AIM Joraco TOGGLE-AIRE® presses combine the mechanical advantages of levers and toggles.  The ram force they generate builds as they reach the bottom of their stroke and effects a powerful shockless squeeze regardless of ram speed.  Forces produced don't rely on impact.  With an AIM Joraco 3 Ton press this power is over 300% greater than with a straight cylinder press of comparable size yet only 58% of the air is needed.  The stroke is also very precise with a ± .001" repeatability.  All this in a compact size, with the largest of our presses fitting on a 12" x 18" mounting area.

Why a Pneumatic Press?

AIM Joraco TOGGLE-AIRE® presses use fully pneumatic circuitry.  One connection to an air-line is all you need.  No clutches or brakes, no pumps, fluids or messy leaks associated with hydraulic or mechanical presses.  None of the hazards of electrical controls like shocks or sparks.  And pneumatic valving systems are completely compatible with any other equipment you may be using.  This flexibility plus their high power and quick response make them more suitable for today's applications than older straight cylinder presses.

What are the ways that TOGGLE-AIRE® presses can be controlled?

BEM Impulse Mode. 

In operation, this control method requires momentary actuation of the Synchro-Sig two hand unit to initiate the press cycle.  Once the press has been activated the ram will descend until it reaches the bottom of the stroke where the linkage stops against a positive stop before the press will reverse.  The ram will not return up until it reaches maximum strength and travel.  The BEM Impulse mode of operation insures a very accurate stroke and helps guard against inattention of the operator, loss of air pressure, improper loading etc., and maintains the quality of the work being performed.  Repeatability in this mode is plus or minus .001"

CSR Constant Signal Required Mode, Version 2.
This optional method of control requires that the operator's hands be held down on the SS-actuator for the full duration of the down stroke of the press.  If one or both hands are removed before the press ram reaches bottom the ram will instantly reverse and return to the top of the stroke and await a new signal from the two hand unit.  Once the ram has bottomed, it will automatically reverse.  This method of operation is especially useful in applications requiring slow ram speeds or special loading considerations.

SAR Stall Activated Reverse.
In this method of control the press ram reverses automatically as soon as it stalls, regardless of its position relative to the bottom of the stroke.  It is quite useful in coping with tolerance variations of parts to be assembled, die castings, etc., as the ram does not have to reach absolute bottom before it will retract.  it is important to remember that this can be used only if you have established that the press will have enough power to do the job in question throughout the full range of your parts, that is, both ends of the tolerances.  See the RAM FORCE tables for each model to determine how much power you will have at your disposal.  The SAR Stall Activated Reverse Mode is also very useful in delicate jobs.  By playing the air supply pressure against the depth setting of your tools you can, in effect, reverse the press when a desired maximum force has been developed and create a very delicate stroke which will not damage fragile parts, etc.
