EXTRUSION
BLOW MOLDING MACHINES
Using 25 years in the blow molding business, Our machines
are designed
this machine to overcome the shortages in other designs and to perfectly suit
the user. Designed to last longer, our extrusion blow molding machines offer
high efficiency, reliability and productivity as well as process capability.
Clamping
 |
The clamping unit is specially
designed as to facilitate flash
material elimination and better product quality. |
 |
The arm system clamping unit
is connected to a vertically moving slide as to ensure equal
distribution of force over the mold pallet as well assuring complete
transmission of clamping cylinder force to the mold surface. |
 |
All bushings are made from especially cast material connected with
lubricators. All movement parts are made of hard chrome |
 |
Clamping
stroke is positioned by electrically operated transducer so as to give
accurate mold positioning and to activate braking just before the mold
closes to give smooth mold closing. |
Extrusion
 |
Our extrusion unit is driven by a Siemens AC motor
controlled by a Siemens inverter connected to the machine main system giving the
machine a great rotational speed range. |
 |
It is more efficient since there is no
loss in a hydraulic pump or a hydraulic motor, thus saving energy, especially
with the new energy saving motors (EFF2). |
 |
More over there is the high precision
sound proof Zambello Gearbox that assures smooth machine running. |
 |
Special attention was paid to the screw profile so as to
give maximum extrusion output with best performance. All extruder component
materials are of high quality life guaranteed steel. |
Hydraulic Unit
 |
Variable pump with pressure compensator
commanded by an AC motor guaranties best electrical
consumption and noise reduction. |
 |
Accumulator connected to system to compensate circuit
pressure. |
 |
Heat exchanger connected to the system giving best
operating temperatures. |
 |
Oil level and maximum pressure are constantly monitored.
|
 |
The system is connected to very precise filters as to
protect hydraulic components |
Blowing
 |
The Pneumatic circuit was carefully designed using the best
pneumatic
antirust components. |
 |
Blow pin is designed to give smooth air flow thus giving
best product surface. |
 |
All critical machine variables are monitored all the time
as to ensure reliable
operation and long components life. |
 |
Oil level and temperature are
monitored to safe guard the pump. |
 |
Hydraulic circuit pressures are
monitored for efficient and reliable operation |
 |
Air pressure is monitored to
ensure that the machine doesn't produce faulty products |
 |
Special protection is for the
screw motor to protect the motor and the gearbox. The machine Software also
ensures only correct operation of the screw. |
Human machine interface
 |
The design had the principle of
ease of use in mind. |
 |
A Siemens operator panel (LCD)
is used to set all machine parameters. |
 |
Push buttons and a selector are used to start and stop the machine for easy
operation. |
 |
The machine also stores product
(mould) parameters (recipes) to
minimize setting time and to help in repeatability. The machine can store up
to 100 recipes. |
 |
The software also has several
levels of password to protect the machine settings from being accidentally
altered. |
