Press Marking - Squeeze Action Presses

Schmidt manufactures a variety of squeeze action press markers that offer a gentler marking action when closer control of stamping pressure is desired.
Squeeze Action Press Marking Benefits
Schmidt's squeeze action presses, with 5 to 15 tons of marking pressure, eliminate impact and reduce noise. By comparison to impact presses, these units are dramatically gentler for both the parts being marked and the tooling in the machine. There is no impact, no bounce, and no repercussion as the marking pressure is delivered in a straight, smooth squeeze.
Schmidt's Available Squeeze Action Presses
Schmidt offers two styles of squeeze action presses, the pneumatic Model A/O (air over oil) and the bench style Model 450. Our Model A/O (Air over Oil) marking press combines both pneumatic and hydraulic pressure to create an impact and squeeze action press all in one. These systems are available in 6 or 10 tons. The Model 450 is a more heavy duty pneumatic press and is available in four sizes.
