Moulding industry is growing steadily and the demand
on the moulded parts quality is increasing day by day. The
requirements are always challenging and needs expert
solutions. In order to meet the required quality stand-
ards, the moulding shop should have Injection Moulding
Machines that are versatile.
The moulding machine is the single biggest investment
in a moulding shop that naturally gets focus. In the
changing business environment the moulder who
moulds commodity plastics today, may have to mould
high end, precise engineering plastics tomorrow.
In addition to the above, the dynamic market situation
forces the moulder to be globally competitive to stay in
the market without compromising the part quality. The
cost of the moulded part is getting reduced day by day,
hence the moulder needs a really Versatile machine
which is also expandable, as and when the need arises.
The machine should be
CLAMPING SYSTEM
- Strong and fast
BENIFITS OF FIVE POINT
TWIN TOGGLE CLAMPING
> The computer-optimised 5-point twin toggle
clamping system ensures uniform force distribution.
The locking force is made available at two levels
thereby ensuring very low mould edge pressure,
consequently enhancing the mould life.
> There is an effective force reserve when maximum
locking is reached avoiding mould breathing and
flashing.
> Computer - optimised braking and acceleration
profiles provide sensitive control of the high-speed
movements.
> Moving platen is supported on the base by accurately
machined roller bearings. The weight of moving half
and the platen is transferred to the rigid base,
resulting in less strain on tie bars and thus eliminate
potential problems when running heavier moulds.

3. HYDRAULIC SYSTEM
Closed loop SYDFEE pump with on board Electronics
In typical injection moulding cycle, almost 14 different
operations take place sequentially or simultaneously,
each demanding different oil flow rate and pressure.
Further, this cycle has to be repeated time, year after year.
To achieve this demanding requirement consistently the
machine hydraulics has to be top-class and long-term
consistent without for frequent attention. Simply the
hydraulics should be precise, obedient and trouble free.
The hydraulic heart of the De Tech series machines is an
electronically controlled close loop variable displacement
pump (SYDFEE). The SYDFEE pump provides fast pressure
and extremely dynamic flow control as well as balanced
machine movements at high reproducibility and
consistency. This allows the operator to set the pressure /
flow characteristics as required - with the dynamics and
precision of servo valves.
The command signals of pressure and flow from the
controls are compared by the integrated electronic card
with the actual values of pressure and flow via the
sensors in the system and constantly adjusted to adhere
to the requirements. This is different from conventional
flow and pressure control methodologies, which use a
metering throttle in the main flow of the pump for
sensing the load. Of particular advantage, the SYDFEE
pump minimises energy consumption since the pump
supplies pressure and flow always according to the actual
demand, i.e. without producing over - capacity.
INJECTION SYSTEM
Precise and consistent
Melt quality is critical to part quality. The well-designed
screw geometry with high compression ratio is optimally
suited for a wide range of thermoplastics. With the
excellent melt homogeneity these machines offer lesser
cooling times.
The injection process has the maximum impact on part
quality. This machine has well defined injection organisa-
tion clearly separating speed control from pressure
control phase. In the speed control phase, the focus is on
injection speed with respect to position and in the
pressure control phase, pressure with respect to time is
important. This well laid out control of injection process
is easy to understand and implement during mould
optimisation. Profiling the process in six independent
stages of speed and hold on pressure with ultra high
speed LNC5 control makes moulding of extremely critical
component a child’s play.
Robust construction of injection
unit with a rigid twin cylinder
design maintains accurate
nozzle position.
