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

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
---- 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
---- 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
