Abstract: A process for manufacturing a plastic hollow body by molding a molten plastic parison, which is extruded vertically through a die, in a mold comprising two complementary cavities, characterized in that the die is adjusted so that the shape of the parison matches that of the mold cavities. A die suitable for such a process.

Abstract: Process for manufacturing a plastic fuel tank equipped with an internal line by molding a parison using a mold comprising two cavities and a core, comprising the following steps: introducing the parison into the mold cavities; introducing the core inside the parison, said core having first been fitted with the line; closing the mold so that the cavities come into leaktight contact with the core; pressing the parison against the cavities by blowing through the core and/or applying a vacuum behind the cavities; fastening the line to the parison over at least two points using a device attached to the core; opening the mold to withdraw the core; and carrying out the final molding of the parison by blow molding and/or thermoforming, in which the line comprises, between its fastening points, a free length that is capable of coming into contact with the parison and/or with an accessory found thereon when the mold is closed, and wherein during the fastening step, at least one intermediate fastening point is created u

Abstract: Method for detecting defects in a plastic vehicle tank equipped with internal accessories located inside the tank. The method comprises at least the following steps: a) providing the tank equipped with said internal accessories; b) making a digitized X-ray image of said tank; c) providing a reference image of said tank; d) comparing the digitized X-ray image and the reference image by means of a computer vision software; e) deciding on the presence of defects when differences exist between the digitized X-ray image and the reference image.
