Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: introducing a molten amorphous alloy into a space between a mold and an etchable insert shaped to form an undercut on a part formed in the space and defining a protruding portion configured to form an opening in the part; cooling the molten alloy to form the part with the undercut and the opening; and removing the etchable insert from the part by: etching the etchable insert and drilling into at least part of the protruding portion.…
