Inoex, Germany, is a specialist in
measuring and control technology
and process engineering in the plastic
material industry. The company’s systems
are finely tuned to requirements in pipe,
profile, cable and film extrusion.
The automotive industry and many other
industrial sectors set high demands on
multi-layer products. As a consequence,
the production process is complex for
products such as brake hoses and floor
heating pipes.
Extremely thin barrier and functional
layers are frequently required to
provide tube and pipe with their specific
mechanical and chemical properties.
Conventional
ultrasonic
measuring
techniques have measuring limits at
approximately 0.2mm. iNOEX has
introduced a new technology where the
bottom measuring limit is 0.05mm.
Barrier layers prevent oxygen, for
example, from penetrating into the pipe,
or volatile components from leaving
it. These layers provide products with
special mechanical and chemical
properties.
In order to reduce cost, the aim is to make
these layers as thin as possible but as
thick as necessary. This can only be done
when wall thickness is controlled during
production.
Inoex has further developed proven
ultrasonic measuring principles, allowing
function and barrier layers that could not
be measured in the past to be precisely
controlled through intelligent ultrasonic
sensor technology, combined with
new algorithms and digital measuring
techniques.
Even data of extremely thin-walled
pipes can be precisely recorded, which
means that high safety regulations can
be adhered to and quality demands
fulfilled.
Ultrasonic measurement has previously
been based on the determination
of ultrasonic transit times inside a
product.
Through digitalisation the complete
signal is now recorded, improving signal
evaluation and further processing.
The complete recording of the signal
makes results highly precise, and supplies
full information on the product.
