US Patent Issued to Southwest Research Institute on Nov. 3 for "Mold master fabrication for injection molding using physical vapor deposition, electroforming, and die-sink discharge machining" (Texas Inventors)

ALEXANDRIA, Va., Nov. 3 -- United States Patent no. 12,779,741, issued on Nov. 3, was assigned to Southwest Research Institute (San Antonio).

"Mold master fabrication for injection molding using physical vapor deposition, electroforming, and die-sink discharge machining" was invented by Samuel Joseph Blackshear (Lakehills, Texas), Albert Joseph Parvin Jr. (San Antonio) and Matthew Louis Capps (San Antonio).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method of fabricating a master mold for a part begins with using a physical vapor deposition (PVD) process to cover the part to be molded, thereby generating a conductive metal coating. Next, an electroforming process is used to thicken the conductive metal c...
