KNOW-HOW | DRAW FORMING

Deep drawing is a sheet metal forming process in which a sheet metal blank is drawn into a forming die by the mechanical action of a punch. It is a shape transformation process with material retention. The process is considered "deep" drawing when the depth of the drawn part is achieved by redrawing the part through a series of dies.

HTF develops commercial applications of this metal shaping process involving complex geometries with straight sides and radii. Typical core business of HTF are: i.e. nacelle lips (one-piece or sectors), frames, hatch pans, bulkheads, engine floor bays, and exhaust pipes.
 
HTF is able to evaluate and determine the limiting drawing ratio (LDR) for complex components; the part is inspected for critical areas. During severe deep drawing the material work hardens and it may be necessary to heat treat the parts to restore the elasticity of the material and continue the process. HTF has for this purpose its own NADCAP approved furnace.
 
HTF uses 3 dedicated hydraulic press machines to form parts up to 3.200L x 2.500W x 1.500H (mm) – 126 x 98 x 59 (inches)
