A method of analyzing preforms for potential bursting during forming and filling by injecting an incompressible liquid to shape the successive heating preforms into containers and fill the containers. The method defines at least one stress parameter correlated to the internal stress of the thermoplastic material of the preform and defines a range of acceptable values for the stress parameter. The method includes analyzing each successive initial preform and each successive heated preform, determining a value of the stress parameter, comparing the determined value to a range of acceptable values, and emitting an output signal when the determined value is outside the acceptable range of values.

Method and machine for producing containers by injecting a liquid inside successive preforms

A method for controlling a molding unit () for the forming of a container made of thermoplastic material by blow molding of a preform, with the unit () including:

Method for controlling a molding unit

An installation () for thermally conditioning thermoplastic preforms () that are intended to be formed, the installation () including:&#x2014;a thermal-conditioning zone () divided vertically into a heating first part () which is intended to house a body () of the preform () and a cooling second part () which is intended to house a neck () of the preform ();&#x2014;a device () for cooling a portion of the preform () by producing a stream of gas passing through the thermal-conditioning zone (); characterized in that the cooling device () produces a blade () of gas blown with laminar flow through an axial outlet slit ().
