Manufacture of plastic tubes
MAINTOOLS GmbH & Co KG, which is
engaged in the production of extrusion
lines for the manufacture of plastic
pipes, has achieved an important new
development in its business field of
corrugators.
In addition to a compact design, the
high performance corrugators Protos
165 and Protos 270 have a very high
degree of flexibility. Equipped with
a productive capacity of more than
30m per minute and an output rate
of 800kg per hour, multilayer pipes
with a maximum outer diameter of
165mm/270mm are produced, mainly
for the fields of cable protection and
sewage technology.
The decisive factor for these
extremely high production speeds is
the direct, tubeless and completely
wear-and maintenance-free cooling
system. In combination with the further
development of the mould blocks, 50%
higher cooling water flow rates can
be achieved. Besides that, also the
curve-optimised circulation of the mould
blocks as well as the quick-change
system characterises the advantages of
these corrugators. The replacement of a
complete set of mould blocks takes less
than 30 minutes.
Based on the newly developed drive
concept, the Protos 165 does not need
any manual or electrical adjustment of
the mould block clearance. In addition
to the minimisation of the maintenance
costs due to the innovative cooling
system, a significantly lower wear of
machine parts can be reached by the
weight advantage of the mould blocks
as a result of the “Zooming Technology”
of the Corrugator (ie the basic forms
of the mould blocks “grow” or “shrink”
together with the dimensions).
In addition to the manufacture of
corrugators Maintools GmbH & Co
KG is also engaged in the following
business fields: winding pipe systems
for large-scale plastic pipes, extrusion
lines for the production of multi-layer
composite pipes and extrusion lines for
drip irrigation pipes.
