EXTRUSION BLOW MOLDING MACHINES

Machine Specifications

Design

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

bullet

The clamping unit is specially designed as to facilitate flash material elimination and better product quality.

bullet

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.

bullet

 All bushings are made from especially cast material connected with lubricators. All movement parts are made of hard chrome

bullet

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

bullet

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.

bullet

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).

bullet

More over there is the high precision sound proof Zambello Gearbox that assures smooth machine running.

bullet

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

 

bullet

Variable pump with pressure compensator commanded by an AC motor guaranties best electrical consumption and noise reduction.

bullet

Accumulator connected to system to compensate circuit pressure.

bullet

 Heat exchanger connected to the system giving best operating temperatures.

bullet

Oil level and maximum pressure are constantly monitored.

bullet

The system is connected to very precise filters as to protect hydraulic components

 

 

 

Blowing

bullet

The Pneumatic circuit was carefully designed using the best pneumatic antirust components.

bullet

Blow pin is designed to give smooth air flow thus giving best product surface.

 

              

                                                                                                           

Safety and reliability features

bullet

All critical machine variables are monitored all the time as to ensure reliable operation and long components life.

bullet

Oil level and temperature are monitored to safe guard the pump.

bullet

Hydraulic circuit pressures are monitored for efficient and reliable operation

bullet

Air pressure is monitored to ensure that the machine doesn't produce faulty products

bullet

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

 

bullet

The design had the principle of ease of use in mind.

bullet

A Siemens operator panel (LCD) is used to set all machine parameters.

bullet

Push buttons and a selector are used to start and stop the machine for easy operation.

bullet

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.

bullet

The software also has several levels of password to protect the machine settings from being accidentally altered.
