Die Casting Process
|

|
By George Ure |
The die-casting is a process that is used to produce metal parts by forcing molten metal into reusable steel molds under high pressure. These molds also known as dies are specially designed to produce different shapes of varying complexity with a high level of accuracy and repeatability.
Die casting metal helps to produce sharply defined shapes with textured or smooth surfaces and a variety of attractive finishes. This unique process is widely used in the metalworking industry to manufacture mass produced commercial, consumer, and industrial products. You can manufacture products as small as toys to big automobiles or products as simple as a faucet to complex ones such as connector housing.
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 clamming tons that is equal to the amount of pressure that can be exerted on the die. The machine size ranges from 40 tons to 4000 tons. The machines are differentiated on the basis of the method that is being used to inject molten metal in the mold or die. Die-casting is the fastest technique presently being used to produce non-ferrous metal parts.
Advantages of Die-casting
Die-casting is an economical and efficient process that provides the widest range of shapes and components than any other technique type.
These parts have long life span and can be made to compliment the visual aspects of the surrounding parts.
Die-casting allows the manufacturer the advantage of high-speed production. You do not require any machining and a large number of identical parts can be made before you require any additional tooling.
The parts produced by the die casting process are dimensionally stable as well as durable and maintain close tolerances. They are also heat resistant.
As compared to injection moldings, with the same dimensions the die cast parts are much stronger. The walls are stronger yet lighter as there are no separate parts that are fastened or welded together. The strength of the part comes from the alloy and not from the joining process.
You can get products with multiple finishes that can be finished or easily plated with minimum amount of surface preparation.
The die cast parts have simplified assembly and may be provided with bosses and studs for fastening.
