Overview
Recommended Products

For owners and technicians maintaining GM's legendary 6.6L Duramax diesel engines, the engine oil pan serves as a critical foundation for lubrication system integrity and engine longevity. Specifically engineered for 2001-2010 model years, this heavy-duty cast aluminum oil pan delivers superior durability and performance compared to conventional stamped steel designs. Manufactured to exact OEM specifications, it ensures perfect fitment and reliable service for LB7, LLY, LBZ, and LMM engine variants in commercial, agricultural, and heavy-duty transportation applications.

Material Excellence: Aerospace-Grade Aluminum

A356-T6 Aluminum Alloy: Delivering ultimate strength-to-weight ratio with excellent thermal conductivity
Precision Sand Casting: Ensuring uniform wall thickness (4-6mm) and optimal material density
Heat-Treated Construction: Solution treated and artificially aged to T6 temper for maximum hardness
Internal Baffling Design: Integrated turbulence-reducing baffles for consistent oil pressure

Advanced Manufacturing Process

Precision Casting Technology
- Computer-designed sand molds with optimized gating systems
- Controlled solidification process preventing porosity
- X-ray inspection for internal defect detection
CNC Machining Operations
- 5-axis machining of sealing surfaces within ±0.1mm flatness
- Precision threading for drain plug and sensor ports
- Surface finishing to Ra 3.2μm for optimal gasket sealing
Quality Validation
- Pressure testing to 45 PSI for leak-free guarantee
- Coordinate measurement machine verification
- Chemical composition certification per ASTM standards

Performance Advantages

Superior Heat Dissipation: Aluminum construction reduces oil temperatures by 15-20°C
Impact Resistance: Withstands road debris and off-road conditions
Corrosion Protection: Natural aluminum oxide layer prevents rust formation
Weight Reduction: 40% lighter than equivalent steel components
Dimensional Stability: Maintains seal integrity under thermal cycling

Technical Specifications

Capacity: 10-quart oil volume with proper sump design
Sealing Surface: Machined for OEM gasket compatibility
Drain Port: Standard 14mm threaded insert
Mounting Pattern: Exact OEM bolt hole configuration

Quality Control

At Pengxin-Casting, process control begins as early as in the planning and development phase of the products. We support our customers to perform all required tests and inspections in a laboratory. It goes without saying that our plants are certified according to ISO 9001 and IATF16949 in line with a validated quality management. As we strive to accomplish our zero-error policy, you can rely on the following process control measures: Drawing Control → Pattern Control → Raw Material Control → Molding Sand Control → Pouring Process Control → Raw Casting & Machining Control →Other Requirement Control→ Packing & Delivery Control.

Pattern Control

We simulate feeding syetem to check the pattern desgin from the filling process and material solidification,In this way, we can shorten the mold development cycle, reduce the number of mold trials and improve product quality.The software we use includes ‌Abaqus,‌Moldflow and Moldex3D,simulate feeding system, reduce casting defects and improve efficiency.
