There are several effective processes for producing metal parts, but two of the most popular industrial purposes and die casting and machining. But how would you know when dying cast and when machining is called for? Here are some basic reasons why you might choose to die casting or machining and how these two processes would work together.

How does Die cast work?

In the Die Casting process, your metal, often alloys of metal such as aluminum, copper, or zinc is melted and is injected in a steel die, or mold, in the shape of the part you would wish to make. Once the metal is filled with the die, you cool it down so the metal hardens into the desired shape. You can complete the part and do any required assembly.

How does the CNC machining work?

The CNC machining means Computer numerical control, and it’s a way to maximize the efficiency of the machining by automating the process. The CNC robot is programmed which then cuts away the metal until what is left is the desired part.

Die Casting or CNC machining?

So, which one of them should you choose? The important thing to notice is that Die casting and machining can sometimes work together to optimize the effectiveness of the product line.

You can use the CNC machining on die-cast to produce tighter tolerances or create a feature on the one part that cannot die-casted, and you even can use machining to make the die itself which will be used for the Die casting.

Another consideration when it comes to the comparison of CNC machining vs. the Die casting is a waste. With the die casting, you use all the metal involved for the part, while on the other hand there is a lot of scraps left when your machine the metal, you can recycle the metal of course. But when you are machining part or working with a precision die casting manufacturer, make sure that there is a recycling mechanism in the place.

If you are seeking a mass production of a high volume of durable, and consistent part affordably, die casting in the metal such as aluminum or related alloy is the way you go to. If you have a small runner on complex parts, or you work on large or oddly shaped parts, the CNC machining would be effective for you.
