Advantages of Die Casting
of die casting using pressure injection can be traced to mid 1800. The
components that were used in the initial stages were tin and lead but their use
tapered off with the introduction of alloys of zinc and alloys of aluminum. The process
has evolved over the years from the low pressure injection techniques to the
casting dies at pressures that can reach as high as 4500 psi. The processes are
capable of creating high quality products that have excellent surface finishing.
The die casting process
is an economical yet effective process of creating a broad range of shapes. It
is considered superior to other manufacturing technique and is considered
durable and aesthetic, merging seamlessly with the other parts of the machinery
of which it is a component. Die casting has many advantages and primary among
them is its ability to deliver complex shapes with high levels of tolerance
than any other mass production methods. Identical castings can be mass produced
in thousands before you are required to add any new die casting tools.
pressure die casting is a manufacturing process in which the aluminum in its
molten form is injected with a die casting machine under extreme force, speed
and pressure into a steel die or mold to create parts of the desired shape and design. The rating of die casting machines is in clamping tons universally.
This rating reflects the amount of pressure exerted on the die. The size of the
machine ranges from 400 to 4000 tons.
many benefits of using die casting process over others. Die casting produces
parts with thinner walls, closer limits of dimension and it is possible to
speed up the process. Labor and finishing costs are the lowest with die
casting. Complex shapes with closer tolerances can be easily achieved with this
process. Unlike forging process, you can cast coring in products created
through this process.
impossible to achieve from bar or tubular stock can be easily achieved with die
casting. The number of operation processes is less, leading to lower wastage of
Die casting is used when you need parts that are dimensionally stable and durable. They are heat resistant and maintain good tolerance levels which are crucial pre-requisites for any good machinery parts. They are stronger and lighter than parts made by other casting methods. They do not have parts that are welded or bolted together, thereby immensely enhancing their efficiency. Another advantage is the multiple finishing that you can achieve with die casting. The surfaces can either be smooth or textured providing ease of application and use.
