Top 7 Die Casting Design Tips

Good design is the basis for producing high quality die castings. Many factories are involved in the creation of the die, and once the die is formed, it is difficult to change it. This shows the importance of having a good design from the beginning.

The purpose of die casting design is to create castings that can maximize the function of the product. At the same time, die casting design should also pay attention to whether the production can be carried out quickly and effectively, to minimize the chance of defects of the product. In order to better achieve this goal, here are a few design tips to pay attention to.

Wall Thickness Uniformity

The design of die-casting machine should pay attention to the wall thickness difference around the casting. Even if it is not possible to create a 100% uniformity, the wall thickness error should be minimized. Different wall thickness can result in different cooling rates.

Different cooling rates can cause a lot of problems for castings, including changes the part size. At the same time, uniform wall thickness is also conducive to metal flow and casting filling integrity, and can greatly improve the quality of products.

Large Fillets and Corners 

In die casting design, make the inner and outer Angle radius of the casting as large as possible. This reduces the wear of dies, improves metal flow, makes castings stronger, and makes production easier and faster.

Ribs and bosses

Focus on theribs and bosses as much as possible. You can use these to eliminate sharp corners and increase the strength of the finished part.

Pockets 

You can reduce the weight by reducing the padding inside the parts. You can design a casting with strategic cavitation (what we call a "metal protector") to reduce your casting weight without sacrificing structural integrity. You can also use ribs to strengthen the assembly after reducing padding.

Draft

If you do not take craft into account during casting design, your casting will not be removed from the mold. You need to make sure that your die castings have a greater taper than the outer wall so that when the alloy solidifies and shrinks and fits more tightly to the inner wall. Proper drafting will make it easier to produce castings.

Same Side Die Dimensions

Another very important technique is to make sure that your critical dimensions are on the same side of the mold. This will lower your die casting price.

No Undercuts 

If you have a undercuts in the part design, your regular die casting mold will not work. You will need to add a slider (which is the moving part perpendicular to the drawing direction of the mold), but this will increase the time and cost of casting. So we need to avoid undercuts design as much as possible
