Abstract
Provided in an embodiment is a method for molding, including: providing a molten alloy in a space between a mold cavity and an etchable block shaped to form an undercut on a part formed in the space, cooling the molten alloy to form the part with the undercut, and etching the etchable block. An undercut is a beveled edge caused by an etchant attacking an etchable block laterally and optionally vertically. The formed part can be made of a bulk amorphous alloy. In some cases, the etchable block can also be used to form at least one threaded portion in the part.
