REA Elektronik, Germany,
manufactures non-contact coding
and marking equipment for
industrial applications.
The company’s versatile printers
can be used for printing on many
products and surfaces, and
have proven to be reliable in the
toughest industries, such as steel.
The company will be presenting
its coding and marking systems at
the EuroBLECH show in Hanover,
including the REA-JET ST spray technology marking system, which is designed
to apply all types of lacquer, inks, adhesives, lubricating greases, resins and
mould release agents.
REA states that its customers have very special requirements in terms of short
drying time, as well as clear visibility and legibility of the actual mark on oily,
greasy, damp, absorbent and hot or dirty surface areas.
Applications for the REA-JET ST spray mark system include the marking of
accepted or rejected production parts after quality inspection; marking of
cutting, bending and folding-edges; application of contrast mirrors or dot
marking of electrical boards or shock absorber springs. The automatic REA-
JET spray mark systems are easy to use and have low maintenance costs, and
provide repeatability of a high quality mark in every mounting direction.
The compact design allows for trouble-free integration into an existing
production environment. The size and saturation of the mark can be adapted to
the user’s specifications by use of a simple adjustment procedure, and several
spray mark heads can be combined to form a spray mark block.

Acciaitubi SpA – Italy
As part of its ongoing strategic
investment programme, tubular wheel
company Interpipe has launched a
project to build a pipe coating line
based at Interpipe NTRP.
The planned production capacity of
the line is 250,000 tons of pipes per
year, and it will be the first of its size in
Ukraine.
The process of ultraviolet polymerisation
will be used to coat the pipes, and will
take less than two seconds to dry. The
new coating will protect the pipes from
corrosion for a long-term period – a key
factor when the product is being kept
and transported. The new coating is also
environmentally friendly, as it contains no
harmful substances. Aleksey Slyusarev,
Interpipe director of production and
investments, commented, “This new
equipment brings together the best
combination of ecological sustainability
and functionality. On the one hand it is
environmentally safe for our workers and
on the other, it is a great opportunity to
coat different pipe types, and improve the
commodity properties and performance
of our products.”
