Process for manufacturing a fuel tank

摘要

A process for manufacturing a plastic fuel tank including at least one component, by molding a parison using a mold including two impressions and a core, the process including: introducing a parison into the mold impressions; introducing a core inside the parison, the core having a moving device including the at least one component closing the mold so that the impressions come into leaktight contact with the core; pressing the parison against the impressions by blowing through the core and/or applying a vacuum behind the impressions; fastening the at least one component on an inner wall of the parison; opening the mold to withdraw the core; and final molding the parison by blow-molding and/or thermoforming; and to enable its fastening to the parison, the component is moved away from the core by the moving device through a combination of a rotational motion and a linear motion.

1. A process for manufacturing a plastic fuel tank including at least one component, by molding a parison using a mold including two impressions and a core, the process comprising:
introducing the parison into the mold impressions; introducing the core inside the parison, the core including a moving device fitted with the at least one component; closing the mold so that the impressions come into leaktight contact with the core; pressing the parison against the impressions by blowing through the core and/or applying a vacuum behind the impressions; fastening the at least one component on an inner wall of the parison; opening the mold; withdrawing the core from inside the parison; and finally molding the parison by blow-molding and/or thermoforming; wherein to enable its fastening to the parison, the component is moved away from the core by the moving device through a combination of a rotational motion and a linear motion.
