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.
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. deep drawn pressings
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. A deep draw press can produce 30 to 60 parts per minute
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. As the metal is bent and stretched, it
