Metal Alloy Injection Molding Protrusions

A molding device comprising:

• a mold having a plurality of molding portions that define a cavity that corresponds to an article to be molded using a metal alloy that is injected into the mold, the mold defining:
• a portion of the cavity that defines a feature for the article having a thickness that is greater than a thickness of an area of the article defined by the cavity that is proximal to the feature;
• and
• a protrusion for the article aligned on a side of the cavity that is opposite to a side including the feature, the protrusion being sized such that upon solidifying of the metal alloy that forms the article, the protrusion reduces an effect of thermal expansion on the side of the article that is opposite to the feature.

An apparatus comprising:

• an article formed using a metal alloy that is injected into a mold, the mold having a plurality of molding portions that define a cavity having:
• a portion of the cavity that defines a feature for the article having a thickness that is greater than a thickness of an area of the article defined by the cavity that is proximal to the feature;
• and
• a protrusion for the article aligned on a side of the cavity that is opposite to a side including the feature, the protrusion being sized such that upon solidifying of the metal alloy that forms the article, the protrusion shrinks to form a substantially flat surface to the side that is opposite to the feature.
