<p>The method for producing a series of containers (2) comprises the following steps: - heating a series of initial preforms (12), - injecting air into each heated preform (22) to form a series of containers (2). The method involves defining a strain parameter correlated with the internal strain of the thermoplastics material in the preform and defining a range of acceptable values for said parameter, the method comprising a step of analyzing each of the preforms (12), involving the following steps: - determining a value of said strain parameter, - comparing the determined value with the range of acceptable values, - emitting an output signal when the determined value is outside the range of acceptable values.</p> |
