Plate rolls keep rolling heavier plate

June 2, 2011

By:

These days, plate rolls are forming plate 6 and 7 inches thick--and even thicker. Vessel designs that would have been forged just a decade ago are now being sent to fabrication houses. The variable-geometry plate roll system, which really operates more like a press brake than a traditional plate roll, is making such extreme rolling possible.

The science of bending perforated sheet and tread plate

April 1, 2011

By:

Tread plate and perforated sheet present significant bending challenges. To help matters, fabricators may need to look beyond typical air bending with a punch and V die. Though bending alternatives vary, they have one commonality: They clamp down to ensure the workpiece stays where it should.

Processing AHSS with rotary bending technology

March 10, 2011

By:

The increased use of advanced high-strength steels (AHSS) have caused many fabricators to rethink the way they bend metal. AHSS have a relatively high springback associated with it, so much larger overbend angles are generally required. Rotary bending technology is a suitable way to product that overbend angle.
