There are many
manufacturing companies which rely on Die casting processes. The
main benefit which the industries get is that they can easily get high volume
metal components. The manufacturing industry like auto, aerospace and power
tools industries rely on various Die casting process. Pressure Die casting is one of the process. The main advantage of using this type
of process is economical, as it has lower cost compare to other process, also
castings with this type of process has a good surface finish.
Type of Pressure die casting process are:
- High Pressure Die Casting
- Low Pressure Die Casting
- High Pressure Die Casting

High
Pressure Die Casting
High pressure die casting is the process where identical
metal parts are injected in molten metal under pressure into a metal die. This
process is repetitive and requires complex machinery. This type of casting is
best when there is high production rates. It provides the best surface finish.

High Pressure die casting includes:
1. Hot chamber die casting Process

| Hot Chamber Die Casting Process |
2. Cold-Chamber Die Casting Process
Cold chamber die casting process is also in the same lines
when compared to hot chamber die casting process. This process is ideal to be
used with the aluminium metal which has the high melting point. For the metals
that are prone to be corrosive for hot chamber die casting process, cold
chamber can be a good alternative. In this process the melted metal is
automatically- or hand-ladled into the injection system. This eliminates the
necessity for the injection mechanism to be immersed in the molten metal bath.

• Low Pressure Die Casting Process
Low pressure die casting is best suited for aluminium metals which are symmetric
around the axis of rotation. In this process the metal is introduced in the
chill mold. With the help of Gas pressure the metal is hold in the die till it
gets solidifies. Production rates are not as good as compared to the high
pressure.

| Low Pressure Die Casting Process |
There are various Application where Pressure Die Casting can be implemented, some of them are:
- Automotive parts like wheels, blocks, cylinder heads, manifolds etc.
- Aerospace castings.
- Electric motor housings.
- Kitchen ware such as pressure cooker.
- Cabinets for the electronics industry.
- General hardware appliances, pump parts, plumbing parts.
