Method of manufacture of a roughing in the drawings synthetic to the embodiment of the models and of prototypes and óoeuvre material, in this.
Method of manufacture of a roughing in the drawings synthetic to the embodiment of the models and of prototypes and óoeuvre material, in this.
The present invention relates to such a method consisting in producing a support frame (1) and in equipping it with means (2) of indexation on a machine for machining, in hermetically covering the frame (1), by immersion in a synthetic material (3) poured (cast) into a first adjustable mould, in allowing the said material to polymerise for a time lying between 8 hours and 24 hours at a temperature lying between 15 DEG C and 25 DEG C, then in arranging the frame (1) thus covered in a mould (4), the internal dimensions of which correspond to those of the preform, at a predetermined distance from the walls of the said mould (4) corresponding to the thickness necessary for the machining, in subsequently pouring a machinable synthetic material (5) not having a structural defect and becoming integral with the cover material (3), in allowing the said material (5) to polymerise for a time lying between 8 hours and 24 hours at a temperature lying between 15 DEG C and 25 DEG C and, finally, in demoulding the preform obtained.
