- This second production method does not make it possible to obtain a connecting rod whose body and the screeds are simultaneously manufactured in the same material.
- the various assembled components form a non-homogeneous piece whose cohesion is likely to change due to an embodiment in different materials.
- a third method provides the realization of a rod from preforms and consisting of arranging the preforms around a support so that the junction edges of said preforms overlap, bonding said joining edges by sewing, and extracting said support and inserting in its place a casting core prior to placing the assembly within a mold and injecting resin under pressure into the mold followed by polymerization of the resin.
- this third method comprises several manufacturing operations including the polymerization step which lengthens the production cycle time of several products. hours.
- the present invention aims to overcome the drawbacks of the prior art and proposes a method of producing a connecting piece, such as a connecting rod, whose body and the clevises are simultaneously manufactured in the same material, said method comprising a number reduced operations reducing cycle times and therefore the production costs of said connecting piece.
