Why Are Ribs Needed for Die Casting?

Some die cast parts are ornamental only. Others have serious jobs to do once they’re produced – specifically that they will serve as structural part of a greater design. That means that strength and hardness under extreme pressure are essential. Thus, it might be necessary to add design elements that increase the strength of a part that could otherwise only be for show. One way that the strength of die casting components is reinforced is through the use of ribs. Die casting ribs help to increase the strength and soundness of any die cast component, regardless of alloy.

Why ribs for your die casting design?

•          Increase the strength of the component without adding unnecessary thickness to walls of the die cast part
•         Help melted metals to flow more smoothly to parts of the mold that would be otherwise difficult to properly fill
•          Decrease overall product weight while maintaining needed physical properties

Ribs & Initial Die Casting Design Prototypes

Die casting rib design should be incorporated into your mold design at the earliest stages possible. The correct placement of die casting ribs is essential to ensure that your ribs create only advantages for your die cast part. Also consider the placement of fillet radii to avoid stress concentrations. 

If you’re using an engineering company to produce your prototype, make sure to ask about what design elements they are planning on using to ensure that the physical properties of your final product meet your needs.
