What is die casting? Answer: It is a process which produces engineered metal parts by forcing molten metal under high pressure into steel molds. These molds, called dies, can be sharply made, with smooth surfaces, and are suitable for a wide range of serviceable and attractive finishes.
The process of die casting is not cheap. Therefore, the products need to be of high volume and be mass-produced. Such products can be found in lots of commercial, consumer and industrial devices. They may range from automobiles to toys. The components may be as complex as a connector housing or as simple as a sink faucet.
The earliest products of die casting by pressure injection occurred in the mid-1800s, with a patent being given to Sturges in 1849. This machine was manually operated. The process was limited to printer’s type only. Later, the development of other shapes began to increase. Also, parts for phonographs and cash registers began to be mass produced.
The earliest die casting metals were Tin and Lead. Their use began to dip with the introduction of Aluminum and Zinc. Copper and Magnesium alloys followed quickly.
The casting process has today changed. From low-pressure injection methods it is now high-pressure casting, with pressures up-to 4,500 pounds per square inch. High integrity, near net-shape castings with superb surface finishes can now be produced.
The die casting method is expanding and its applications are spreading to almost every recognized market. Now, products can be made in a variety of shapes, sizes with wall thicknesses that are durable and strong.
Products made from die casting have a long service life and can be made to complement the visual appeal of the neighboring parts.
One great advantage of die casting is that it produces components at high speeds. These are dimensionally stable and durable, and are also heat resistant.
Die cast parts are more powerful than plastic moldings of the same dimensions. They are stronger and lighter than those from other casting methods.
The two notable advantages of die casting are:
1. Superb dimensional precision (dependent on casting material, but typically 0.1mm for the first 2.5cm (0.005inch for the first inch) and 0.02mm for each additional centimeter (0.002inch for each additional inch).
2. Smooth cast surfaces (Ra 1–2.5 micrometers or 0.04–0.10 thou rms).
Several metal alloys such as Aluminum, Magnesium, Zinc, Copper, Lead and Tin are available for die casting. Each of these offer particular advantages. The Aluminum alloy is light, while having high dimensional stability for difficult shapes and thin walls. It has good corrosion resistance, and high thermal and electrical conductivity. This alloy is strong even at high temperatures.
Aluminum Die Casting Products are present in LCD TVs, cash registers, screen monitors, automobiles, communication base equipment, heat sinks, bicycle brakes, telecommunication equipment, lotto machine monitor screens, printers, etc.
