Tube Hydroforming Design Flexibility—Part VIII: Dimensional Stability

June 14, 2005 | By Gary Morphy

Whether they are producing automobiles or hydroforming press parts, designers, manufacturers, and assembly personnel are very concerned about dimensional stability. Surfaces and holes must be located in a specified range and smaller is better. Concern escalates as the drive to improve quality and reduce build tolerances and problems increases.

Tube Hydroforming Design Flexibility—Part VI

September 14, 2004 | By Gary Morphy

Tube hydroforming reshapes a tube from a normally round cross section to a desired shape. The final shape, usually rectangular, develops along the part length. The cross-sectional periphery may be consistent throughout the part and equal to the original tube, or it can be expanded in localized...

Tube Hydroforming Design Flexibility—Part III

April 24, 2003 | By Gary Morphy

The last article in this series noted that variable periphery design, or cross-section expansion, often is thought to be the most important aspect of tube hydroforming design flexibility. Expansion in the hydroforming die commonly is assumed to be the most efficient and most effective method,...

Tube Hydroforming Design Flexibility—Part II

October 10, 2002 | By Gary Morphy

It's difficult to overemphasize the importance of cross section expansion when you're talking about successful and innovative hydroforming of steel tubing. Overemphasizing one aspect of the tube hydroforming design process can take attention away from others and result in less than optimal design....

Tube Hydroforming Design Flexibility—Part I

May 16, 2002 | By Gary Morphy

Design flexibility is something that all automotive designers want, but too often they lack a thorough understanding of what that means—what aspects of design flexibility apply to a certain part and their effect on cost. A methodology often is adopted when (or even before) a part development...
