Are you looking for plastic blow molding machines ? If so, you came to the
right place.
Our Mission
To design and build high quality plastic blow molding machines combined with
low cost and good service.
- Design
- Safety and reliability features
- Components
- Service
Using 25 years in the blow molding business, Sheen 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 so as to facilitate flash
material elimination and better product quality. The arm system clamping
unit is connected to a vertically moving slide so 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 piston 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.
back
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.
