DEFINITION

Classification: 164/284

(under subclass 271) Apparatus wherein the means shapes by a force other than gravity.

(1) Note. The term pressure shaping includes all force type operations of bringing the metal into contact with a shaping surface, e.g., centrifugal force, kinetic force, fluid pressure force, etc., except those operations where the only force is the static head of the casting material acting through a riser or gate, i.e., gravity force.
