  • Method and apparatus for continuous casting of polymerizable thermosetting material
    Patent number: 5260006
    Abstract: A method and apparatus for continuous casting of polymerizable thermosetting materials comprises mixing the materials with controlled amounts of two or more catalyst groups and passing said mixture through two or more series of heating stages. The initially gelled mixture which has not yet undergone excessive shrinkage is mechanically isolated from the ungelled mixture.
    Type: Grant

  • Method and apparatus for continuous casting of polymerizable material
    Patent number: 5183600
    Abstract: A method and apparatus for continuous casting of polymerizable materials that shrink during polymerization includes rapidly heating a moving matrix substantially uniformly throughout its cross section by radio frequency energy to initiate polymerization and maintaining the matrix thereafter in substantial thermal isolation such that substantially adiabatic polymerization occurs.
