What is Aluminum Injection Molding Machine (Aluminum Casting Machine)?
Aluminum is a good alloy for die casting due to its high thermal and electrical conductivity, good mechanical properties and corrosion resistance.
In the manufacturing process of the aluminum injection machine, the aluminum is heated until it melts, then the molten metal is poured into steel die-casting molds. Once cool enough, the substance can be removed from the mold and still retain the shape of the inner cavity for use or processing.
What Functions Does Aluminum Injection Molding Machine Have?
Melted metal is forced or poured into steel molds during the manufacturing process known as die casting. Steel molds, also called tools or dies, are custom made for each project. This makes it possible to create each component with precision and consistency.
What is Aluminum Injection Molding?
Die casting alloys made of aluminum are thin and lightweight and have high dimensional stability for parts with complex geometries and thin walls. Aluminum is a good alloy for die casting due to its high thermal and electrical conductivity, good mechanical properties and corrosion resistance. Metals made of low-density aluminum are required for the die casting industry. Cold chamber machines are necessary because the aluminum die casting process provides a durable strength at extremely high temperatures. A furnace is used to melt the molten metal to the required temperature while it is still in an open holding vessel.
Since the normal pumping system would be damaged by high temperatures, the open holding ladle is kept separate from the die casting machine and the molten metal is scooped from the ladle with each casting. More pressure is usually required for cold chamber castings than for hot chamber die castings.
Die Casting is a manufacturing procedure in which the casting is made under external pressure. They can be divided into two types according to the intensity of the pressure used. They are,
- High Pressure Injection
- Low Pressure Injection
In this article, the main differences between high-pressure aluminum injection and low-pressure aluminum injection are discussed.
The most widely used production process in the world is high-pressure aluminum die casting, or HPDC. Currently, high-pressure aluminum die casting is used by about 70% of die casting manufacturers.
High Pressure Injection
Below, we have outlined the high pressure die casting process for aluminum:
- The melting of aluminum alloys takes place in a separate furnace from the die casting machines.
- Then use a manual or robotic arm scoop to transfer the liquid aluminum into the equipment's shot sleeve.
- The molten metal will then be pushed into the mold by the piston with great pressure. Now allow the casting to cool and solidify inside the molds for a predetermined period of time.
- The finished casting should be removed after the mold halves have been separated.
Low Pressure Injection
There are some notable structural differences between a low-pressure aluminum injection molding machine and a high-pressure aluminum die casting apparatus.
Below is a description of the low pressure die casting process for aluminum.
- Aluminum alloy is melted in a tightly sealed furnace. The riser tube connects the mold halves placed on top of the furnace.
- Apply low air pressure from inside the furnace. As a result, the molten aluminum will rise along the tube and fill the mold cavity.
- Keep the air pressure constant until the casting hardens.
- Finally, remove the casting by opening the molds.
