A die for use in an induction heating workcell incorporates segments of the induction coil in spaced array within a cast ceramic or phenolic body. A peripheral compression frame, typically of phenolic, surrounds the die body and applies a compressive load to the body through lateral and transverse reinforcing rods that are cast into the body. Matched dies close to trap heat in a workpiece at the center of the induction coil.

A die for use in a forming apparatus that uses inductive heating, the die comprising: (a) a cast phenolic or cast ceramic die body having a forming surface, the die body not being susceptible to inductive heating; (b) a plurality of lateral and transverse reinforcing rods extending through the die body in separate planes, the reinforcing rods being formed of a material that is not susceptible to inductive heating; (c) a peripheral compression frame around sides of the die body for imparting a compressive force to the die body through the reinforcing rods; and (d) induction coil segments embedded within the die body adjacent the forming surface.
