Winner: Tie Rod Frame

In the past, the C-frame press design made it easier to feed in product or change dies. The downside of the C-frame is deflection – where the frame will bend outward under the pressure of the load – which will cause deformities in your part, and ultimately lead to inconsistent and erroneous parts. In our ammunition case manufacturing equipment we need absolute precision and a lot of force. So we needed a better solution.

The result is the development of a modular H-frame frame press. The H-frame consists of blocks, tie-rods and spacers. With this press we are able to achieve .001 shut height accuracy with 20 ton’s force; and due to it’s modular design we are able to mount the press to an automated dial table and index parts through it.  Now, with the ability to run parts through an H-frame press we can produce precision parts with high tonnage and minimal deflection in an automated application.
