摘要： A method for the manufacture of a mold out of mold material from a previous blank by machining each blank into a desired shape by means of a machine tool controlled by a computer utilizing a dimensioning data set. Each blank is manufactured by feeding an organic polymer material whose melting point is preferably lower than 150.degree. C. in liquid form into a box-shaped container which is open at the top and which corresponds to the dimensions of the desired mold. Waste polymer material from the blank upon machining is recovered and heated to a temperature higher than its melting point, whereupon it is fed onto an existing mold no longer needed, so as to provide a new blank for a new mold.
