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.
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 drawn pressings
When you look at a stainless steel kitchen sink, a fuel tank for a car, or the outer casing of a lithium-ion battery, you are looking at a "deep drawn pressing." Despite the name sounding like a niche industrial process, deep drawing is the unsung hero of modern manufacturing. As the metal is bent and stretched, it
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. It wasn't welded, cast, or printed
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.
