How to choose the manufacturing process in CNC machining and die casting
For the growing demand, there are many common manufacturing processes and a good choice is beneficial for both suppliers and customers. Die casting vs. CNC machining, what is the difference and which one to choose? Here are some considerations for using the right manufacturing process.
What is CNC machining?
CNC machining (Computer Numerical Control Machining), a cnc precision machining under digital computer control, allows for a variety of special processes and complex surface finishes such as chamfering, non-penetrating pattern or texture engraving, drilling at bends, etc. Even the most demanding and difficult details may be achieved with CNC machining for individual requirements and custom machined parts.
What is die casting and how does it work?
The die casting process involves applying high pressure to molten metal in a mold cavity to create the same shape and surface as the mold. Molten metal, such as aluminum and copper, is injected into the steel mold until it fills the mold and it is cooled down so that the metal will form the desired shape. Some simple stamping and pattern forming work can be performed during the die casting process. It is less expensive than the CNC process, but extremely complex processing cannot be done.
Die Casting vs. CNC Machining - How to choose the right manufacturing process
What is the difference between CNC machining and die casting? When is die casting and when is CNC machining better? To choose the right method, we need to understand the advantages and disadvantages of both technologies, as well as their applications, characteristics.
1, in terms of production volume, CNC machining is more suitable for small batch products, because there is no need for tooling costs. Die casting is the first option to consider for a large number of consistent parts.
2. For part features or details, all surface details can be included in the mold to produce the part directly, saving time significantly. CNC machined parts may require post-processing or secondary machining.
3. In terms of cost and material, most of the material will be used for die casting, with very little scrap. Since CNC machining is a cutting operation, there will be some material debris and residue around the machine that you will need to clean or recycle.
4. CNC machining can produce more complex geometries, oversized or shaped parts and tighter tolerances that are not possible with die casting. Die castings can also be machined by the CNC process to add more functionality.
