Re-cuts always ‘good as new’?
The main argument against re-cutting inserts in a wire mill’s internal die room is that
very few of these re-cuts are returned to an ‘as good as new’ condition. Most die rooms
simply lack the production and/or inspection equipment to guarantee consistent
control of the many important parameters in a wire die.
After extensive studies of thousands of re-cut dies received from hundreds of wire
mills around the world, Paramount has concluded that very few industry re-cuts are
manufactured properly to ensure
consistent and optimal drawing
performance. The wire die is a
very important part of the wire
drawing process and the same
level of consistency needs to
be maintained with both new
and re-cut inserts. Paramount
believes it has developed both
the process and equipment
necessary to ensure that re-cut
inserts are returned to an ‘as
good as new’ condition.
Another key argument against
internal re-cutting is that most die rooms do not have the volume per die size, or even
overall volume, to make re-cutting efficient. Most die rooms re-cut only a few dies to a
given size at any time, so require constant changeover.
Also, many die rooms do not remove
the ideal amount of carbide stock with
every re-cut.
Processing over 1,000,000 used inserts
every year, Paramount Die has highly
efficient and automated production
runs and claims to remove the optimal
level of material to guarantee clean up
of the wear zone without removing
more material than is necessary.

Replacing the internal
die shop
Ace American Wire Die has been
in operation for over 25 years,
manufacturing carbide round and shaped
dies with finished dimensions from .025"
up to 6". Ace American’s shaped dies
include standard shapes, spline, keystone
and trapezoids. The company stocks
a diverse inventory of carbide nibs to
anticipate customer die needs.
The company's engineering department
has over 50 years of die-making
experience and over 20 years of drawing
experience.
Engineers working for Ace American
have developed and manufactured many
different geometric configurations of dies
to give the best outcome with a variety of
material grades and incoming sizes.
Many companies are downsizing or
even eliminating their internal die
shops. In response to greater demands,
Ace American has increased its die
maintenance department, assuming
the role of an internal die shop for many
customers by maintaining their current
die inventory.
All Ace American Wire Die customers can
benefit from the company’s die re-cutting
service.
