Manufacturer of aluminum cast auto parts intake manifolds and oil pans

Dandong Pengxin Machinery – A Tier 1 supplier of high-integrity aluminum gravity casting solutions for automotive powertrains, specializing in intake manifolds and oil pans with 20+ years of OEM/ESM collaboration.

Key Highlights:

Process Expertise: Permanent mold gravity casting for superior metallurgical properties (low porosity, high fatigue resistance).

Materials: A356-T6, A357, and custom alloys for thermal/mechanical performance.

2. Product Advantages (Gravity Casting Focus)

Intake Manifolds

Key Benefits:

Optimized Flow Paths: Complex internal geometries (min. wall thickness: 3mm) achievable without welding.

High-Temperature Resistance: T6 heat treatment ensures stability under turbocharged conditions (up to 250°C).

Leak-Free Guarantee: X-ray inspected with helium leak testing (<0.5 cc/min).

Oil Pans

Key Benefits: Impact Resistance: Fine-grained microstructure outperforms HPDC in durability testing (e.g., stone chip resistance).

Integrated Design: Molded-in baffles/sensor mounts reduce assembly costs.

Deep-Draw Capability: Tilt-pour technology for cavities >150mm depth.

3. Technical Capabilities

Equipment: Automated tilt-pour systems (HWS, Germany) with ±0.5° angle control. CNC machining centers for post-casting finishing (Mazak 5-axis).

Quality Assurance: 100% X-ray/UT inspection (NADCAP compliant). CMM measurement (critical tolerances: ±0.15mm).

4. Industry Applications

Supplied turbocharged intake manifolds to Honeywell Garrett with copper-inserted EGR ports, reducing thermal deformation by 30%." *

Hybrid EV oil pan with coolant channel integration, achieving 22% weight savings vs. steel stampings.

5. Certifications & Sustainability

Standards: IATF 16949, PPAP Level 3.

Eco-Friendly: Closed-loop aluminum recycling (95% scrap reuse), ISO 14001 certified.

6. Call to Action
