OEM & ODM Factory's Custom Metal Casting Service Specializes in Ducutile Iron/Grey Iron Sand Casting High Quality Cast Iron Part

As a professional OEM & ODM metal casting specialist, we provide comprehensive custom sand casting solutions focused on ductile iron and grey iron components. Our foundry combines advanced manufacturing technology with extensive metallurgical expertise to deliver high-quality cast iron parts that meet precise specifications for diverse industrial applications worldwide.

Material Selection and Performance Characteristics

Our specialization in ferrous metals encompasses two primary material groups with distinct performance advantages:

Ductile Iron Castings
Also known as nodular iron, our ductile iron castings feature spheroidal graphite structures that deliver exceptional mechanical properties. These materials offer superior tensile strength (typically 414-827 MPa), excellent impact resistance, and good elongation characteristics (2-18% depending on grade). The nodular graphite formation provides durability comparable to steel while maintaining excellent castability and machinability.

Grey Iron Components
Our grey iron castings contain flake graphite structures that provide natural vibration damping capacity and outstanding wear resistance. These materials demonstrate excellent compressive strength and thermal conductivity, making them ideal for applications requiring stability under thermal cycling. The graphite flakes also create natural lubricity, reducing friction in moving components.

Advanced Sand Casting Manufacturing Process

Our production methodology employs sophisticated sand casting techniques optimized for iron alloys:

Pattern Design and Manufacturing
We create precision patterns using wood, plastic, or metal materials based on production requirements. Our engineering team utilizes CAD/CAM systems to optimize pattern design for proper shrinkage allowance and draft angles, ensuring dimensional accuracy in final castings.

Molding and Core Making
We employ both green sand and resin sand molding systems, selecting the appropriate method based on production volume, complexity, and surface finish requirements. Our chemically-bonded sand systems enable production of complex cores for intricate internal geometries, maintaining dimensional stability throughout the casting process.

Melting and Pouring Control
Our medium-frequency induction furnaces maintain precise chemical composition and pouring temperatures. We implement scientifically-designed gating and feeding systems to ensure proper metal flow and directional solidification, minimizing casting defects and ensuring consistent microstructure development.

Quality Assurance and Technical Capabilities

We maintain comprehensive quality control protocols throughout our manufacturing process:

• Spectrochemical analysis for precise chemical composition control

• Mechanical testing to verify tensile strength, hardness, and elongation

• Microstructure examination using metallurgical microscopy

• Non-destructive testing including magnetic particle and ultrasonic inspection

• Dimensional verification with coordinate measuring machines

Industrial Applications and Solutions

Our custom iron casting services support multiple industry sectors:

• Automotive and Transportation: brake components, engine brackets, transmission cases

• Industrial Machinery: pump housings, valve bodies, gear blanks, machine tool structures

• Infrastructure Development: pipe fittings, manhole covers, drainage grates

• Power Generation: turbine components, compressor housings, equipment bases

By integrating traditional casting expertise with modern manufacturing technology, we deliver OEM and ODM solutions that balance performance requirements with production efficiency. Our engineering team collaborates closely with clients to optimize designs for manufacturability, application performance, and cost-effectiveness, ensuring reliable solutions for demanding industrial environments.
