Progressive drawing die As a die forms a shape from a flat sheet of metal, there is a need for the material to move into the shape of the die. The flow of material is controlled through pressure
applied to the blank and lubrication applied to the die or the blank. If the form moves too easily, wrinkles will occur in the part. To correct this, more pressure or less lubrication is applied to the blank to limit the flow of material and cause the material to stretch or thin. If too much pressure is applied, the part will become too thin and break.
Drawing metal is the science of finding the correct balance between wrinkles and breaking to achieve a successful part.
General Draw Radius Guideline
| Metal Thickness | Minimum Radius | Maximum Radius |
| .015 to .020 | .156 | .250 |
| .021 to .030 | .187 | .281 |
| .031 to .040 | .187 | .312 |
| .041 to .050 | .187 | .343 |
| .051 to .062 | .250 | .375 |
| .063 to .093 | .312 | .437 |
| .094 to .125 | .344 | .468 |
As a general rule, 3 times of metal thickness can be used for a start point. If the part shows evidence of cracked, the tool has been machined metal safe, thus allowing for additional radius. The part specification may require a small radius under the flange that may be achieved with one draw, as opposed to several draws to size the radius.

FAQ
Q: What’s your manufacture capability?
---- We use Sodick/Charmilles to frabricate die inserts,dimension we can do is +/-0.002mm.
Q: Can you make all the dimensions are according to our design/samples?
---- We can guarantee that all the dimensions are made according to your drawing/sample.Please notice that dimension tolerence we can do is +/-0.003mm.
Q: Did the stamping die suit for my press machine?
--- The stamping die is made according to your press machine’s specification.Before start making die parts,we will send the design for your approval.
Q: What’s your advantage compare with other supplier’s on the market?
---- We are stamping factory,have a team contains die design,making,maintance and stamping production.We know how important the good mold for stamping production.
---- All our engineers are with more than 10 years working experience.They are more professional on precision stamping field.
---- All the die parts we made are by Slow-speed wire EDM,can gurantee the dimension.Many of them make it by middle-speed wire EDM/fast-speed wire EDM
