When evaluating casting suppliers, it’s natural to compare prices. But what many manufacturers don’t realize is that the cost of a casting is often determined long before production begins. Design decisions made during the engineering phase can significantly influence manufacturing complexity, lead times, machining requirements, and ultimately, the total cost of the finished component.
This concept is known as designing for manufacturability or designing for castability.
Designing for castability means creating components that can be produced efficiently while maintaining the performance, quality, and durability required for the application. Features such as wall thickness, draft angles, part geometry, radii, machining allowances, and gating considerations all impact how easily a casting can be produced. Small design changes made early in the process can often reduce manufacturing complexity, improve yield, and lower overall production costs without sacrificing performance.
At Waukesha Foundry, our engineering team works closely with customers early in the product development process to review casting designs and identify opportunities for improvement. In many cases, thoughtful design modifications can reduce machining requirements, minimize material usage, improve casting quality, and shorten production timelines.
These conversations are especially valuable when developing new products or transitioning existing components into production. By considering manufacturability before tooling is created, customers can avoid costly design revisions later while improving long-term production efficiency.
Designing for castability is about much more than reducing the cost of a single part. It’s about optimizing the entire manufacturing process, from tooling and production through machining, inspection, and delivery. The result is a casting that not only meets engineering requirements but also delivers greater value over the life of the project.
Whether you’re developing a new component or refining an existing design, involving your foundry partner early can make a measurable difference. At Waukesha Foundry, we combine engineering expertise, metallurgical knowledge, and decades of manufacturing experience to help customers develop casting solutions that balance performance, quality, and cost from the very beginning.
