•   As the sand shooting and squeezing are at the top of the machine, all cylinders are outside which is open which makes maintenance easier.
•   The requirement of sand is not so strict (moisture, sand strength, etc.).
•   Vertical sand shooting uses the gravity force hence lesser air pressure is sufficient.
•   Pattern change is easy since there is no bolt fixing.
•   Pouring gate position is easy to change as it can be done outside of the machine.
•   Horizontal stripping with spring loading makes minimum shift in the mould. Hence after pouring the parting line has very less fins which do not need any grinding.
•   Little sand fall during moulding which is easy to clean.
•   Because of the structure of pins and guide slices, the mismatch is small (precision is good) AMF II, AMF IV - 0.2mm, AMF III - 0.3mm.
•   Pattern plate can be made from wood. Hence the test is easy to take [lesser development time].
•   Depending on the casting shape the thickness of sand can be selected accordingly which can save sand cost.
•   Down sand blowing, the distance is short which is good for filling.
•   The combined sand blowing has five choices, which can be selected according to the type of castings.
•   Pouring cup is removed immediately after squeezing so there is no possibility of falling of loose sand into the mould.
•   Mould thickness can be varied [from 3 to 5 levels] depending upon the type of castings.
•   The whole machine is open structure which is convenient for inspection and maintenance.
