This combination allows fabricators to produce components that would otherwise require multiple manufacturing methods and separate production facilities.

Custom sheet metal leverages Haas machining to achieve designs of greater complexity and precision. Intricate mounting features, precisely machined sealing surfaces, and complex contours can be added to sheet metal components through secondary machining operations. The dimensional stability and repeatability of Haas systems ensure that these machined features maintain their relationship to the sheet metal's formed geometry. This capability proves particularly valuable when sheet metal components must interface with other precision-machined parts in an assembly, as the machining operations can ensure perfect alignment and fit.

Case studies demonstrate successful integrations of these technologies. A Hong Kong-based electronics manufacturer combined custom sheet metal enclosures with Haas-machined mounting features to create a sophisticated network switching system. The sheet metal provided the structural framework and electromagnetic shielding, while the Haas-machined features ensured precise alignment of circuit boards and connectors. This approach reduced assembly time by 35% and improved product reliability by eliminating fitment issues. Another example comes from the medical industry, where a surgical equipment developer used custom-formed stainless steel components with Haas-machined precision surfaces to create a minimally invasive surgical platform. The combination allowed for complex fluid pathways to be formed in the sheet metal, while critical sealing surfaces and mounting features were machined to surgical-grade tolerances. These examples illustrate how the strategic combination of these technologies solves manufacturing challenges that neither approach could address independently.
