Press Marking - Impact and Squeeze Action Presses

For fast and efficient part marking, Schmidt offers both impact presses and squeeze action press markers that can indent a whole legend in one stroke.
Press marking machines are great for marking mild steel, tool steel, and soft aluminum parts. Press marking also offers some distinct benefits over roll marking, such as greater flexibility and more economical.
Two Types of Press Marking Machines
There are two basic types of press marking machines, an impact press and a squeeze action press. Impact presses, which can be faster than roll marking machines, indent numbers and letters into the surface of parts with a powerful single stroke. Impact presses are typically used for stamping plates or solid parts. Squeeze action presses offer a gentler marking action when closer control of stamping pressure is desired.
