EXPERTS IN ROLL FORMING AND HYDROFORMING METAL FORMING EXCELLENCE

Roll Forming and Hydroforming

In June 2018 Hydram became part of the Dynamic Aerospace and Defense group with its headquarters in Michigan USA.  Dynamic have an established reputation, specialising in supplying precision metal components for the aerospace, defence, automotive and rail sectors, and having expertise in custom metal forming processes.

Roll Forming

Unique among all metal forming methods, the roll forming procedure allows a flat strip of metal to be progressively formed into a complex one-piece shape in a single operation.  This process assures a smooth flow of material from the first to the last phase and allows maximum dimensional control to the finished part.  Roll forming presents engineers with the utmost in design flexibility, freeing them from conventional shapes.  The process also frequently eliminates costly secondary sub assembly and fabrication operations.

Sheet Hydroforming

Hydroforming is a unique forming process that uses a rubber diaphragm or bladder as a universal female for all drawn parts.  The Hydroform produces exacting parts for all internal dimensions, with no outside tool marks that would be seen on a traditional steel on steel stamping process.  Parts are drawn into the rubber and produced through displacement pressure.  This means less costly tooling with shorter lead-times.  Most deep drawn parts are usually drawn in a single operation.  It is suited to exotic out-of-round shapes that spinning cannot produce.

Tube Hydroforming

Dynamic Group company, Dynamic Metals LLC (Elkhart US), offers tubular hydroforming (THF) for aerospace components.  For typical products, round tube is first bent to a radius before being inserted into a shaped metal die in the hydroformer.  One end of the tube is plugged and the other attached to the hydraulic pump.  Pressure is applied to the inside of the tube which is held in place by the dies until the tube obtains the desired shape. The image opposite illustrates finished hydroformed tube with a square cross section.
