As earlier stated, die
casting is one of the methods of metal casting used to create casts,
which are known as dies in the automobile industry. The molds used
for the die casting methods are reusable. Industries make use of this
method to manufacture different kinds of complex shapes. It is
crucial that the shapes produced are defined, have either or smooth
textures and can be subjected to various finishes, as per
requirement. The method of die casting is used in various industries
ranging from automobile to toys industry. With the help of this
method one can make something as simple as a tap or as complex as a
cylinder block.
The metal to be used for
the die casting method generally belongs to the non-ferrous category,
like aluminium, zinc, copper and so on. Aluminium die casting firm
are not very common, not every aluminium die casting manufacturer
can handle aluminium in its pure form. Other ferrous metal like zinc
has to be added to aluminium, the proportion is very crucial. This
was a brief overview of the die casting method, lets now take a look
at the history of the same.
History of Die Casting
The history of the die
casting goes back to the 18th century. In 1838, the very
first die casting equipment was invented. This equipment was used in
the printing industry for the purpose of producing movable type.
Though equipment was invented in 1838, a patent was rewarded for the
equipment produced in 1849. Sturges was the lucky person who grabbed
the patent, for his invention of the first manually operated casting
print type. Otto Mergenthaler gained popularity for his invention of
the linotype machine in 1885. Version of the same linotype machine is
still widely used in the printing industry. Though die castings are
now used in almost every industry now, in the beginning the
production of castings was limited only to the printing industry. In
the early 19th century, the production of commercial die
casting began.
The metals that were used
for making the castings in the initial stages of production were tin,
lead and their various compositions. After the usage of aluminium and
zinc for the production of the castings, people rejected lead and tin
castings. Since then aluminium casting companies are in full fledge.
The process of die
casting has also changed since. Earlier only the low-pressure
injection method was used, now a days the high-pressure casting
method is widely used. Due to the modern method casting with
excellent surface finishes and high integrity can be produced.
This was about the
history of die casting in a nutshell. Looking at the present usage of
aluminium die castings in the various industries, we are definitely
going to need many more aluminium
die casting companies in the future.
