Die casting and CNC machining are two of the most popular industrial processes for producing metal parts. Both of them can be combined for the best possible finish. However, when it comes to choosing one process over the other, there are some important factors to consider. Die casting involves melting metal and injecting it into a steel mould (die casting mould). The metal is then cooled down so that it hardens in the shape of the part. CNC machining, automates the process by using a robot to sculpt the part from the metal. Both of these processes are frequently used to manufacture metal components and fittings for objects that we use every day, such as car and computer parts.

Should choose CNC machining or die casting?

CNC machining is more expensive than die casting, but this depends on the type of parts and level of production. Usually cnc prototyping China is used to create the die, and to add more complex features after a part has been die cast. If you want to compare the separate processes for forming a part, here are several of the major deciding factors--

1) Precision

Die casting can precisely form complicated geometrical shapes, but can sometimes result in surface defects such as burrs or flashes which require machining to clean up. China custom CNC can create finished parts with great precision and tolerance, especially if they are highly customized small parts. However, die casting is still a great choice for creating identical parts when the surface detail can be engraved into the master mould.

2) Production speed

Die casting is much faster than China cnc custom machining and easily repeatable. Even if machining is required post-casting, it will still take far less time than machining a detailed part from a solid block of metal. This speedier production cycle makes die casting more reliable for producing large batches. That said, CNC machining can create a faster lead time when it comes to producing smaller volumes, as long as you have the digital model ready. It can also be faster when need rapid prototyping China. Rapid prototyping manufacturers in China will produce China custom cnc mechanical parts for you as soon as possible.

3) Quantity

If you need to produce a low volume of parts only, cnc rapid prototypeing China has the advantage because it doesn’t require molds costs. On the other hand, when it comes to high volume production, die casting is the better choice for consistent quality and quantity. Die casting is best for durable mass production, while CNC machined parts China is best for small runs of particularly complex or oddly shaped parts.

4) Waste

There is very little scrap metal left after die casting, which makes it more affordable, cnc prototype China can leave a lot more scrap behind when carving away layers of a metal block. If you are concerned about minimising waste, but would prefer to use CNC machining, it is important for a recycling system to be in place in order to reuse the scrap metal.
