Die Casting Machines — Cold Chamber Configuration In a cold chamber die casting machine, which of the following statements is correct regarding the melting pot and machine layout?

Introduction / Context:
Die casting machines are categorized as hot chamber and cold chamber based on where the injection system is located relative to the molten metal. This choice affects alloy compatibility, productivity, and equipment design.

Given Data / Assumptions:

• Materials: aluminum, magnesium, zinc, copper-base alloys.
• Focus: cold chamber machines (commonly for aluminum and magnesium).
• Key element: location of melting/holding furnace.

Concept / Approach:
In cold chamber machines, the melting pot or holding furnace is separate. Molten metal is ladled (manually or automatically) into the shot sleeve for each cycle. This avoids immersing the injection components in corrosive or high-melting-temperature alloys, unlike hot chamber machines where the injection mechanism is submerged in the melt.

Step-by-Step Solution:
Identify machine type: cold chamber.Recall defining feature: separate melting/holding furnace; metal is transferred to the shot sleeve.Exclude hot chamber traits (integral pot).Confirm correct statement is Option A.

Verification / Alternative check:
Aluminum die casting cells show external furnaces ladling into horizontal shot sleeves.

Why Other Options Are Wrong:
Integral pot describes hot chamber machines.“Any location” ignores the functional requirement for safe, controlled transfer.Low temperature/pressure only is incorrect; cold chamber often uses high injection pressures.

Common Pitfalls:
Confusing cold chamber (ladle feed) with hot chamber (gooseneck) systems.

Final Answer:
melting pot is separate from the machine
