When molten metal is forced-pressed extremely to form mold cavities, this process is known as die casting. The process is usually used to make different desired shapes out of hardened metal and alloy. Anyway, during these times, a substitute for these kinds of parts has slowly changed these metal due to lower costs and lightweight. But definitely, the effectiveness of hardened and formed metal can never be changed.
The process started in the early days and was performed first using the low force injection technique. But as time passed by with the technology rising, the use of high end, top pressure methods like two of the most general squeeze casting and semi-strong casting processes have become more effective than the previous techniques. Before, only tin and lead were involved in this procedure, but today even alloys, copper and magnesium can already be used and done with the popular high-pressure method.
Dieting casting and mold types
Actually, dies are composed of 2 parts molds namely the fixer die and ejector die. These molds are composed of alloy tool steel. Additional, there are 4 types of dies, multiple cavities, single cavity, combinations die and unit die.
The first type, a single cavity, as the title implies is made to generate a component. The second once, the multiple cavities die, is used to make a number of matching or equal parts. The third type which is the unit die is used to generate various kinds at the same time. And finally, the combinations die and street light housing is used to make a number of varying parts for an assembly.
The creation of the die casting parts is done under top speed and force where the molten metal is injected into the die. With the use of top force and speed, perfect and right castings can be produced. This force exerted on the stuff should be maintained until the metal forms and solidifies into the wanted shapes. Right after the metal becomes hard, fast open the die and get rid of the output product.
Advantages of the die casting process
Just like any other process, die casting techniques have both pros and cons. The following are outlined below:
Advantages of die casting
- Die casting parts like street light housing have longer life service, right dimensions, and tolerance matched to other castings.
- Process is economical
- Can be performed through an automated process
- The mold can be re-used
