1.	The residual molten metal cannot flow back to the crucible and it remains in the riser tube.(a) True(b) FalseThis question was addressed to me in examination.The origin of the question is Low Pressure Die Casting topic in chapter Special Casting Techniques of Casting-Forming-Welding I
Answer» Correct answer is (b) False The best explanation: When the mould cavity is FILLED with molten metal, the pressure in the crucible is removed. This ALLOWS the molten metal to flow back to the crucible through the tube. Then after solidification, the sides die opens and the TOP die is raised vertically. And the casting moves with the top die and ejected onto a TRANSFER tray.
