Forging

Forging Power and Control

The Oilgear Towler Company continues to maintain an unparalleled leadership role of providing makers and users of forging equipment with innovative power and control systems for the simplest to the most demanding of applications.
Since pioneering hydraulic press drives in the twenties, the Oilgear Company and the later acquired Towler Company have gained a wealth of successful hydraulic and electronic control expertise servicing the diversified needs of a variety of press builders and users throughout the world.
Today, by integrating state-of-the-art system control with either Oilgear time proven variable displacement pumps or Towler high pressure fixed displacement pumps, open and closed die press operators enjoy increased productivity, reduced downtime and energy efficient plant operation.
The Oilgear Towler Company’s partnership with the forging industry continues into the Twenty-first century with an enduring commitment of providing the latest advancements in forging power and control system technologies. We invite you to be a participant in this partnership.
The following features are found in new and retrofit forging systems supplied by Oilgear.

Hydraulic Systems Features

Fixed displacement and variable displacement Pumps

	Low maintenance
	High pressure capability
	10,000 psi (690 bar)
	Flow rate selection for horsepower limiting
	Simplicity for longer life
	Higher volumetric efficiency

Specially developed, large capacity sinusoidal servo controlled “Fast Forge” valve assembly provides:
