Abstract
The invention relates to a method of producing a container from a thermoplastic blank (2), comprising: a step in which the blank (2) is heated using at least one beam (22) of coherent electromagnetic radiation, and a step in which the container is formed from the blank (2) thus heated. The invention also relates to an installation (1) which is used to produce containers (2) and which comprises a unit (16) for heating the blanks (2) in order to form containers from the blanks (2) thus heated. The inventive installation (1) defines a path (23) along which the blanks (2) travel inside the heating unit (16). In addition, the heating unit (16) comprises at least one coherent electromagnetic radiation source (26) which is directed towards a zone (25) that is located on the aforementioned path (23).
