Deep Draw Radius
Aware that the chosen deep draw radius can impact tool costs and per unit price, Professor Metal outlines a good rule of thumb for deep draw radius, when deep drawing metal into round, rectangular, or square shells.
How important is the radius?
The sharpness of radii can affect both tool cost and unit price
A Good Rule of Thumb
Round Shell: Bottom radius and draw die radius (radius under flange if there is to be one) should be four to seven times metal thickness.
Rectangular and Square Shells: Bottom radius and radius under flange, again, should be four to seven times metal thickness.
Corner radii should be eight to ten times metal thickness. If sharper radii are needed, additional tooling and operations will be required.
We Are Here to Help

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.”for a major manufacturer of waste oil burning heating systems
