The Deep Draw Process for Fabricating Metal
Deep drawing is a cost effective, high-quality method of fabricating metal components. It can replace other more costly forms of stamping, machining, tubing and casting, which require multi-process machining and increased material utilization. The deep drawing process saves time and money through the efficient use of material and the ability to perform multiple, complex steps in one machine and in one process.
The deep drawing process forms metal into complex shapes not possible with other forms of stamping. The process is accomplished by a transfer press, in which each station operates independently from the others. The first operation in a transfer press creates a flat blank, which is carried through as many as twelve or more operations, depending on the complexity of the part. The blank diameter is formed into the completed part through a series of draws, piercings, clippings, imprintings, and attachments to form threads or beads, depending on the part specifications. The blank is reduced through a series of draws in the multi-station press in order to facilitate its form, avoid material deformation, and end in a finished part meeting all the print specifications.
