Get to Know the Working of Die Casting and Machining Process

Machining and die casting are both popular and effective processes applied for industrial purposes. How will you know which process is suitable for your project and which isn’t? So, let’s understand how each one works independently and together.

Die casting mechanism

Metals like zinc, copper, and aluminium is melted. Molten is injected in a steel mould or die, which is in the shape of part you desire to produce. After the molten is filled in the die, it is set aside for cooling. The metal solidifies into the desired part shape, which is removed. Precision casting of the part can help perfect assembling in your product line.

CNC Machining

CNC or Computerised Numeric Control is a technique, which maximises machining efficiency via automation of process. You can think machining to be similar to sculpting with metal. The CNC is programmed to cut its way in the metal that you get the necessary part for your project.

Hybrid technique – Machining or die casting

You can use both techniques together to enhance the efficiency in your product line. Machining can be applied on die casting part, so as to generate tight tolerances or build features on parts, which cannot be die casted. Machining can be applied to make die itself to be employed in die casting process.

Which is better?

CNC machining is great for creating parts in low volume, as you save on the tooling cost. Die casting is better for high volume reliable parts. In addition, for parts having plenty of surface details you can choose die casting instead of having them machined later in the finishing process.

Leftover scrap is little in dies casting but in machining process, you will see plenty of scrap metal lying around, at the end of process.
