Abstract
A method of producing a container from a thermoplastic blank, including a step in which the blank is heated using at least one beam of coherent electromagnetic radiation, and a step in which the container is formed from the blank thus heated. The invention also relates to an installation which is used to produce containers and which includes a unit for heating the blanks in order to form containers from the blanks thus heated. The inventive installation defines a path along which the blanks travel inside the heating unit. In addition, the heating unit includes at least one coherent electromagnetic radiation source which is directed toward a zone that is located on the aforementioned path.
