Extrusion Blow Moulding Machines
Extrusion Blow Moulding Machines
Allied Solutions (I) Pvt. Ltd. offers Extrusion Blow Moulding Machines. Advantages of blow moulding over rotational moulding:
- Blown molded 500 liter barrel has weight 9 – 11 Kg per container as against 14 – 14.2 Kg of rotational moulding (Saving of raw material to a tune of 40 % possible)
- Production capacity of 28 nos of barrel using blow moulding machines is possible against 4 to 8 barrel using rotational moulding
- Roto moulded barrel cracks if dropped from height but blow moulded barrel passes the drop test
- Blow moulded container can have 2 layer structure integrated to impart special properties as needed
- Blow moulding is highly energy efficient. Roto moulding is power intensive
- Material handling is simple in blow molding process as against pulverizing of granules required in roto moulding
- Space required for blow moulding machines is lesser compared to rotational moulding
Product & Technology News
- Extruder: The extruder has grooved feed section and special mixingPlastic Drum element to facilitate processing of HMWHDPE producing homogeneous melt at low temperature. It can process HMWHDPE having HLMI as low as 8.
- Extruder Drive: Helical speed reducer with hardened and ground gears ensure high efficiency (0.96 typically) and help cut energy costs.
- Accumulator head: Accumulator head features streamlined melt flow that eliminates problems due to weak weld lines on parison. It is of first-in first-out design to prevent thermal damage of melt.
- Total machine control: Besides parison programming, machine sequence control and temperature control are effected by the PLC.
- Blow unit: Bottom blow unit is of simple design. Parison stretching movement is by pneumatic cylinder with positive mechanical stops.
