Inspection, Measuring, Testing & Marking
96 March/April 2007
Sikora, Germany, offers a range of precise
measuring and testing devices for tube
and hose extrusion. For continuous online
quality control of tube and hose, the
company provides state-of-the-art devices
for diameter, wall thickness, eccentricity
and ovality measurement, and detection
of lumps and neck-downs directly on the
extrusion line.
Important for extrusion operations, Sikora
technology features outstanding quality and
reliability, through the use of advanced X-ray
and laser technology with no requirements
for calibration. The use of very fast digital
signal processors eliminates the effect of
vibration or environmental influences. This
ensures unprecedented accuracy and long-
term stable measurement data.
The company presents the measurement
data through operator friendly display
and control interfaces. The display
options provide simple to comprehensive
statistical analysis, data collection and print
capabilities. The proven automatic control
of the extruder output or the line speed
provides optimum return on investments
through material consumption savings.
A highlight of Sikora´s future-oriented
product development is the innovative
X-Ray 2000 series. The success of the
X-Ray 2000 derives from Sikora’s X-ray
experience in online measurements of the
wall thickness, diameter, eccentricity and
ovality without any time delay during the
production process.
Start-up scrap is minimized, material
consumption is optimized and line
productivity is increased dramatically. The
design principle of the X-Ray 2000 is based
on the latest X-ray technology working
without any moving parts. X-Ray 2000 is
available for diameters from 30-270mm.

‘World first’ handheld metal
weight calculator
MetaliCal Inc, Canada, has introduced
what is claimed to be the world’s first
dedicated handheld electronic calculator
for calculating the weight of steel and
metal profiles including tube and pipe. The
company has also introduced MetaliCal
Weight & Cost Calculation software for
PCs, Palms and Pocket PCs (PDAs).
The MetaliCal MWC (Metal Weight
Calculator) calculates the theoretical weight
of different profiles of steel, aluminium,
copper and brass. By keying in the
dimensions of a desired profile, the MWC
will provide the accurate weight. It also
contains a database of steel profiles with
weight/dimensions of long profiles.
The MWC has revolutionized the methods
previously used for weight calculation
by replacing sliding cards and reference
printouts because of its compact size, wide
coverage, accuracy, and convenience.
MetaliCal software – available for PCs,
Palms and Pocket PCs – is an innovative
solution that enables the user to calculate
the weight and cost of 50 different profiles
and shapes of 58 different metals. The
software covers all known shapes and
sizes produced by the industry.
Weight can be established by inputting
the dimensions. The dimension units
are flexible and can be customized in
metric, imperial or a combination of both.
The weight unit can also be displayed in
kilograms, pounds or metric tons.
The cost function enables the user to
calculate cost for stock or requirement in
local and foreign currencies.

with a character height of 3mm.
The HP1PN can be used
with hoses up to a maximum
diameter of 2", and is supplied
with a double control system, in
order to ensure operator safety.
The marker can also be
equipped with an optional
pneumatic pedal and
progressive counter.
