die geometry and associated equipment
Die Geometry and Associated Equipment
  • 100 mm (4 inches) in diameter / 50 mm (2 inches) in height
  • Various heat treat grades of H-13 tested todate
  • The dies were heated by 500 Watts electric Band heaters manufactured by Chromalox Inc., Pittsburgh, PA.
  • Die temperatures were 175°C (350 F) - Temperature was checked by an OMEGA touch probe temperature sensor (K type).
  • The dies were placed on fixtures consisting of two oil-hardened steel plates separated by steel blocks to ensure a passage for thermocouple wires.
