Durable Technologies' manual impact presses are simple to set up, easy to operate, and offer excellent repeatability. They provide significant advantages in terms of control, safety, reliability, and are low maintenance.
If your volume of marking requirements increases your manual press can be converted to pneumatic power. To keep pace with changing production requirements and to minimize operator fatigue, all three manual press sizes can be equipped with a pneumatic package. This package is an affordable alternative to purchasing a new pneumatic press and includes a single-acting cylinder incorporated into a slide-on mounting bracket.
In addition to stamping and marking, our presses can be used for many other manufacturing applications including: riveting, staking, forming, punching, bending, crimping, piercing, assembling, broaching, and coining to name a few.
Durable Technologies can provide you with a turnkey impact press package including custom steel stamps, steel type, type holders, and manual or automatic numbering heads depending on your specific part marking requirements. We can also help you design a custom fixture for your parts to hold them safely and securely in place while marking.

Manual Press Principles of Operation
Since these presses operate on a spring-actuation principle, the degree of impact is easily adjustable. The press contains a spring that is compressed during energy section travel. Press capacity can be easily adjusted by increasing or decreasing spring size and/or tension. When the release point is reached, the compressed energy is discharged causing the internal hammer to deliver the powerful impact. There are a variety of sizes of springs available for each of our impact press models. Vertical travel is accomplished by a gear and rack arrangement.
with Numbering Head
Step 1 - The energy section advances towards the workpiece by gear rack and pinion, powered either automatically by double-acting pneumatic cylinder (if using a pneumatic unit with hand controls) or manually by the operator pulling down the lever.
Step 2 - Once the press stroke is engaged and the workpiece is contacted, the press stroke continues. The workpiece is held in place by the pressure from the energy section (this is a significant safety feature.) The impact spring is compressed and builds force as the press continues to maintain contact with the workpiece.
Step 3 - When the ball bearings reach their release point, the powerful impact is discharged. The impact spring delivers force to the hammer, which in turn strikes the plunger (tool holder.) You can control the amount of impact depending on which spring you choose and how much tension is applied.
