Deep Drawn Pressings Today

Next time you wash dishes in a stainless steel sink or start your car, take a moment to appreciate that seamless, curved bowl. It wasn't welded, cast, or printed. It was drawn.

Deep drawing creates a part from a single piece of metal. There are no welds, seams, or joints. This makes the part watertight, airtight, and structurally sound under high pressure. deep drawn pressings

A deep draw press can produce 30 to 60 parts per minute. Once the tooling is paid for, the unit cost drops to pennies. Compare that to a CNC machine taking 15 minutes per part. Next time you wash dishes in a stainless

Let’s pull back the curtain on the fascinating world of deep drawn pressings. In simple terms, deep drawing is a sheet metal forming process. A flat "blank" of metal is placed over a die. A punch pushes the metal into the die cavity, forcing the flat sheet to take on a three-dimensional shape. Deep drawing creates a part from a single piece of metal

Looking for a supplier? Always ask potential vendors for their "drawability ratio" (blank diameter / punch diameter). A ratio above 2.5 usually requires multiple draws.

As the metal is bent and stretched, it undergoes "work hardening." The walls of a deep drawn part become stronger than the original sheet metal. You get a part that is lightweight but incredibly rigid.

We live in a world obsessed with 3D printing and CNC machining. But when you need to produce 50,000 identical, seamless, incredibly strong metal enclosures at lightning speed, nothing beats a punch press and a die.
