4. PRE-EXPANDER
The process for the production of an EPS
block starts from an efficiently working preexpansion system. The new
TECNODINAMICA batch pre-expanders ,
fully automatic, have been designed to
improve the uniformity of the pre-expanded
foam material and to reduce the cycle
times. Our aim is to get a most advanced
process of treatment of expanded beads
thus obtaining higher uniformity and
density of raw material at each cycle.
The TECNODINAMICA batch pre-expanders
allow to get the required density without

any waste of material and to reach very
low densities by means of one single
expansion. Every single cycle of expansion
is monitored by an automatic density
control device which guarantees the
absolute repeatability of the cycles.
The standard configuration of the
TECNODINAMICA batch pre-expanders
includes: pre-expander with electronic
control-board, PC and touch-screen,
electronic load-cell of feeding material, raw
material feeder, fluidized bed-dryer,

6. BLOCK MOULDERS
Our vertical block moulders are designed
for the automatic production of 'EPS'
Expanded Polystyrene blocks. The moulds
can produce blocks of 100% raw EPS
material, at a density range from min. 8
gr/ltr to max. 60 gr/ltr or blocks with a
variable content of recycled EPS.
The complete range includes models with
fixed or variable depths and heights and
different features according to the final
SOFTWARE
This software enables control of the block
moulder and all the parts connected to it, such
as for example the vacuum plant, loading silos,
block weighing and unloading devices, etc.
Using names and passwords, customised for
the various users, the programme defines the
level of access to the various operations in
order to simplify work during normal production
and make the greatest amount of information
accessible during control and setting
procedures.
The multiple windows enable the production of
EPS blocks to be managed in the best way
possible, controlling pressure, reaction and
temperature values of the material in real-time
and organising all the timings and working
parameters by means of complete control of
the recipes.
The programme enables sintering to be
controlled by creating process graphs which
chronologically plot the historic file of events
and enable, if necessary, former processing to
be recovered together with the associated data
and diagrams.
A broad configuration allows the machine
parameters to be set in order to perfect the
production of blocks as far as possible under
any conditions and with different qualities of
raw materials.
The supervision programme constantly files
away a calendar of events and diagnostic
messages making access to the information
these contain possible at any time.
A manual control section allows all controls on
the block moulder to be carried out easily and
at the same time interventions to be made
during operation to interrupt or complete the
production of a block.

SOFTWARE
As applications in polystyrene evolve, so the
need to cope with ever faster and more
particular production requirements increases.
Automatic cutting lines are carefully studied
to suit the needs of the user, therefore the
management software also needs to be
customised so that it is simple and at the
same time reliable.
Tecnodinamica create their own programmes
in order to interface the user with cuttingedge and innovative solutions, so they can
easily update customised requests and
facilitate maintenance with specific diagnostic
controls.
There are common features which simplify
the management of lines which are bulky and
complex for the user, for example:
•Storable work cards for repetitive
production;
•Tables for automatically checking regulation
(such as cutting speed, temperature and
wire burning corrections) depending on the
density of the material;
•Programmable block count;
•A broad range of possibilities to configure
technical parameters and flexibility in
enabling parts to optimise performance;
•Specific diagnostics for signal control able
to create an historic file of processing
events for each section of the machine;
•Connection to remote servicing.
A graphic interface allows the operator to
have immediate control over the processes
taking place in the workstations.

fixed or programmable inclination and
automatic wire setting
The computerized models are equipped with
an automatic system to regulate the cutting speed
SOFTWARE
In the case of machines with automatic wire
setting, software control enables the
thicknesses and quantities of sheets to be
obtained to be entered even with mixed sizes.
Cutting parameters such as Speed, Burning and
Temperature are managed automatically
according to the density of the material and can
be varied manually by the operator. The
accuracy of the wire setting guarantees a high
degree of precision in the measurements
obtained.
A system of wire tensioning sensors
automatically regulates the speed with
variations which can be customised.
All the production cards can be stored in the PC
and used subsequently.
The programme enables both parallel and
tapered sheet cuts to be made, cutting Speed
and Temperature to be programmed and these
values to be adjusted at any stage of the
processing.
A diagnostics page enables the operator to have
a detailed overview of the machine state and
possible events (for example: emergency and
thermal protection devices, wire ruptures, etc.).

14. DOWN CUTTERS
Our cross cutters are suitable for squaring
the blocks, preparing them for next processing
on other machines such as slicers, contour cutters
and scooping machines.
The range includes hot wire down cutters
having a working surface built on insulated bars,
cross cutters with belts and automatic wire setting.
All down cutters are equipped with automatic
wire breaking detector.
SOFTWARE
In the case of cross cutters with automatic wire
setting, software control enables dimensions
and the quantity of pieces to be obtained to be
entered, even with mixed sizes. Cutting
parameters such as Speed, Burning and
Temperature are controlled automatically
depending on the density of the material
though it is possible for the operator to modify
these manually.
A diagnostics procedure continually checks the
state of the machine and informs the user of
any events occurring during the processing
cycle. Cutting control is automated through the
use of “material present” photocells which
optimise the speeds and temperatures of block
cutting by switching on the cutting wires when
the block passes and moving the block being
processed at maximum speed during the
loading/unloading stages

SOFTWARE
The design programme enables profiles for the
scooping of boxes or sheets to be created. Movement
sequences with which the tool is associated and the
Speed and Depth required for cutting are to be
entered.
As well as making the design of simple scoops easier,
the software also integrates more complex design
controls which enable designed sequences to be
modified by transforming them using graphic and
mathematical functions.
A table enables the sequences of the project to be
associated with the basic features of the tools, such
as diameter, depth and rotation speed. This enables
speed and cutting precision to be optimised.
The processing programme controls the 3-axial
movement of the cutter, automatically changes over
the tool as envisaged in the design, configuring the
different rotation speeds of the tools and controls the
automatic sheet loading and unloading station
machining process when required.

18. SCOOPING MACHINES
SOFTWARE
TD680E . ELECTRONIC SCOOPING MACHINE
The Project design programme produces the
cutting profiles for scooping machines by
controlling the XY (Vertical) and XZ
(Horizontal) movement planes and the
rotation of the head. The rotation can be
defined as a single rotary movement or
combined with the insertion of horizontal
movements to define a closed perimeter
scoop. The effect produced depends on the
movement and the shape the wire applied
was modelled to.
Simulation enables the regulation of different
speeds during the course plotted thereby
optimising the quality of cutting and
production times.
Specific controls make it easier to produce
the scoop project quickly and enable the
internal hollowing of the movement
perimeters to be studied according to the size
of the scoop wire envisaged.
The processing programme controls the
movements of the 3 axes on the cutter,
automatically inserting the rotation of the
head to produce the closed perimeter scoop.
Adjustable stops enable the initial wire
rotation angle to be defined.
The automatic processing cycle is
electronically controlled by means of a
keypad with wide visual display which
allows profiles to be edited and stored.
The machine is equipped with an
auxiliary motor which also enables
scooping of circular profiles and is
provided with an automatic feeder with
pneumatic loading and clamping of the
pads into position.
