Custom Grey Cast Iron Ductile Iron Casting Professional Fc250 Fcd500 Casting Services

As a professional foundry specializing in iron casting, we provide comprehensive solutions for both grey cast iron (FC250) and ductile iron (FCD500) components. Our manufacturing expertise combines traditional casting knowledge with modern technology to deliver high-quality castings that meet diverse industrial requirements for strength, durability, and performance.

Material Excellence and Performance Characteristics

Our services encompass two primary iron materials with distinct mechanical properties:

FC250 Grey Cast Iron
This high-quality grey iron offers excellent casting characteristics and reliable performance with tensile strength of 250 MPa. The material's graphite flake structure provides natural vibration damping capacity, superior wear resistance, and outstanding thermal conductivity. FC250 demonstrates good machinability and maintains dimensional stability under thermal cycling conditions, making it ideal for applications requiring noise reduction and thermal management.

FCD500 Ductile Iron
This high-strength ductile iron provides enhanced mechanical properties with tensile strength of 500 MPa and elongation of 7%. The spheroidal graphite structure offers excellent impact resistance, good fatigue strength, and improved ductility compared to grey iron. FCD500 maintains the corrosion resistance and castability of traditional iron while providing strength characteristics approaching those of steel components.

Advanced Casting Manufacturing Process

Our production methodology employs sophisticated foundry techniques:

Pattern Design and Manufacturing
We create precision patterns using CAD/CAM technology, incorporating proper shrinkage allowances and draft angles. Our pattern design optimizes gating and risering systems to ensure sound casting quality and minimal material waste.

Molding Technology
We utilize both green sand and resin sand molding systems based on production requirements:

• Green sand molding for high-volume production efficiency

• Resin sand systems for complex geometries and superior surface finish

• Automated molding lines ensuring consistent quality

• Controlled sand properties maintaining optimal mold strength

Melting and Pouring Control
Our medium-frequency induction furnaces maintain precise chemical composition and pouring temperatures. We implement advanced inoculation techniques for both grey and ductile iron, ensuring proper microstructure development and mechanical properties.

Quality Assurance and Technical Validation

We maintain comprehensive quality control throughout our manufacturing process:

• Spectrochemical analysis for precise chemical composition control

• Mechanical testing verifying tensile strength and hardness

• Microstructure examination confirming graphite formation

• Ultrasonic testing for critical application components

• Dimensional validation using coordinate measuring machines

Industrial Applications and Solutions

Our iron casting services support multiple industry sectors:

• Automotive Components: Engine blocks, brake discs, and transmission cases

• Hydraulic Systems: Pump housings, valve bodies, and manifold blocks

• Industrial Machinery: Machine tool structures, equipment bases, and gear blanks
