Problems solved by technology

[0010] Another disadvantage is that it is generally not possible, or at least extremely difficult, to fix the component on the periphery of the tank with this protruding weld seam
[0011] Additionally, the protruding weld seam requires additional material to form
This extra material not only increases the production cost of the tank, but also increases its weight

Embodiment Construction

[0055] in the following Figure 1 to Figure 8 In the example, the barrier elements according to the invention are cylindrical stringers. Of course, in other embodiments (not shown), barrier elements consistent with the present invention may be plates or square beams.

[0056] as in figure 1 In the example shown, a parison 1 made of plastic material is introduced between two mold parts of a mold 2 in an open position. The parison 1 is introduced into the mold 2, which simultaneously remains open / separated. The mold 2 comprises mold parts 3 , 4 . The mold parts 3, 4 of the mold have inner surfaces 3', 4' which correspond to the outer surfaces of the tank to be moulded. Figure 5 is along figure 1 Sectional view of A-A. In this embodiment, the mold parts 3, 4 of the mold each comprise Figure 5 The moving parts 5, 6 shown in. As will be seen hereinafter, once assembled, the pair of movable parts 5, 6 constitute a stringer (ie barrier element). In another embodiment (not...

Abstract

The invention proposes a method for manufacturing a fuel tank made of plastic material, comprising the steps of inserting a parison (1) made of plastic into an open mold comprising mold parts (3, 4) introducing at least one barrier element between the mold parts of the mold; and introducing pressurized fluid inside the parison for pre-blowing of the parison and abutting a part of the parison against the barrier elements (5, 6) to Said portion of the parison is prevented from being clamped between mold portions of the mould.

Description

technical field [0001] The invention relates to a method for manufacturing a fuel tank made of plastic material. The invention is particularly suitable for the manufacture of tanks for motor vehicles. Background technique [0002] Various techniques are known for manufacturing fuel tanks made of plastic materials. One known manufacturing technique includes the following steps in sequence: [0003] a) inserting a parison made of plastic material into an open mold comprising two mold parts; [0004] b) closing the mold by engaging the two mold parts; [0005] c) Before the mold is completely closed, a pressurized fluid (i.e. gas) is introduced into the inside of the parison for pre-blowing of the parison; [0006] d) final blowing of the parison by pressing the parison against the mold part of the mould, by means of a pressurized fluid, once the mold is fully closed; [0007] e) Open the mold and remove the tank. [0008] Typically, tanks manufactured according to this k...
