Maurer Magnetic AG (company of shareholders) invests in spite
of the crisis
At the end of September 2009, the Maurer Magnetic Company, a
family enterprise, was able to inaugurate their extension building
in Grüningen. The latest field of technology of the enterprise,
the demagnetizing technology, has thus found a new home.
This summer,
the Maurer Magnetic Company has been able to complete the extension
building for this new field of demagnetizing technology. More
than four million Swiss francs have been invested by the enterprise
into this new building, which has been constructed according
to minimal energy consumption standards. The extension building
was duly inaugurated at the end of September 2009. As a consequence,
the Maurer Magnetic Company, the new market leader of the degaussing
technology, is well equipped for the future.
Mr. Albert
Maurer, the company owner, confidently states: “we understand
magnetism and we are specialists in the field of demagnetizing.
There is nothing which is impossible.” The new technology of
changing field demagnetizing now enables the enterprise also
to demagnetize layer, plug and bulk materials in large scale
manufacture. This is more efficient and less time-consuming
than traditional technologies, which were based on the processing
of individual parts.
In order
to demagnetize physically correctly, four conditions must be
fulfilled:
– A high magnetic field
– The number of pulsations
– The precision of the amplitude characteristic, phasing out
to zero
– An appropriate frequency
“Traditional
technologies have been characterized by always one of the components
not properly functioning“, Mr. Maurer explains. “Often, the
magnetic field, that is to say the power, was insufficient.
In order to achieve optimal demagnetizing, however, all the
components must favorably combine.” The technology employed
by the Maurer Magnetic Company has achieved demagnetizing to
such an extent that no re-magnetization of the relevant parts
occurs.
Two examples, from
industrial application and railway technology respectively,
illustrate the employment of this demagnetizing technology:
“A leading
Swiss manufacturer commissioned us to demagnetize stainless
inoxidation springs, which were difficult to demagnetize, up
to a limiting value of <2A/cm “, Maurer states. Preliminary
tests with a crate full of bulk material did not only reach
the required limiting values without any problem, but also revealed
a further decisive advantage of productivity. “The customer
bought one of our devices
and now processes a large amount of their spring production
in our demagnetizing device before the cleaning. They have recognized
the fact that the cleaning process has become much more efficient
and faster, when the materials are previously demagnetized”,
Mr. Maurer explains.
The removal
of magnetism from steel parts, however, also finds application
in other fields. Electromagnetic rail brakes of locomotives
and rail coaches, for example, which are employed in cases of
rapid stops and emergency braking, magnetize the relevant rail
sections and cause the formation of a magnetic pole on the rail
screws. These magnetic poles inadvertently influence the sensors
of the railway compositions when these are overrun, which causes
signal interference of the train control and, at certain travelling
speeds, triggers an emergency brake.
This new
technology has been developed together with the ETH in the course
of the last years. With the many new patents, which have been
granted from all over the world, the Maurer Magnetic Company
has become one of the most innovative enterprises in the field
of demagnetizing. The systems are produced in Switzerland and
mounted in Grüningen.
