Abstract: Structures and methods for hindering molded part deformation during densification are discussed. Such devices and techniques can help alleviate stresses that tend to result in part deformation during firing, sintering, or other densification processes, and thus reduce the need for secondary straightening operations post-densification.

Abstract: A cold forging process and apparatus for reinforcing an end of a rectangular tube, including a close fitting, rectangular upper mandrel that inserts into the tubing. The upper mandrel has flared corners at the end attached to the upper die.

A lower mandrel positions and retains the die during forming. After forming the lower mandrel is used to eject the formed part, which may for instance be a trailer hitch housing.

Abstract: A process for forming an initial section or like component featuring a hollow interior to a final shape by high internal pressure in the sealed hollow interior using a medium that can flow. In order to shape-form the initial section featuring at least one corner region—preferably at least two corner regions—the wall sections adjacent to the corner region are preshaped in a curved manner—as viewed in cross-section—counter to the direction of applied pressure, and subsequently re-shaped by applying the high internal pressure of the medium that can flow, displacing the corner region in the direction in which the pressure is applied. To that end a section with hollow space delimited by section walls is employed in which two section walls define each corner region of the section cross-section, whereby at least one of the section walls at the corner region features a region that is curved in cross-section.
