Have you got any information about die casting?

Die casting is the process by which molten metal under high pressure is forced into steel molds so as to create specific shapes after the metal cools. Die casting is used in stainless steel foundry,iron casting foundry,automotive casting manufacturing,precision casting iron and so on.

Dies

According to the North American Die Casting Association (NADCA), dies are the molds into which the molten metal is poured. These molds can create parts as trite as a toy soldier or 'as complex as a connector housing.'

History of die casting:

Die casting is a method of forcing molten metal into a mold called a 'die,' and it was initially used to cast metal parts for industry in the mid-1800s. The metals were originally alloys of tin and lead, but by the 1930s, zinc and aluminum, and magnesium and copper were the standard. Die casting was at first a low pressure process, but by the 21st Century, forces equaling 4,500 pounds per square inch were possible.

Die casting was important to the development of industry and mass production. The first known use of die casting by pressure injection occurred in the 1800s, the NADCA reports. In 1849, die casting was being used almost exclusively to create printing type. Since then, its uses have expanded exponentially.

Modern Uses

Today, the list of products made from die casting is diverse. According to the NADCA, 44 percent of the market for die cast materials is the auto powertrain market. The next highest are miscellaneous items at 10 percent and builder's hardware at 9 percent.

Die Cast vs. Plastic

Die cast parts are stronger than comparable plastic parts of equivalent size and dimension, the NADCA says, and die cast parts are also more conductive to electricity and more temperature resistant.

Fun Fact

There are four types of dies: single cavity dies (to produce a single part), multiple cavity dies (to produce multiple parts at once), unit dies (to produce different parts at the same time) and combination dies (which create multiple parts that fit together).
