Abstract:  
This invention relates to methods and means of removing flashings, fins or the like or otherwise trimming parts particularly those made from thermoplastic and thermosetting synthetic polymeric materials, hereinafter sometimes referred to as "plastics"; and more particularly to improvements in methods and machines for such purposes using, in general, a technique of "freezing" selected portions of the parts so as to render the flash, fins or like parts brittle and therefore usceptible to removal.
