In a cold chamber die casting machine Melting pot is separate from the machine
In Cold-Chamber Die Casting. Cold-chamber die casting is ideal for metals such as aluminum which have a high melting point. During this process, metal is liquefied in a furnace at extremely high temperatures and then ladled into a cold chamber to be injected into the die.

Answer is:
true centrifugal casting
Explanation:
Cast iron and steel pipes are produced by True centrifugal casting.
True Centrifugal Casting is t he manufacturing process of centrifugal casting is a metal casting technique, that uses the forces generated by centripetal acceleration to distribute the molten material in the mold.
Answer is:
The casting produced by centrifugal casting method have open and coarse grained structure
Explanation:
Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process.
Answer is:
non-ferrous alloys with low melting temperature are casted
Explanation:
In a hot chamber die casting machine Nonferrous alloys with low melting temperature are casted
In Hot Chamber Die Casting. Hot chamber machinery contains the alloy melting pot as part of the machine itself and uses a gooseneck to inject material from the pot into the die.
materials used in hot chamber die casting are zinc, lead and magnesium alloys.
Answer is:
no core is used
Explanation:
Centrifugal casting is a process that delivers components of high material soundness. . By spinning a mold while molten metal is poured into it, centrifugal force acts to distribute the molten metal in the mold at pressures approaching 100 times the force of gravity.
