Wheels Over Europe provides products
and services that are suitable for
responding to current trends in furniture
production. Semi-finished products
deliver benefits for the furniture
manufacturer that include shorter time
to market, and rapid prototyping in
tubular materials.
Using free-form bending technology,
the company produces structures that
are innovative, strong, slim and self-
supporting,making it possible toproduce
elegant designs with low thickness
ratios. The company uses high-quality
machines, automation, special software
and laser tube scanning, resulting in
reproducible free-form bends.
Tube is forced through the bending head
at a constant speed, to keep material
stresses in the product low.
The company’s core activity is supplying
tailor-made free-form bent tubes for less
than they would cost customers to
produce, working closely with Swiss
and German mechanical engineers to
develop new methods.
The company offers the following
options: mandrel-free bending; bending
with smooth transitions on round tubes
with an external diameter of < 31mm;
wall thickness between 3 and 10% of
the external diameter.
Tools can handle diameters of 10, 16, 19,
22, 25 and 30mm, with other diameters
available if the customer is willing to pay
all or part of the cost of the tools.
The overall maximum length of the
product is 4,000mm. Quotes can be
provided on the basis of CAD drawings
or IGES data.
Tubes are supplied on time, in the
quantities required, from small quantities
in line with the prototyping department’s
needs, or in large quantities for the
production department.
The company also handles the
purchasing of the tubes.
