【Industry Pain Points】Three Major Obstacles of Traditional Cutting One new‑energy‑vehicle component supplier once faced production bottlenecks. Its flagship product was aluminum‑alloy battery trays. After conventional plasma or CO₂ cutting, severe edge dross remained. Manual polishing took up over 30 % of total working hours. Worse still, the large heat‑affected zone caused minor plate deformation and uneven assembly gaps, which directly triggered welding defects such as incomplete fusion and porosity during subsequent laser welding. The yield rate lingered around 85 %. High rework costs and low delivery efficiency became major obstacles restricting production expansion.
【Three Core Scenarios to Unlock Breakthrough Solutions】 To tackle the above‑mentioned pain points, Eagle Laser introduced high‑precision fiber laser cutting machines and QCW precision‑cutting solutions to restructure the customer’s workflow, achieving cost reduction and efficiency improvement in three core application scenarios:
① High‑precision Cutting before Battery‑Tray Assembly Welding Battery trays are assembled and welded from multiple aluminum‑alloy profiles, which impose strict requirements on cutting cross‑sections and assembly gaps. Eagle Laser’s equipment adopts a high‑beam‑quality fiber laser together with high‑pressure nitrogen cutting technology, delivering an extremely small focused laser spot and highly‑concentrated energy density. Cut surfaces are smooth and burr‑free without oxidation discoloration. Assembly gaps are stably controlled within 0.1 mm. This eliminates secondary polishing procedures and provides perfect fit‑up conditions for subsequent laser autogenous welding, lowering welding porosity rate below 0.5 %.
② Precision Machining of Cold‑Plate Flow Channels and Micro‑Holes Internal flow channels of cold plates have complex geometries. Conventional stamping dies incur high opening costs and offer poor flexibility. The Eagle Laser QCW (Quasi‑Continuous‑Wave) precision fiber laser cutter adopts pulse mode to precisely control heat input and realize “cold machining on thermally‑sensitive materials”. Its heat‑affected zone is reduced to micron level, effectively preventing thermal deformation of thin aluminum‑alloy plates during complex flow‑channel cutting. Meanwhile, the machine easily processes micro‑hole arrays on workpieces with thicknesses from 0.5 mm to 3 mm, producing crack‑free, smooth hole walls that meet strict air‑tightness requirements of cooling systems.
③ Flexible Vision‑Guided Cutting for Lightweight Structural Parts Against the market trend of multi‑variety, small‑batch orders, production‑change‑over efficiency becomes critical. Eagle Laser cutting machines can be optionally equipped with a CCD visual positioning system. Plates can be placed randomly; the vision camera recognizes contours within milliseconds and automatically completes deviation compensation. No special fixtures are required. Operators can call pre‑saved cutting process libraries with one click, shortening change‑over time from hours to minutes. Combined with automatic loading‑unloading modules, the production system upgrades from standalone machining to a flexible intelligent manufacturing unit.
【Cost Reference & Performance Data】 After deploying Eagle Laser’s cutting solution, the component supplier obtained remarkable economic benefits: ‑ Sharp efficiency improvement: Aluminum‑alloy cutting speed increased by 3‑5 times compared with traditional processes, completely removing production‑capacity bottlenecks. ‑ Significant cost reduction: Die amortization and 30 % of polishing labour costs were eliminated, cutting comprehensive processing expenses by 40 %. ‑ Qualified yield achieved: Cutting dimensional accuracy reaches ±0.05 mm, and the subsequent welding yield remains stably above 99 %.
