Bühler Carat 560 die-casting machine. With the Carat 840 Bühler announced an even<br />
bigger machine for casting the entire front or back of future cars.<br />
BÜHLER DIE CASTING<br />
Larger machines revolutionize body-in-white<br />
production<br />
Bühler, Uzwil, Switzerland, is expanding<br />
its portfolio with the launch of<br />
Carat 560 and Carat 610, and the<br />
recently announced Carat 840 to meet<br />
the trends for larger and more complex<br />
parts.<br />
Structural components have clearly<br />
gained in importance in the automotive<br />
industry over the last years, with a<br />
trend towards even larger parts. This<br />
presents aclear opportunity for the<br />
die-casting industry. Larger and more<br />
complex parts produced in the die-casting<br />
process are acurrent trend. The<br />
automotive market is seeing the discussion<br />
of new body-in-white-concepts,<br />
with atendency to ever larger parts<br />
produced in aluminum die casting. This<br />
offers the possibility to functionally<br />
integrate various other parts, producing<br />
them in one shot, instead of in various<br />
production steps. This, in turn, reduces<br />
complexity and increases productivity in<br />
the automotive manufacturing process<br />
for the body-in-white. “We are seeing<br />
an entire front or entire back of acar<br />
produced in one shot, coming out of a<br />
die-casting machine every 2minutes.<br />
With this we see huge potential for an<br />
even more efficient production process<br />
for the automotive industry and afascinating<br />
opportunity for die casting,”<br />
says Cornel Mendler, Managing Director<br />
Die Casting.<br />
The new Carat 560 and Carat 610<br />
with locking forces of up to 61,000<br />
kilonewton (kN) are the latest addition<br />
to Bühler’s portfolio. In November<br />
2<strong>02</strong>0, Bühler announced the Carat 840<br />
–with alocking force of 84,000 kN.<br />
Imagine adie-casting machine as a<br />
big as ahouse, at6meters high and<br />
standing on afloorspace of over 60<br />
square meters. It is not only the dimensions<br />
that are impressive, but also the<br />
performance. “The Carat 610 is able to<br />
cast over 100 kg of liquid aluminum<br />
into adie within milliseconds, thereby<br />
holding the die tight by applying a<br />
force of 61,000 kN to it. This is comparable<br />
tohaving athousand elephants<br />
sitting on the die,” explains Martin<br />
Lagler.<br />
The Carat two-platen die-casting<br />
solution with minimum deflection and<br />
ahigh degree of dimensional accuracy<br />
has long-proven its value for the production<br />
of large and complex structural<br />
components. Equipped with the<br />
unique Bühler shot control system, for<br />
real-time closed-loop control, Carat<br />
enables the casting of parts of high<br />
quality, repeatedly, shot after shot.<br />
All the machines in the expanded<br />
Carat portfolio have the operator in<br />
mind. They are delivered with Bühler’s<br />
DataView control unit –which makes<br />
the control of the die-casting machine<br />
easier and more intuitive via its multitouch<br />
screen, making programing up<br />
to 25% faster. Additionally, every<br />
machine is equipped with Bühler’s new<br />
energy frame concept with aclear and<br />
distinctive arrangement of energy couplings.<br />
The Carat series also offers the<br />
option of servo drive technology.<br />
