The Ellwood Closed Die Group (ECDG) is launching a new product line for Seakeeper. The line includes finish-machined flywheels that are assembled into gyro stabilizers, which, according to Seakeeper, cut down “95% of all boat roll, the rocking motion that causes sea sickness, anxiety and fatigue.” Ellwood Texas Forge Navasota (ETFN) will use the entire Ellwood Group supply chain to manufacture the flywheels from start to finish.

Ellwood Closed Die Group completed a new manufacturing complex at its Navasota facility.

This article examines the application of screw presses for forging operations. An overview of screw presses and typical applications are discussed first, followed by the physics of their operation. Simulations are used to illustrate these various aspects, which cannot be directly observed during production. Other features and characteristics, which are important for the proper use and operation of screw presses, are also described.
