To make a wheel light and not lose its
strength is a great challenge. Roberto Marchesini has accomplished this
successfully for the past 40 years using magnesium. Magnesium is a very
delicate and refined material which few other foundries are able to work
with successfully. In 1959 Marchesini made his first set of magnesium
wheels for a Maserati, which was racing in Indianapolis. From that day
forward the volume of work and the Marchesini reputation has grown.
Roberto Marchesini is definitely the best in the production of magnesium
wheels. He doesn't say this himself but we believe it to be true, in
fact all of the Factory teams at the 2001 Daytona 200 used Marchesini
wheels.

| Forged Aluminum: |

| Unique
advantage of the Marchesini Three Dimensional Forging Process:
When you forge a piece you normally come straight down and cut the
part out like you would make a cookie from a cookie mould.
This process is called "open
die" forging and is the simplest and lowest cost way of
forging. You then have to machine out the well and bead area which
interferes with the fiber structure of the material causing a loss
of strength.
The forging process used to make
the Marchesini wheels uses a precision three piece mould,
"closed" die process which is "more expensive and
complex," to not only form both sides but also to form the well
and bead seat of the wheel. This process makes a superior wheel
with higher mechanical properties. However,
you can understand the complexity of making a three piece mould that
must have side sliders operating under 15,000 ton pressures. The
Marchesini forging three piece closed dies are precision,
complex, and very expensive. However, you receive the benefit of
this investment in technology.
The other advantage of the forged
wheels is that all surfaces are "machined" which creates a
precision wheel. The trueness of a forged wheel adds to the
overall performance of the wheel. |

| Sand
Casting:
Marchesini is the leader in developing sand casting techniques that
produce wheels with the highest mechanical properties for excellent
performance and value. This is proven by the fact that virtually all
of the leading Factory racing teams use Marchesini wheels.
Sand cast wheels are produced by a gravity casting process. However,
the gravity process does not normally provide pressure to align the
fibers of the magnesium for maximum strength. Marchesini has greatly
improved the gravity casting process by using 10 times the volume of
material in the mould so the weight of the additional material helps
create a stronger wheel. This is an expensive process because 9
times the weight of the wheel is scrapped.. The wheels are over
designed using more material to gain the mechanical properties
needed. This overall design concept and process is excellent and
offers the highest value for many applications. |
