How to Design for Die Casting?

Die casting is a process where molten metal is injected into a mould under high pressure. It is used to produce parts with complex shapes that would be difficult or impossible to machine using traditional methods. Hence the importance of having a good design for your die casting projects.

Designing perfect die cast parts is about taking into account the design of the die, the type of metal being used, the production process, and the application of the final product. In other words, it’s about ensuring that every element comes together to create a functional, durable, and aesthetically pleasing piece.

In order to get the most out of die casting, designers need to follow some basic tips.

1. Fillets and radii

2. Wall thickness

3. Ribs and external corners

4. Windows and holes

5. Post machine features

6. Parting lines

7. Surface finishing grades for die casting
   
   

Design for manufacturability

Optimizing your component design to take advantage of the die casting process is the key to seeing a return on your investment. Whether your project is best suited for conventional die casting, multi-slide die casting, or injected metal assembly, it’s best to design your component with the production process in mind. In other words, engineers should approach each project with the intent of designing for optimal manufacturability.

Design for manufacturing (DFM) is a core methodology that ensures that die cast parts perform to specification and reduce the need for secondary operations. Considering that these operations can often represent as much as 80% of the component cost, it’s important to minimize them during the design stage.
