Title:
容器をブロー成形するための方法および装置
Document Type and Number:
Japanese Patent JP2012508658
Kind Code:
A
Abstract:
A method and an apparatus for blow-molding containers are disclosed. A parison made of a thermoplastic material is first subjected to a thermal treatment in the zone of a heating section along a conveying path. The parison is then shaped into the container within a blow mold under the effect of a blowing pressure. Once the container has been blow-molded, a wall thickness is measured on at least one vertical level of the container. A preset value for the wall thickness is fed to a controller as a desired value, and the measured wall thickness is fed thereto as an actual value. The controller presets the quantity of at least one parameter influencing the blowing process in accordance with a difference between the desired value and the actual value. More specifically, the controller presets the quantity of at least one parameter influencing the supply of blowing gas. The quantity of the parameter is preset on the basis of a blowing process simulation model implemented in the controller.
