Automatic impact presses make in-line part marking fast and easy. Consistent, controlled-depth stamping is accomplished on the production line for part numbering, branding, and serial numbering applications. Presses can also be used for such operations as punching, pressing, bending, riveting, and piercing.

  • Mark multiple characters in one stroke
  • Mount in any direction
  • Mark depth is easily controlled by adjusting the impact spring

Pneumatic presses are actuated with a solenoid valve or two-hand safety button switches.  The cylinders are double-acting, requiring air to be supplied for both the stamping and return strokes. A four-way pneumatic valve is required for activation.

The impact mechanisms can be used alone when space on the production line is limited.  The customer must design a way to move the mechanism and bring it in contact with the part to activate the impact spring.

Calculate the pounds of force required per character:

Character Size Annealed Brass Annealed Aluminum Low Carbon Steel Medium Carbon Steel Cast Iron Alloy Stainless Steel (300 Series)
1/16″  (1.6mm) 200 200 340 400 400 445
3/32″  (2.4mm) 400 400 680 800 800 890
 1/8″   (3.2mm) 600 600 1,020 1,200 1,200 1,300
5/32″  (4.0mm) 1,000 1,000 1,700 2,000 2,000 2,200
3/16″  (4.8mm) 1,400 1,400 2,400 2,800 2,800 3,100


Example:  Marking six 1/8″ characters into low carbon steel:  1,020 X 6 = 6,120 pounds of force required. The Model MB-21VP can be used, as it can apply a maximum of 7,700 pounds of force.
