DDSJ300X2 Double Layers EBM(i.e.: Extrusion Blow Molding Machine) 
DDSJ300X2 is 2 layers EBM with acumulator created by DADAU. 
To produce 200L or 220L chemical drums Double layers & 2 colors &Twin L-ring or Single L-ring 
For example such kind of 220L barrelWeight8.5-10.5kg/pcs Productivityover 20pcs/hour 
2 layers are perfectly even from the slicing, nice-looking !Falling resistance is great from the dropping testing, quality visible! 
IKV Structurer AdoptedHigh output, Nice Plasticizing quality!
Double layer AccumulatorNitriding Hardness is above HV900
Four-bar Structurer for the Clamping Unit
Servo Control of the Mold Opening&Closing Stable & Fast Operation, High Clamping Pressure
A ratchet wrench is enough to move the clamping unit 
Big space between the upper guide pillars,Easy for lifting the mold from its top.
The electric system is controlled by OMRON PLC64 points axial wall thickness control system
Rich content in touch screen display Curve Set, Operation Data Set, Fault Alarm etc. Full Screen Display.
The main oil tank and servo oil tanks are separated, reducing the oil change frequency
The servo cylinder hydraulic system adoptsunloading relief valve and servo valve of Shanghai 704 Research Institute (or Moog)
