Porta Press Selection Chart

The Porta Press can be used as a single station or multiple units can be installed as with the Gang Buster. Many customers seek to minimize the size of equipment for light duty applications. A row of Porta Presses can easily replace a massive press brake for tonnage and performance in light duty punching. The Porta Press must be looked at as an alternative to the OBI when buying a punch press.

The Porta Press is compact and light weight. At 150 lbs, it can easily be moved around the shop vs. the traditional OBI at 1,000 lbs that becomes a permanent fixture when it is first located.

The Porta Press frame has plenty of vertical adjustment at 5” with a maximum open height of 10” and 5” minimum versus the OBI at typically 2” for a similar tonnage machine.

Ram stroke varies from .625” to 3.5” over a number of tonnages. Generally the longer strokes are desirable as these exceed the typical OBI stroke.

Double acting cylinders are available that will pull open the die set like the OBI. These cylinders are equipped with a spigot. All other cylinders are single acting pushing down and the die set is opened by springs.
