Hot Chamber Die Casting:.
This method involves immersing the injection mechanism (including the plunger and gooseneck) in the molten metal.
It is typically used for metals with low melting points to avoid excessive wear and tear on the injection components.
Suitable Alloys:
Zinc and Zinc Alloys: Commonly used due to their low melting points and suitability for hot chamber processes.
Magnesium Alloys: Sometimes used, though less common than zinc.
Certain Low-Melting-Point Lead and Tin Alloys: It Can also be used in hot chamber die casting.
Unsuitable Alloys:
Ferrous Alloys (Iron and Steel) : These have high melting points and are not suitable for hot chamber die casting because the molten metal would damage the injection system.
High Melting Point Non-Ferrous Alloys (e.g. , Aluminum and Brass): These are also not typically cast using hot chamber machines because of their higher melting points, which would degrade the machinery.
In contrast, cold chamber dies casting is used for non-ferrous alloys with higher melting points, like aluminum and copper alloys. This process involves pouring molten metal into a cold chamber where it is then injected into the die.

Ferrous alloys have high melting point, for that die has to be made of high melting point than ferrous alloys and it costs high. So, generally ferrous alloys are sand casted.

Die casting is a process in which two separate molds are used to cast a product. In hot chamber die casting, it uses low melting point material.

In hot chamber die casting, the furnace is an integral part of the casting system and it is especially used for non-ferrous, low melting point materials.
