Class Information
Number: 425/522
Name: Plastic article or earthenware shaping or treating: apparatus > Female mold and means to shape parison directly by internal fluid pressure, (e.g., blow mold, etc.)
Description: Apparatus particularly adapted to shape a preformed hollow workpiece including (1) a closed shaping surface facing radially inwardly adapted to be engaged by and to shape preformed material moving radially outwardly thereagainst, and (2) means to provide a fluent medium under pressure to the interior of the preformed workpiece, whereby the interior pressure exceeds the ambient pressure and causes the preformed workpiece to stretch and move radially outwardly into shaping engagement with the closed shaping surface.
