Drawing Metal & Metal Forming

Deep Drawing is the process of forming a metal part from sheet stock, or a metal blank. In this lesson, Professor Metal explains how deep drawing, multiple deep draws and hydroforming produce metal cups, cans, pans, domes and shaped metal products.

Deep Drawing is the process of forming a part from metal sheet stock, commonly referred to as a blank, around a punch as it is drawn through a die. The edges of the metal blank are restrained by a "BLANK HOLDER" or a sleeve in the case of a redraw. Since the state of the art does not allow us to go as deep as we might need to go in one draw operation we can institute a redraw, whereby we reduce the diameter and increase the height of a previously drawn shell. There are many shapes that can be made through deep drawing such as cups, pans, cylinders, domes & hemispheres, as well as irregular shaped products. The terms Hydroform and Deep Draw are many times used interchangeably, with Hydroform now being the industry "buzz word" for metal forming. Both process offer their own unique advantages to metal forming.

Why Do We Choose Amalco?

“Amalco offers a 'one-stop shop'. In the past, our combustion cones were shipped back and forth between several subcontractors to have them perform different production steps. Amalco performs each of these operations at one facility, thereby reducing our cone supplier base from three to one. Now, we coordinate inventory and communications with only one cone supplier, which saves us invaluable time and resources.”
