Draw forming is one of the net shape processes, and, as a result, many of the technology advances in the general field of manufacturing have not been as beneficial to draw forming as one would expect. All too often, such advancements as lean manufacturing, statistical process control, just-in-time, and six sigma, have not resulted in benefits for draw forming.
Increasing sheet metal component rigidity while reducing weight can be achieved by substituting steel with aluminum, magnesium, or titanium alloys; advanced high-strength steel (AHSS); or 3-D structured sheet metal.

Automakers are racing to introduce green technologies. Toyota is the leader in hybrid sales and plans to introduce two new models even though it will continue to lose money in the short and medium term. Instead of trying to outsell Toyota, GM has introduced flexible-fuel vehicles that run on E-85, an ethanol and gasoline mix.

Cosma International applies its own hot-forming technique to stamping automotive metal components such as A and B pillars, roof headers, roof rails, rockers, door intrusion beams, and bumpers, to meet new CAFE standards for weight, NHTSA requirements for strength, and to counter problems with springback in UHSS components.

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.

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.
