Metal Alloy Injection Techniques

摘要

Metal alloy injection molding techniques are described. In one or more implementations, these techniques may also include adjustment of injection pressure, configuration of runners, and/or use of vacuum pressure, and so on to encourage flow of the metal alloy through a mold. Techniques are also described that utilize protrusions to counteract thermal expansion and subsequent contraction of the metal alloy upon cooling. Further, techniques are described in which a radius of edges of a feature is configured to encourage flow and reduce voids. A variety of other techniques are also described herein.

1. A method comprising:
injecting a metal alloy into a mold having a plurality of molding portions that define a cavity that corresponds to an article to be molded, the article including walls with a thickness of less than one millimeter with one or more features disposed thereon having edges with a radius of at least 0.6 millimeter; and machining at least a portion of the radius of the edge to define the feature of the article after removal of the metal alloy from the cavity.
