Isothermal Forging
Isothermal forging keeps both die and workpiece at the same temperature throughout the forming cycle — eliminating die chilling and enabling complex, near-net shape components in aluminum alloys...

Hot Forging
Hot forging is a metal shaping process that uses heat — typically 1,000°C to 1,200°C for steel — to reduce flow stress and enable complex deformation in a single press stroke. At these...

Progressive Die Stamping
Progressive die stamping is a metal forming process that shapes sheet metal strip into finished components through a series of stations within a single die set. Each station performs a specific...
