1.	Which of the following types of cooling is used for the cooling of top and bottom dies in the low-pressure die casting?(a) Water cooling(b) Liquid nitrogen cooling(c) Cooling with fins(d) Air jets coolingI have been asked this question during an interview.I would like to ask this question from Low Pressure Die Casting in division Special Casting Techniques of Casting-Forming-Welding I
Answer» Right choice is (d) Air jets cooling Easy EXPLANATION: The cooling RATE can affect the quality of the casting, so care should be taken to see that the casting is properly COOLED before ejecting from the DIE. For the proper cooling of the top and bottom dies of the casting system, air jets are used which circulated through the dies and takes AWAY the heat.
