Process for making a temple for an eyeglass frame, which comprises the following operational steps: - a step of arranging an elongated body made of a plastic material extended along a main extension axis; - a first heating step, in which said elongated body is heated up to its softening temperature ranging between 60°C - 100°C; - a step of housing said elongated body in a shaped concavity of a mold; - a step of arranging a metallic rod-like core of length equal to or less than said elongated body; - a second heating step, in which said metallic core is heated at a temperature ranging between 250°C-350°C; - an insertion step, in which said metallic core is inserted within said elongated body along an insertion direction substantially parallel to the main extension axis of said elongated body for at least one section of said elongated body; said process being characterized in that: - said housing step is preceded by a step of positioning at least one ornamental element in at least one seat provided within the shaped concavity of said mold, and in such seat said ornamental element is at least partially retained by shape coupling; - said ornamental element has at least one undercut portion which, at least in said housing step, is completely embedded in the plastic material that constitutes said elongated body; - subsequent to said insertion step, at least one coupling portion of said ornamental element remains visible once said elongated body is extracted from said mold; - said positioning step provides for inserting, with shape coupling of male/female type, at least one projecting element of the coupling portion of the ornamental element in a corresponding recess of the seat of said mold; - following said insertion step, once said elongated body is extracted from said mold, a removal step is provided, in which said at least one projecting element is at least partially removed; wherein, in said insertion step, said metallic core pushes the plastic material of said elongated body to occupy all the space available within the molding chamber, completely embedding a recess of the undercut portion of said ornamental element in said plastic material without moving said ornamental element from said seat, and in such seat said ornamental element is retained by said shape coupling. - a step of arranging an elongated body made of a plastic material extended along a main extension axis;
