Air-Mite AP4 1-1/2 Pneumatic Punch Press Fixture 120 PSI Two-Hand Custom Tooling

Air-Mite AP4 1-1/2 Pneumatic Punch Press Fixture 120 PSI Two-Hand Custom Tooling

The Air-Mite AP4 is a benchtop pneumatic punch press built around Air-Mite's AP-series air cylinder, rated to a maximum of 120 PSI. This unit is mounted on a heavy steel base plate and configured as a complete custom production fixture, with a two-hand anti-tie-down palm button control system as required by OSHA regulations for air-operated presses. The assembly includes a solenoid valve manifold, an SMC dial pressure gauge, and a pneumatic regulator for adjustable output force. Two custom black angled V-groove tooling blocks with locating pins are included, indicating this was set up for a specific part or assembly operation.

Applications

Air-Mite AP-series pneumatic presses are used in light manufacturing, assembly, and fabrication environments for operations such as staking, riveting, inserting, marking, and forming. The AP4 cylinder delivers controlled, repeatable downward force using compressed shop air, making it well suited for benchtop production fixtures where consistent stroke force is needed without a full hydraulic or mechanical press. The two-hand control system is a standard OSHA safety feature for air-operated presses, requiring both of the operator's hands to be occupied during the press stroke to prevent accidental injury. The custom V-groove fixture blocks included with this unit suggest it was previously configured for a specific round or tubular workpiece alignment and punching or staking operation in a production or prototype environment. Air-Mite has manufactured pneumatic cylinders and small presses in Chicago since the mid-twentieth century and their AP-series components remain in active use across light industrial and electronics assembly applications.
