If you want to know more about die casting, this article will give you some great help. Die casting is a popular method which has been used by manufacturers in various industries. The casting materials were first manufactured in 1838 and since then they have become really popular around the world. The below mentioned article will offer you complete information on casting. Make sure you pay proper attention towards the information given below.

Mold and Die Casting Types

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; namely single cavity, multiple cavity, unit die and combinations die.

Single cavity is made to produce a component. And you can use the multiple cavity die to create lots 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. You can product smooth and accurate castings by the use of high pressure and speed. 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.

Processes of Die Casting

The process 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 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.

Die casting 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 can 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 casting tools.

High pressure die is a manufacturing process in which the aluminum in its molten form is injected with a casting machine under extreme force, speed and pressure into a steel or mold to create parts of the desired shape and design. The rating of 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.
