摘要： Process for manufacturing a fuel tank (1) having a plastic wall, according to which:
1. a plastic parison comprising two distinct parts is inserted into an open two-cavity mould;
2. a core is inserted inside the parison, said core bearing two parts of a reinforcing element (3,4) capable of securing (creating a link between) two different locations inside the parison;
3. the parison is pressed firmly against the mould cavities (generally by blowing through the core and/or creating suction behind the cavities);
4. the two parts of the reinforcing element (3,4) are fixed at the two locations of the parison using the core;
5. the core is withdrawn;
6. the mould is closed again, bringing its two cavities together in such a way as to grip the two parts of the parison around their periphery in order to weld them together (2);
7. a pressurized fluid is injected into the mould and/or a vacuum is created behind the mould cavities in order to press the parison firmly against the mould cavities;
8. the mould is opened and the tank (1) is extracted;
9. an opening is made into the tank wall; and
10. through said opening, at least a third part of the reinforcing element is put in place in order to link/connect the two first parts together.摘要翻译： 制造具有塑料壁的燃料箱（1）的方法，根据该方法：1.将包括两个不同部件的塑料型坯插入开放的双腔模具中; 2.将型芯插入型坯内部，所述型芯承载能够在型坯内部的两个不同位置固定（形成连接）的两个加强元件（3,4）部分; 3.将型坯牢固地压在模具型腔上（通常通过吹过型芯和/或在型腔后面产生抽吸）; 4.加强元件（3,4）的两个部分用型芯固定在型坯的两个位置上; 5.核心被撤回; 6.再次关闭模具，将其两个腔体连接在一起，以便将型坯的两个部分围绕它们的周边夹紧以将它们焊接在一起（2）。 7.将加压流体注入模具中和/或在模具腔体后面产生真空，以便将型坯稳固地压靠在模具腔体上; 8.打开模具并取出罐（1）; 9.在罐壁上开一个开口; 和10.通过所述开口，加强元件的至少第三部分被放置就位，以将两个第一部分连接/连接在一起。
