A new use for hydraulic presses

May 9, 2006 | By Andreas Kinzyk

The use of high-strength steels (HSS) and ultrahigh-strength steels (UHSS) has made stamping complex structural automotive components increasingly difficult and capital-intensive. Changing from traditional stamping (at room temperature on a mechanical press) to hot stamping (at elevated temperatures on a hydraulic press, with a water-cooled die for quenching) provides a suitable alternative for OEMs that produce these challenging parts.

Improving roll forming productivity of roofing components

May 9, 2006 | By Scott Tompson

Roll forming of roofing components for the pre-engineered building and component industries presents unique challenges for manufacturers. Tighter profile tolerances, wider product ranges, and compressed lead times present production challenges for producers running older equipment or those contemplating a move into this market. Some developments in equipment and processes that are important to producing secondary structural members include quick-change roll form tooling systems and tooling that can improve the productivity of roofing components- Cee's, Zee's, Eave Struts, Channel, and Base Angle.
