Abstract
A method and/or system for forming a plastic bottle from a preform without the use of a mold or a complete mold are provided. The technique includes selectively injecting heat into the preform using narrowband irradiation devices emitting irradiation in a narrow wavelength band matching desired absorptive characteristics of selective portions of the preform according to a predetermined heat signature to achieve a three-dimensional heat profile in the preform. The heat profile corresponds to a desired shape of a finished bottle and facilitates self-limiting stretching of the selected portions of the preform to achieve the desired shape. Using the technique, air is selectively injected into the preform to form in free air the finished bottle having the desired shape.
