In the front lines of mining and quarrying operations, equipment maintainers and procurement managers often get stuck in a frustrating loop: the cone crusher on the production line is still performing reliably, but due to the machine's age or lost original blueprints over years of use, key wear parts like liners and mantle bowls become nearly impossible to replace accurately.
When you're facing the dilemma of "got the machine, no drawings, can't buy OEM parts," Duma Machinery steps in with a comprehensive one-stop solution powered by expert reverse engineering-from mapping out dimensions to upgrading performance.
Breaking Free from Downtime Worries Caused by Aging Equipment and Missing Drawings
For many long-running quarries, the biggest fear is running out of spares for older models. The original manufacturer might have discontinued them, or the high costs and long import lead times could push your line to the brink of extended shutdowns. Even if you have zero original drawings, as long as the equipment is still operational or you have worn-out samples on hand, we can use technical methods to recreate 100% compatible wear parts. This keeps your legacy machines running steadily without forcing a full replacement.
Reverse engineering isn't just copying-it's a precise, scientific reconstruction process. In Duma's 42,000 m² in-house factory, we guarantee that custom parts are "plug-and-play" ready.
Duma offers full reverse engineering and custom remanufacturing services: Send us your worn samples as a physical reference, and our engineering team will use specialized tools for on-site or lab-based measurements. We'll reconstruct the original geometry from remaining dimensions, ensuring tolerances match perfectly with mainstream brands like Metso or Sandvik. We also perform in-depth material analysis via high-magnification metallography and spectroscopy to diagnose failure causes and ensure the new parts have no network carbide precipitation in their structure. Drawing on our experience with over 4,000 mold sets, we can quickly develop or tweak molds for accurate casting. Through our fully in-house production, we handle prototyping and optimization, with rigorous first-article inspections and heat treatment monitoring to make sure custom spares not only look the same but fit precisely, run stably, and last longer.
Duma Mold Warehouse
Duma's reverse engineering goes beyond replication-it's about tailored upgrades in materials and processes for superior performance. Based on your ore's hardness and abrasiveness, we can optimize part compositions, upgrading standard Mn13 or Mn18 to higher-performing Mn22 ultra-high manganese alloys. For extreme conditions, we add TiC titanium carbide inserts to boost lifespan in high-wear zones. Our proprietary controlled solution heat treatment and water quenching ensure liners start at around HB200 hardness, then rapidly work-harden under impact to over HB500, providing solid wear protection.
We understand the caution when switching suppliers, so Duma offers low MOQ trial orders. Start small, test on-site, and verify quality firsthand. Experience our parts' excellent work-hardening and consistent heat treatment in real use. Once validated, our robust large-scale production ensures reliable, long-term supply.
Missing drawings shouldn't halt production-it's a solvable issue. As a direct-owned factory integrating R&D and manufacturing, Duma specializes in tackling complex mining spare challenges with reverse engineering expertise.
If your old cone crusher needs new parts, reach out to Duma's engineering team. We'll assess if we can solve your real-world production headaches.
