A shock absorber pad of molded fibers for the drop casting of ingots, comprising a plate of molded fibers having an assembly of truncated cups disposed in files and rows connected by thick webs along their upper edges. The webs are perforated between the cups and have concave cylindrical ribs for stiffening purposes. The cups and ribs in one file or row are so dimensioned as to nest into the cups and ribs of the opposite edge of an adjacent pad. The bottoms of the cups can be solid or perforate. |
