Chinadiecasting work with our customers to design their castings to integrate functions while optimizing the functionality to make casting easier to produce. This allows our customers to receive a casting that minimizes costs while minimizing production costs.
Customers often know what features they want, and we know how to make projections that meet those needs. Here are the five tips we can help you understand our processes and the reasons behind our design guidance.
Keep the casting uniform wall thickness. This can improve the flow of metal and fill the casting. Due to the difference in cooling rate in the casting wall, it can also minimize dimensional changes.
The corner and radius of the casting should be as large as possible. This improves the filling of the casting and increases the die life due to the reduced degradation of the die steel in the sharp corner area.
Include drafts in casting designs. The inner wall of the casting should be more taper than the outer wall of the casting. In order to remove the casting from the mold, need to draft. Inside the wall more of the raw material is cast alloy shrink in the curing. Castings tend to be smaller and closer fit inside the castings. Increased ventilation allows for easier removal of castings from the mold.
Keep the key dimensions on the same side of the mold. Since the mold has a moving part, the size based on more than one part will have a greater change than the size based on the features in the single die part. Larger changes in size will require greater tolerances, which may be unacceptable for the functionality of the castings. When this happens, it requires additional operations on the cast to meet the tolerances, which will result in increased customer costs.
If possible, avoid undercuts. Undercutting geometry can not be cast in standard die casting molds. The undercut requires the addition of a moving mold called "slider" to cast this piece of casting geometry. The added "slider" increases the cost of the mold. The undercut geometry also affects the time required to make the casting, which increases the cost of the customer.
Our primary goal is to always provide our customers with high quality products at competitive prices. Working with customers, we can help develop casting designs that meet functional and casting requirements. click https://www.chinadiecasting.co to see more information.
