US12281887 - Ported press adapter press mandrel system and method of using same

A Ported Press Adapter Expand Mandrel System (PPAEMS) includes a Ported Press Adapter (PPA) as a significant advancement beyond the Expand Mandrel Window Riser (EMWR) by adding multiple radial holes to provide increased light intrusion, full 360° visibility, and balanced stress distribution with a pattern of port holes, slots, or other openings. Additional clarity is provided by an ancillary light source directed into the working area. Utilizing a small diameter Mandrel Holder (MH) allows for a wide range of mandrel diameters for installation in tight working areas (coax and progressive presses) and improves axially precision with a fine thread pitch.
