Abstract: In our search for die-materials that are not restricted by limitations of size, in the process of producing sufficiently large masses by explosion forming, we have adopted a form of construction in which epoxy-faced concrete is used for the die-cavity. This kind of technique is used to make a plaster master of the die-cavity, which is then coated with epoxy resin, reinforced with fiber glass. An adequate amount of reinforcement rodding and steel plates has its place in construction. The method of making dies for large and complicated components, using the explosive- forming technique is described here.
