Explanation: The minimum pressure, which can be applied in a pressure die casting is 70 kg/cm2. Below this pressure at 50 or 60kg/cm2, the process of casting will not take place.

Explanation: The maximum pressure, which can be applied in a pressure die casting is 5000 kg/cm2. For some castings, with lesser hardness, the maximum pressure limit is lesser. If the magnitude of pressure applied exceeds the value of 5000kg/cm2, then the cast may get damaged.

Explanation: Among the following metals, the alloys which are made up of iron are least manufactured using hot chamber die cast method, while all others are widely used.

Explanation: In cold chamber die casting, a decent amount of pressure has to be given. The minimum pressure, which can be applied in a cold chamber die casting is 200 kg/cm2.

Explanation: None.

Explanation: In the process of hot chamber die casting, as soon as the stroke ends, there has to be some part which would remove the cover over the port. In hot chamber die casting, before the end of the stroke, it is the plunger that uncovers the port.

Explanation: Pressure die casting is used for mass production, the reason being, that equipment needed in pressure die casting is not available at low costs. The dies used in this process too are very expensive.

Explanation: Pressure die casting, overall is a very useful process. It is handy when small parts are to be produced. Up to ± 0.076mm of close tolerance, in pressure die casting, making small parts becomes possible.

Explanation: In pressure die casting, it is one of the advantages of this process, that castings which have very small sections too can be casted by it. The section of the casts can be manufactured up to 0.5mm.

Explanation: In pressure die castings, a very high production rate is possible, as it becomes economical for large quantities.
