Title:
PRODUCTION METHOD OF HOLLOW BODY, ESPECIALLY FUEL TANK
Document Type and Number:
Japanese Patent JP2016221964
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a hollow body, for preferably fixing an insert to an inner wall of a hollow body, while avoiding the insert from being crushed or damaged.SOLUTION: An insert for defining a sub volume in a hollow body is jointed to a shell, main pressure (P1') is applied to a main volume of the shell, then sub pressure (P2') is applied to the sub volume defined by the insert, in which pressure difference (P1'-P2') between the main pressure and the sub pressure is set to become larger than 0.2 bar and smaller than 3.00 bar.SELECTED DRAWING: Figure 5
