Pouring metal at a high rate into a mold can have certain disanvantage.
Are there any disanvantage to pouring it very slowly?

In casting metal alloys, what wound you expect to occur if the metal were agitated aggressively after the molten metal had been in the mold for a sufficient amount of time to form a skin?

Cross sectional area as the round casting. Both pieces are cast under same condation.What is the dirrerent in the solidification times of the two castings?

The mold can be broken safely when the solidfied shell is at least 20mm. Assuming that cylinder cools evenly, how much time must trasnpire after pouring the molten metal before the mold can be broken?

It was stated that the stregth-to-weight ratio of die-cast parts increases with decreasing wall thickness. Explain why?

Why does the die-casting machine have such a large mechanism to close the dies? Explain.
