Powerful Magnetic Formwork from RATEC Used Worldwide in Prefab
Construction Industry
used to create the different inner
workings of the stations. The
formwork has more than 60 tons
of lifting force that is transferred
over four cylinders. Because
the formwork can cover different
lengths, heights and shapes, it is
suitable for all common transformer
types that the company
manufactures.
Over the years, RATEC has
developed an impressive lineup of tools and accessories in
support of its technology. Its " magnet in the box " , Pro-Magnet,
is the basis of all its ideas, says the company.
From a housing development in distant Peru to a transformer
manufacturing plant just four hours up the autobahn, powerful
molds from RATEC of Germany demonstrate how one
company's clever magnetic engineering can bring change to
a traditional industry such as prefabricated construction. By
introducing extremely powerful precision magnets to position
and fix the formwork, it has brought new capabilities and efficiencies
to the market.
Recent reports from the company illustrate how its magnetic
formwork is being applied to a variety of projects. The image
above shows a mold being completed at the company's
plant in Hockenheim that will help build two-room modules at
a modular housing factory in Peru. About nine years ago, the
first modular housing project in Peru went into operation using
RATEC molds to build 3,600 homes. This mold was destined
for a second production facility to build a new project in the
north of the country.
" We are very pleased that our customer
has once again decided in favor of quality
" Made in Germany " . Our equipment ensures
that the customer can produce at the very
highest of standards - and with the utmost
in efficiency " , says Joerg Reymann, managing
director of RATEC GmbH and Reymann
Technik GmbH.
Pro-Magnet, the essential
building block
Standard magnets of the ProMagnet
series are the foundation
of its magnet components
and shuttering systems. Inhouse
magnet production allows
them to be tailored to customer
requirements and for special
solutions. In addition to standard
variants with a retaining force
of 990, 1980, 2970 or 4620 lb,
RATEC can also implement
other designs and magnet strengths as required, or adapt
the installation components structurally without losing retaining
force. High performance neodymium magnets are used,
installed in-house in a patented process. Stainless steel
bandages and various coating steps and processes make the
magnetic core extremely corrosion
resistant.
The KPB Klacker Power Box is a
switchable shuttering magnet for
precast concrete plants which has
a Pro-Magnet integrated into it.

RATEC formwork for
transformer stations
In another example, last August
RATEC completed its third successive
delivery of formworks
to a transformer manufacturer
located north of Hockenheim.
Beginning with the first project in
2018, RATEC has now equipped
all three of the company's sites
in the country.
The design is extremely variable,
allowing the customer to produce two transformer station
sizes with a single formwork while at the same time enabling
different design variations. Interchangeable attachments are

The company's Easy Form siderail
system brings several of
the products together to enable
dealing with a wide variety of
situations. Designed as a modular
system, it can be easily used
even with just a few components
or in combination with a range of
accessories.

Magnetic chamfer and reveal
strips
Among the accessories are
magnetic chamfer and reveal
strips for quick and clean formation
of chamfers, drip molds or
dummy joints. The strips are
made of high-quality steel with
built-in magnets so that screwing
or welding on the table or on the
formwork can be omitted.
