Die casting metal helps to produce sharply defined
shapes with textured or smooth surfaces. This unique process is widely used in
the metalworking industry to manufacture mass produced commercial, consumer,
and industrial products. You can manufacture parts ranging from toys to
automobile parts to faucets.
Die Casting Process
In the die casting process, the molten metal is injected under high pressure into the die or the steel mold. Die casting machines are rated in terms of tonnage which is the amount of pressure that can be exerted on the material. The machines typically range from 40 tons to 4000 tons.

Advantages of Die-casting
·
Die-casting is an economical and efficient process that provides a wide
range of shapes.
·
Die-casting is a fast process.
·
The parts produced are dimensionally uniform.
Pressure die casting (Aluminum alloy)
In the pressure die casting process
the metal is forced into a high grade steel tool at high speed and pressure.
The casting temperature is roughly 700°C when casting aluminum and 650°C when
casting magnesium. The use of vacuum casting technique is a must in order to
achieve superior quality for extremely light and thin walled components.
Pressure die casting is a
competitive casting method when the components are needed at high volumes or
when better tolerances and surface finish are required than can be achieved by
gravity die casting. The need for machining is very low due to the close
casting tolerances. Heat treatment of pressure die casting is not possible but
due to the high rate of solidification the mechanical properties are good. The
tooling costs are considerably higher than for gravity die casting.
Important applications are
found in the components for mobile telephone base stations and certain mobile
telephone applications. The more important reasons for using light metal
casting are low weight, mechanical strength, stiffness and electrical
properties. Other applications are e.g. components for the power transmission
line in the vehicle industry and electronics industry.
