Ductile Iron Casting Part Series 1
JHshukong
Designed for automotive powertrain and suspension systems, our Automotive Manufacturing High-Yield Strength Ductile Iron Casting Part Series 1 offers a lightweight, cost-effective alternative to steel, combining high yield strength with excellent formability. Cast from ASTM A536 Grade 65-45-12 and EN-GJS-400-18, these parts meet the rigorous demands of passenger vehicles and commercial trucks, enabling weight reduction and fuel efficiency.
Automotive-Grade Performance
Yield Strength Leadership:
Yield strength 45ksi (310MPa), 20% higher than standard ductile iron, supporting load-bearing applications like suspension arms and steering knuckles.
Elongation ≥12%, enabling cold forming and crash energy absorption, critical for safety-compliant automotive components (FMVSS 208).
Microstructure Purity: Ferritic matrix (≥90%) with nodular graphite size ≥8 (ISO 945), enhancing fatigue life (10⁸ cycles at 120MPa) for wheel hubs and brake calipers.
Lightweighting Solutions
Thin-Wall Technology: Successfully casts 3-5mm walls for lightweight components, achieving 25% weight reduction compared to gray iron without compromising strength.
Design Optimization: Ribbed structures and hollow sections via 3D-printed cores, enabling CAE-optimized designs for electric vehicle battery mounts and chassis components.
Quality & Compliance
IATF 16949 Certified: 100% traceability from raw material to assembly, with each part serialized and linked to PPAP Level 3 documentation.
Surface Finish: Electrogalvanized (8μm) or e-coat (50μm) for automotive-standard corrosion protection (salt spray 1000h, GM9540P compliant).
Process Efficiency
High-Volume Production: Automated green sand lines with 3-minute cycle time, capable of 10,000+ pcs/day for mass-market automotive components.
Precision Machining: CNC machining to IT10 tolerance (±0.1mm) for bolt holes and mounting surfaces, ensuring seamless assembly with OEM specifications.
Passenger Vehicles:
Suspension control arms, steering knuckles, and brake caliper brackets (IATF 16949 certified), meeting GM, Ford, and Toyota material specifications.
Commercial Trucks:
Axle housings, differential cases, and transmission components (SAE J2931 compliant), withstanding 1 million+ miles of heavy-duty operation.
Electric Vehicles:
Lightweight battery brackets, motor mounts, and structural components, contributing to 5-10% range improvement through weight reduction.
Automotive Production Leadership
10+ years as a Tier 1 supplier, with experience in Just-In-Time (JIT) delivery and zero PPM quality performance for global OEMs.
Material Innovation
Developed a proprietary low-carbon ductile iron (C ≤0.08%) for improved weldability in electric vehicle battery enclosures, compliant with UL 2580 safety standards.
Sustainable Manufacturing
90% sand recycling, 100% renewable energy in heat treatment, and water-based coatings, aligning with OEM sustainability goals (e.g., VW Group E-Wheel-to-Wheel).
Engineering Partnership
Collaborative design support using CATIA and AutoForm, optimizing wall thickness and cooling channels to meet CAE performance targets.
