For BMW enthusiasts and automotive engineers seeking uncompromised engine protection and performance, Dandong Pengxin introduces its newly developed Oil Sump specifically engineered for various BMW models. Utilizing advanced aluminum gravity casting technology, this oil pan delivers superior durability, optimal thermal management, and perfect OEM fitment, ensuring your BMW's engine operates with maximum efficiency and reliability.
Premium Material: A356-T6 Aluminum Alloy
This oil sump is manufactured using A356-T6 aluminum alloy, the industry benchmark for high-performance cast components. The A356 alloy offers an exceptional combination of strength, corrosion resistance, and castability, while the T6 heat treatment (solution heat treatment and artificial aging) enhances its mechanical properties to achieve a tensile strength of 240 MPa and yield strength of 165 MPa. This material provides excellent resistance to road impact and thermal distortion, along with superior heat dissipation characteristics that help maintain optimal oil temperatures - crucial for both daily driving and performance applications.
Advanced Gravity Casting Process
Our manufacturing employs the permanent mold gravity casting process, where molten A356 aluminum is poured into precision-machined steel molds under controlled atmospheric conditions. This process creates components with denser microstructure and lower porosity compared to other casting methods, resulting in:
Enhanced metallurgical integrity with improved pressure tightness
Superior dimensional accuracy and consistent wall thickness
Excellent surface finish requiring minimal post-machining
Higher mechanical properties through controlled solidification
The process allows for optimized internal baffling designs that help maintain oil around the pickup during cornering and acceleration, preventing oil starvation that could lead to engine damage.
Precision Engineering and Quality Assurance
Each oil pan undergoes comprehensive post-casting processing:
CNC machining of sealing surfaces ensuring perfect block interface
Precision drilling and tapping of all mounting points
Helium leak testing verifying 100% pressure integrity
Dimensional validation using coordinate measuring machines
Performance and Application Excellence
This gravity cast oil sump provides significant advantages:
Maintains stable oil pressure during aggressive driving maneuvers
Reduces oil temperatures by 10-15°C through improved heat dissipation
Withstands impact forces exceeding OEM requirements
Ensures perfect fitment with original mounting points and clearances
Designed as direct replacements for multiple BMW series including 3, 5, and 7 models, these oil pans restore and enhance the lubrication system's reliability. The optimized internal geometry and baffling design specifically address the oil control challenges in BMW's performance-oriented engines.
Dandong Pengxin's commitment to quality ensures each oil sump meets or exceeds original equipment specifications, providing BMW owners with a durable, high-performance solution that protects their engine investment while delivering the quality and reliability expected from a premium automotive component.
