Case Study: Achieving a 50% Weight Reduction with Design Optimization
In the competitive world of manufacturing, especially for industries like aerospace and automotive, every gram saved translates to significant gains in fuel efficiency, performance, and cost. This case study explores how our onestop CNC machining and batch processing factory partnered with a client to achieve a remarkable 50% weight reduction in a critical aluminum component through advanced design optimization.
The Challenge: A Heavy and Costly Bracket
Our client, an automotive supplier, approached us with a traditional aluminum bracket. While functional, its solid, prismatic design was heavy, leading to higher material costs and increased fuel consumption in the final vehicle application. The client's primary goals were to drastically reduce weight without compromising the part's structural integrity and loadbearing capabilities.
Our Solution: A Synergy of DFM and Advanced Machining
Instead of simply machining the existing design, our engineering team initiated a Design for Manufacturability (DFM) analysis. We proposed a complete redesign leveraging several key strategies:
CNC machining
1. Topology Optimization: Using sophisticated software, we simulated the operational loads and stresses on the bracket. The software algorithmically removed material from areas experiencing low stress, resulting in an organic, skeletallike structure that was both incredibly strong and exceptionally light.
2. Internal Lattice Structures: For noncritical volumes within the part, we designed and incorporated internal lattice structures. These grids provide excellent strengthtoweight ratios, similar to the internal structure of bones, further reducing mass.
3. Strategic Ribbing and Pocketing: We replaced thick walls with a network of thin, strategically placed ribs. Additionally, nonfunctional material was removed through deep pocketing on all accessible faces, eliminating every possible gram of excess weight.
The optimized design was a stark contrast to the original blocky component. It was then precisely manufactured from a highgrade 6061 aluminum billet using our multiaxis CNC milling centers. The complex geometries, including the internal lattices and thin ribs, were machined with high precision, demonstrating our capability to produce intricate, optimized parts in batch quantities.
The Result: Lighter, Stronger, and More Efficient
The outcome exceeded expectations. The final component achieved a 50% reduction in weight compared to the original design. Crucially, Finite Element Analysis (FEA) confirmed that the new design met all structural and safety requirements. For our client, this resulted in:
Lower Material Costs: Less raw material was required per part.
Improved EndProduct Performance: The lighter component contributed to better vehicle fuel efficiency and handling.
Reduced Shipping Costs: Lighter batches meant lower logistics expenses.
This project is a powerful testament to how modern design philosophy, combined with precision batch machining, can revolutionize component performance. We don't just manufacture your designs; we collaborate to reimagine them for a lighter, stronger, and more costeffective future.
