Hot Chamber Die Casting: Die Casting is an injection mechanism or Metal Casting process. This process is basically used in die casting machines that use high temperature to immerse hot chamber into molten metal. Most of Die casting machines are usually made by non-ferrous alloys means that which have not been used an appreciable amount of iron. These alloys based on especially aluminium, magnesium, zinc, copper, lead, tin, and pewter. To produce numerous wide range shapes manufacturer use this process which is more reliable and efficient. To understand fully mechanism this process is divided into two parts.
- Hot Chamber Die Casting Process
- Cold Chamber Die Casting Process
Hot Chamber Die Casting Machine Process
Hot Chamber Die Casting process is mainly used for the mixture of zinc, lead, magnesium, all other alloys that having low melting points. The whole process usually Hot Chamber Die Casting Process is mainly used for those metal vessel, cylinders, and flags that do not destroy easily. When low melting points are ejected under heat or pressure then all those metal do not resolve or destroy into metal. Hot Chamber Die Casting Process is also known as “gooseneck”. Basically, it is just like a pool in which molten metal is feed to die.
Components of Hot Chamber Die Casting Machine
In the injection mechanism of Hot Machine which is used to immerse metal parts into molten metal. For this purpose, the furnace is feed from the feeding part of hot Casting Machine which is usually called gooseneck.
The piston moves from lower position to higher position and ports open when die will be closed. This mechanism fills the cylinder with molten metal. The complete process of filling the cylinder with molten metal is done in a chamber which is called Chamber Die Casting.
After that ports will be closed by the plunger. Next full molten metal is feed into the die cavity and takes under pressure until it takes solidified. Then Die will open and plunger will back to its position and casting is ejected.
Cold Chamber Die Casting Machine Process
In contrast hot process, Cold Die Chamber Die Casting Process is usually used for alloys who having high melting points. However, Clod dies casting machines mainly used a mixture of aluminium, brass, copper and all other alloys whose melting points is so high other than low. The top manufacturer used this type of chamber to produce different top designing parts.
Instead of hot die casting machine cold one require the addition of some external equipment’s.
- A furnace that feeds externally
- Ladle which is usually used to feed metal into the machine
The different molten metal which you needed to use dies directly enter into the chamber of the die. Once the metal is added into chamber sufficient pressure. Then using high-pressure molten metal is die and enter into a cylinder with a plunge. As the whole process is working under pressure. Here high pressure requires other than high chamber die to cast machine-like as you the pressure machines work with the Household Products.
As we already mentioned that the die casting process is used most of the top leading manufacturer. The reason behind this is high precision and accuracy. That is why nowadays, both cold, hot die casting process is used as well as multi-casting.
