In automotive engine systems, the oil pan serves as a critical component for lubrication management and engine protection. Our Aluminum Gravity Casting Automobile Oil Pan represents the pinnacle of foundry excellence, combining advanced metallurgy with precision manufacturing to deliver superior performance, exceptional durability, and perfect fitment for various vehicle applications.
Premium Material Selection
We utilize A356-T6 aluminum alloy as our primary material, specifically engineered for automotive applications. This alloy offers:
Excellent strength-to-weight ratio with tensile strength of 230 MPa
Superior corrosion resistance against engine oil and environmental factors
Outstanding thermal conductivity (151 W/m·K) for efficient heat dissipation
Enhanced fatigue resistance capable of withstanding engine vibrations
The T6 heat treatment process (solution treatment and artificial aging) further enhances mechanical properties while ensuring dimensional stability under thermal cycling conditions.
Advanced Gravity Casting Process
Our manufacturing employs permanent mold gravity casting technology, which provides significant advantages over other methods:
Controlled Filling: Molten aluminum fills molds by gravity, minimizing turbulence and gas entrapment
Rapid Solidification: Steel molds extract heat quickly, resulting in fine-grained microstructure
Dimensional Accuracy: Maintains consistent wall thickness (3-5mm) across complex geometries
Superior Surface Finish: Achieves Ra 6.3-12.5 without extensive post-processing
The process includes:
Computer-simulated mold design for optimal solidification patterns
Automated pouring systems maintaining precise temperature control
Real-time thermal monitoring during casting process
Controlled cooling to prevent internal stresses
Precision Engineering and Machining
Each oil pan undergoes comprehensive post-casting processing:
CNC machining of sealing surfaces ensuring flatness within 0.1mm
Precision drilling of mounting holes with ±0.05mm tolerance
Thread processing for drain plugs and sensor ports
Surface treatment options including powder coating and anodizing
