Bridging the 30-Year Gap: Trumbull Insights on the Obsolescence Challenge

In a recent analysis, McKinsey & Company highlighted a critical "two-speed" challenge facing Industrial and Aerospace OEMs: Equipment life cycles are stretching to 30+ years, but the internal components supporting them have life cycles of less than five.
When a critical mechanical part becomes obsolete, whether because a supplier went under or the original tooling was scrapped, the resulting non-recurring engineering (NRE) costs can be staggering. McKinsey estimates these costs in the billions for the aerospace sector alone.
At Trumbull Foundry, we offer small part/run capabilities with heat sizes as low as 100 pounds and don’t believe an entire machine should be sidelined because a single casting is "out of print." Here is how we use our Rapid Prototyping framework to help OEMs navigate the obsolescence trap.
Eliminating the "Two-Speed" Disparity
The McKinsey report notes that OEMs often face a choice: undertake a full, costly redesign or hunt for "ghost" inventory. Trumbull offers a third way. By utilizing 3D Laser Metrology, we "resurrect" obsolete parts.
We capture the exact geometry of your last remaining physical part, even if it's worn or broken, and create a high-precision digital twin. This allows you to maintain 30-year equipment with 2026 technical accuracy, bypassing the need for a total system redesign.
Slashing NRE Costs with Tool-less Production
The biggest barrier to replacing a legacy casting is the cost and time of creating new patterns. McKinsey suggests that a systematic approach can reduce obsolescence management costs by up to 35%.
Trumbull accelerates this by utilizing 3D-printed sand molds. This "tool-less" casting process eliminates the $20,000+ pattern fee and the 10+ week wait time. We go from a digital scan to a first-article pour in days, providing the "speed as a service" that modern supply chains demand.
Obsolescence Challenge Opportunity: Material Upgrading While Replacing
The age old saying of "the problem isn't the problem; it's your attitude about the problem" has it's time to shine here. Obsolescence isn't just a risk; it’s an engineering opportunity. When we replicate a legacy component, we don't just copy the past. We help OEMs bring new life to their specs.
Gray Iron / Ductile Iron: Upgrade brittle legacy parts to high-yield ductile iron for superior fatigue life.
Alloy Optimization: Transition to specialized stainless or Ni-Resist alloys to meet 2026 environmental and stress requirements.
Domestic Resilience for Long-Life Assets
We noted that McKinsey’s research emphasizes the importance of identifying alternate, reliable suppliers to avoid future disruptions. With 150,000 sq. ft. of capacity in Niles, Ohio, Trumbull Foundry serves as the domestic anchor for OEMs who can no longer risk the "port-to-plant" anxiety of overseas sourcing. Made in America and proud of it.
We provide the industrial muscle (1 to 3,000 lbs.) and the technical grit to ensure your equipment stays on the line. The Bottom Line: You don’t have to accept obsolescence as a cost of doing business. Whether you have the original prints or absolutely nothing, Trumbull Foundry has the technology to keep your legacy assets moving.
Is obsolescence threatening your uptime? It would be our pleasure to serve businesses like yours that keep America strong. View our Rapid Prototyping Capabilities and let’s get your equipment back to "Day One" performance.
