Die-Casting Supplier: Forging the Precision Skeleton for the Power Heart
Within the complex "power heart" of engines, high-pressure die-cast aluminum alloy components serve as indispensable precision skeletons. As a core supplier, we specialize in manufacturing critical structural parts such as cylinder blocks, cylinder heads, transmission housings, and oil pans. For instance, the aluminum alloy cylinder block for a German luxury V8 engine utilizes a 5,000-ton cold-chamber die-casting machine with high-vacuum technology, achieving thin-wall complex structures at 3.5mm±0.2mm wall thickness with porosity controlled below 0.05%. Through an intelligent real-time injection control system, we precisely manage molten aluminum temperature (720±10°C), injection velocity (6m/s), and intensification pressure (900 bar), ensuring structural integrity under 200 bar combustion pressure. For hybrid EVs, our integrated motor housing castings (e.g., for BYD DM-i systems) enhance cooling channel precision to ±0.15mm with thermal conductivity reaching 160 W/m·K, boosting system power density beyond 3.5 kW/kg.
Process Breakthroughs Empower Performance Leaps
Addressing 1,050°C thermal shock challenges in turbocharger housings (e.g., BorgWarner E-Turbo housings), we innovatively apply high-silicon molybdenum alloy (Si18%-Mo3%) with local squeeze casting, improving high-temperature creep resistance by 40%. To meet China VI emissions, our EGR cooler die-cast housings adopt ultra-dense micropore standards (X-ray inspection: zero defects >0.3mm) with helium leak rates ≤10⁻⁶ mbar·L/s. In lightweighting, a mega-casted front compartment frame (1,200×800mm) for a US pickup replaces 37 steel parts, reducing weight by 31% while increasing torsional stiffness by 15%. Via precision mold temperature control (±3°C) and AI defect prediction, we maintain flatness tolerance of VW EA888 chain cover plates at 0.08mm/300mm, significantly reducing oil leakage risks.
Collaborative Innovation Drives Industrial Transformation
As electrification accelerates, we pioneer 8,000-ton mega-casting cells to mass-produce 1.8×1.5m rear underbody assemblies (integrated with crash beam mounts) for NEV makers, cutting weld points from 186 to 8. For e-drives, the water-cooled motor end shield developed for Huawei DriveONE integrates cooling channels and electromagnetic shielding layers, reducing eddy current losses by 50%. With five smart manufacturing bases across Yangtze River Delta/GBA (combined annual capacity: 28,000 tons) and CNAS-certified labs (CT scanning/high-cycle fatigue testing), we co-develop next-gen powertrains like Geely Thor Power/Great Wall 3.0T V6, providing full-chain material-process-validation capabilities to anchor both ICE evolution and e-mobility revolution.
