Die casting was first invented in the year 1838 which proved to be a major innovation in the printing industry. The first patent was granted in the year 1849 and there was no looking back for this game-changing scientific discovery. Die casting facilitated growth for a lot of consumer goods and day to day material. It not only accelerated the human race but made a lot of goods more affordable to mankind.
What is die metal casting?
Metal casting is a simple process by which a molten metal is forced into a mold cavity under very high pressure. Two tool steel dies are necessary to create a molten cavity. The steel dies are then shaped using a machine. Die castings are prepared using metals such as aluminum, lead, zinc, copper etc. The machine chamber temperature depends on the variety of the metal used. Material like zinc requires a cold chamber die casting.
Why is China zinc die casting preferred?
Out of Magnesium, aluminum, lead, copper, zinc is preferred for die casting due to a number of advantages. For a starter, zinc is the most economical of all the metals available for die casting. Due to its high ductility, it is one of the easiest metals to cast. Zinc has a relatively higher impact strength which promotes the die life to a longer extent. Since zinc can be easily plated, preparing small parts becomes easy for the manufacturer.
What are the main advantages of zinc die casting?
There are many advantages of zinc die casting. The dimensional accuracy of zinc is as good as 0.1 mm. Zinc can be used to produce thinner walls that prove to be extremely beneficial for industrial usage. A smooth cast surface along with a high tensile strength helps to scale the production rate in a short time interval.
Types of die casting:
There are two methods of die casting- hot chamber die casting and cold chamber die casting. Both the methods are segregated by their clamping force. While the first method relies on the molten metal that needs to be fed to the die, the second method is used when a casting alloy becomes difficult to use in the hot chamber.
Industrial application of zinc casting:
There are widespread industrial applications of China zinc die casting moldmaking. From kitchen appliances to bathroom fittings, hair drier to razor, mixer to car sit belt, zinc die castings are used almost everywhere. Perhaps the biggest application of the zinc die casting is that it is used to make zipper- which is used in every sphere of life.
The sustainability factor of Zinc:
Zinc is the 17th most commonly occurring metal that is found in the crust of the earth. Its recyclable nature makes it the most preferred choice among all die casting elements. Post the die casting life cycle a zinc-based material can be recycled to any steel based material. Another important factor that makes zinc the preferred choice is its razor sharp precision without having to use any machine to do so.
