Digital design modeling can be reliably used as a design aid in the thermomechanical processing of forged parts. In this analysis, models were used to simulate metal flow and thermal behavior while considering the possibility of cracking hazards and the prediction of structural behavior in the heat-treated steel. The simulation reduced scrap by 50%, eliminated potential defects and allowed the forging to be produced on a smaller press.
SECO/WARWICK will supply a multipurpose sealed quench-chamber furnace to Kuznia Sulkowicie SA, a Polish manufacturer of matrix forgings, construction connectors and manual tools. The furnace is designed for heat treatment (such as gas carbonitriding and pure hardening) in a controlled endothermic atmosphere. The fully automated operation of the furnace is its unique advantage. Personnel are only required to load and unload the work after treatment. The cycle and product transfer is completely automated.
Israel’s Bet Shemesh Engines Ltd. announced an agreement with Pratt & Whitney, a division of United Technologies Corp., to buy all the shares of Pratt &Whitney’s Carmel Forge for $58.5 million. Carmel Forge manufactures parts for aviation jet engines. As part of the deal, Carmel Forge has signed a long-term agreement, valued at $360 million over 10 years, for the production of forged metal-alloy components to be used in Pratt &Whitney’s new engine manufacturing projects.
Mettis Aerospace, Worcestershire, U.K., has been awarded a contract to supply steel alloy precision-forged components to Boeing’s first European factory in Sheffield, U.K. Boeing’s new facility will produce 7,000 actuation system components each month for the 737 and 777 passenger jets, which will be shipped for assembly in Boeing’s Portland, Ore., plant.
Often hidden beneath the skins of military aircraft, forgings were nonetheless widely used in the engines, ordnance casings and landing-gear assemblies of historic military aircraft, just as they are at the present time.
