Hot Metal Gas Forming

Hot Metal Gas Forming was first conceived as a low cost alternative to forming steel tubular components for automotive structures. The idea was simple, place a pre-bent tubular structure into a die cavity, inductively heat it and then expand the tube to the inside cavity shape using gas pressure. A proposal of the same name was developed and proposed to a NIST-ATP solicitation, and funding was secured in the fall of 1998.

The first technical paper on the Hot Metal Gas Forming process was given to a packed audience at the SAE conference / International Body Engineering Conference in September of 1999. A copy of that paper is attached below.
