Process for the production of a coated tie rod (16) for a doorstop device (10) for vehicles, in which the tie rod (16) has an articulation hole (38) at one first end (16a) and a pair of rolling surfaces (20, 22) designed to co-operate with a pair of rollers (26, 28). The process comprises the steps of: positioning a metal core (34) in a moulding apparatus (44) and injecting plastic material into a moulding seat (50) surrounding the metal core (34). The metal core (34) is positioned with respect to the moulding seat (50) using first positioning means (52, 54) which co-operate with the articulation hole (38), and using second positioning means (60) which cooperate with an appendage (40) formed at a second end (16b) of the metal core (34).
