  • Patent number: 7914901
    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. In some instances, a support structure is utilized to orient a molded greenbody in a preferred direction to reduce deformation during firing (e.g., orienting a thin tail section is a plane parallel to the direction of gravity). The support structure can also be part of, or the entirety of, a thermal mass to help alleviate stresses that lead to part deformation. Though such structures and methods can be used for any molded piece, it can be particularly used to create a portion, or an entirety of, a medical device such as a jaw of an surgical instrument.
