Die Casting Process and Its Advantages

First things first! So let us see what is die casting?

It is a metal casting method that is exemplified by forcing molten metal under high

pressure into a steel mold. Two hardened tool steel dies are used to create the mold

cavity which has been machined into shape and work correspondingly to an

injection mold throughout the action. The metal hardens quickly after the injection

and then the part gets cast out from the mold. Die casting parts are characterized by

their distinct, smooth or textured shells and dimensional regularity.

Basically, die casting make use of steel molds called dies where molten metal is

enforced hooked on with tremendously high-pressure. Die casting is a resourceful

technique that allows for a range of stages of intricacy in manufacturing from steel

sinks to tiny toy cars. At the same time it still maintains complete exactitude to

generate an unblemished end product.

Die Casting Process:

In die casting there are four steps involved and it is a must that each phase is

completed thoroughly before getting on to the next phase As it allows perfection in

the end product. The die worker must be certain that the die casting machine is at

the required temperature. There are several possibilities for it to get wrong if the

die is cold when the molten metal is injected because it will solidify too quickly

without conforming to the correct shape. Heating will take some time according to

the size of the designed cast so only after the die reaches the right temperature the

casting should begin.

The very first step in die casting:

The mold is sprayed with lubricant and then closed. Lubricating helps to regulate

the temperature inside of the die, at the same time it also allows helps in trouble-

free removal of the cast.

In the next step the molten metal is injected into the die and then the metal is

inserted at an enormously high pressure, thereby it allows the metal to conform to

the fixed figure of the die, devoid of the risks of puffiness or air pockets inside the

product.

After that the mold is allowed to cool and thereby the metal gets solidified. It

differs according to the level of the stage. Still the high-pressure is maintained

inside the mold such that metal doesn't change properties. Finally the die opened

and the solid cast removed.

Advantages:

1) Excellent dimensional accuracy;

2) Reduces or eliminates secondary machining operations.

3) Rapid production rates.

4) It has the ability to deliver complex shapes with high levels of tolerance.

5) Identical castings can be mass-produced in thousands before you are required to

add any new casting tools.
