die-casting machine


The whole process of operation of die casting machine.

A die casting machine works by injecting molten metal into a die (a two-part tool used to shape the metal), under high pressure and at a high speed.  Once the metal solidifies, the die is opened, and the finished part is ejected.  There are multiple steps in the die casting process for aluminum, zinc, and other alloys.

1) Preparation of the die: The die is first preheated and lubricated to ensure that the molten metal flows smoothly through it.  The two halves of the die are then clamped together.

2) Injection of molten metal: The molten metal is melted and maintained at a specific temperature in a furnace.  A piston then forces the molten metal into a shot chamber, from where it is injected into the die under high pressure.

3) Cooling of the die: After the molten metal is injected into the die, it cools rapidly and solidifies, taking the shape of the die cavity.

4) Opening of the die: The die is opened, and the finished part is ejected from the die cavity by an ejector system.

5) Trimming and finishing: The finished part may require trimming or finishing to remove any excess material or imperfections.

6) Recycling of scrap metal: Any scrap metal that is produced during the process is collected and recycled.
