1.	In hot chamber die casting processes, downward motion of plunger in the gooseneck leads to injection of molten metal into the cavity with high pressure.(a) True(b) FalseThe question was asked in an interview for internship.My question is based upon Die Casting topic in chapter Special Casting Techniques of Casting-Forming-Welding I
Answer» CORRECT ANSWER is (a) True The best I can EXPLAIN: In the gooseneck, the highest position of the PLUNGER facilitates the filling of the gooseneck by the liquid metal. Then the plunger starts moving down to force the metal in the gooseneck to be injected into the die cavity. The metal is then HELD at the same temperature till it is solidified.
