End Forming Systems and Tooling Model 400 HPU Hydraulic Power Unit  Pressures from 0 up to 3,000 psi (207 bar)  Power source for tube end forming tools  Continuous duty cycle  Cycle times as fast as 2 seconds  Portable system mounted on casters  Manufactured to customer specifications APPLICATION DESCRIPTION The SelectForm® Model 400 Hydraulic Power Unit is designed specifically to meet the needs of Airmo End Forming Tooling. This power unit is equipped with valves and circuitry to reliably operate hand-held and modular end forming tools. The standard Model 400 Hydraulic Power Unit is supplied with an integral oil to air heat exchanger for cooling the hydraulic fluid, and provides for a continuous duty cycle. The Airmo SelectForm® hand-held or modular tooling can produce the end forms shown below. Either tooling style can be mounted to the top of the hydraulic power unit using optional stand and clamps. End forming tools are used for manufacturing processes in a variety of industries, including:  Aerospace/aircraft  On/off road mobile vehicles  Outdoor power equipment  Heat exchanger/radiator  Plumbing fittings  Military/defense  Tube and pipe mills SYSTEM CONFIGURATION COMMON END FORMS Expansion The SelectForm® Mode 400 Hydraulic Power Unit can be operated as a stand alone unit or in-line with other processes. OPERATION The SelectForm® Model 400 Hydraulic Power Unit when used with Airmo tooling is easy to operate. Simply insert the tube into the tool and actuate the electronically operated foot switch. The system cycles automatically, producing a finished form in 2 to 5 seconds. End forming tools can be quickly changed over using quick disconnect couplings.
