ABSTRACT OF THE DISCLOSURE The present invention proposes a process for manufacturing an object intended to be held in the hand and which comprises a body made from a plastic material reinforced inside by means of a frame and comprising at least one grasping zone having a hardness less than that of its other parts. This process consists in plac- ing the frame in a mould comprising an injection aperture in the part of its cavity corresponding to the grasping zone of the object, clos- ing the mold, injecting into the cavity a definite amount of a com- pact plastic material, this amount being insufficient to completely fill the mould, then injecting an amount of expending plastic mater- ial to completely fill the cavity, the expanded plastic materiel, which while penetrating inside the volume of the non-solidified com- pact material, forces this latter to come into contact with the whole internal surface of the cavity of the mould and to cover the frame, and removing the object from the mould after cooling of the two plastic materials.
