practice john wiley amp sons inc 1972 in this case a thermoplastic elastomer preferably polyurethane in the form of pellets is used the pellets are melted in the injection molder and then injected into the injection mold which is set at room temperature or at a temperature no more than 150 u00b0 f after a brief cooling cycle the mold opens and the molded part is ejected from the mold by use of well known ejection pins producing the final strap 1 because the mold cavity has one flat surface one surface of the cooled elastomer will have a flat configuration thus the produced strap 1 will have one flat surface 4 the strap 1 may be used as a belt as shown in fig1 in this use the strap 1.
