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.
| Model | Maximum Stamping Force (tons) | Pneumatic | Drawing |
|---|---|---|---|
| MB-19VP | 1,300 lbs / 600 kg | ◼ |  |
| MB-21VP | 7,700 lbs / 3500 kg | ◼ | |
| MB-35VP | 16,500 lbs / 7500 kg | ◼ | |
| MEC-15/19 | 1,100 lbs / 500 kg | |

| MEC-32/35 | 14,300 lbs / 6500 kg | |
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.
