Benefits of die casting: Pressure Die Casting When molten metal is force-pressed highly to form mold cavities, this process is called die casting. The process is basically used to form different desired shapes out from hardened metal. However during these times, an alternative to these types of parts have slowly replaced these metals due to lower costs and light weight. But of course, the effectiveness of hardened and formed metals can never be replaced. The process started in the early days and was done first using the low pressure injection method. But as time passed by with the technology rising, the use of high end, high pressure techniques like two of the most common squeeze casting and semi-solid casting processes have become more effective than the previous method. Before, only tin and lead were involved in this process; but today even copper, alloys and magnesium can already be used and done with the famous high-pressure method.

Moreover, there are four types of dies; namely single cavity, multiple cavity, unit die and combinations die. The first type, single cavity, as the name implies is made to produce a component. The second one, the multiple cavity die, is used to create a number of equal or matching parts. The third type which is the unit die is used to produce various types at the same time. And lastly, the combinations die is used to create a number of varying parts for an assembly. The creation of the die cast products is done under high speed and pressure where the molten metal is injected to the die. With the use of high pressure and speed, smooth and accurate castings can be produced. This pressure exerted on the materials should be maintained until the metal forms and solidifies into the desired shapes. Right after the metal becomes hard, immediately open the die and remove the output product.

When molten metal is force-pressed highly to form mold cavities, this process is called diecasting. The process is basically used to form different desired shapes out from hardenedmetal. However during these times, an alternative to these types of parts have slowlyreplaced these metals due to lower costs and light weight. But of course, the effectiveness ofhardened and formed metals can never be replaced.

Actually, dies are composed of two part molds namely the ejector die and the fixer die.These molds are composed of alloy tool steel. Moreover, there are four types of dies; namelysingle cavity, multiple cavity, unit die and combinations die.

The first type, single cavity, as the name implies is made to produce a component. Thesecond one, the multiple cavity die, is used to create a number of equal or matching parts.The third type which is the unit die is used to produce various types at the same time. Andlastly, the combinations die is used to create a number of varying parts for an assembly.

The creation of the die cast products is done under high speed and pressure where themolten metal is injected to the die. With the use of high pressure and speed, smooth andaccurate castings can be produced. This pressure exerted on the materials should bemaintained until the metal forms and solidifies into the desired shapes. Right after the metalbecomes hard, immediately open the die and remove the output product.

The Benefits and Disadvantages

Just like any other processes, die casting methods have both advantages and disadvantages.The following are outlined below:

Benefits of die casting:• Die casting parts have longer life service, tolerance and accurate dimensions compared toother castings• Process is economical• The mold can be re-used• Can be done through an automated processDisadvantages of die casting:• Initial cost is quite expensive• There is a casting weight preference which is between 30grams• Casting product should be smaller in size than 24 inches or 600mm• The process is only limited to highly elastic metals

Die Casting Automation

As mentioned above as one of the advantages, the process can indeed be fully automated.With the modern enhancements on the process, there are machines which are fabricated toensure consistency in quality. The entire automation process covers the whole die castingprocess including lubrication of metals to pouring metals to the chamber. This auto-processcan be done in two variant methods - the hot chamber and cold chamber methods.
