Why Choose Our Cast Iron Services

Over 20 years of experience in producing durable and precision cast iron components — trusted by industries worldwide.

High Strength & Wear Resistance

Our cast iron parts are designed for load-bearing, vibration-damping, and wear-resistant applications — ideal for construction and heavy machinery. .

Material Flexibility

We offer both gray iron and ductile iron grades (HT200, QT450, QT500) to meet varied mechanical and performance needs. .

Short Lead Times

Standard lead times from 15 to 30 days. We support small batch prototyping and fast production turnaround. .

Strict Quality Assurance

All parts undergo dimensional checks, NDT (UT/RT/MT), and material testing to ensure structural integrity and consistency. .

Our Cast Iron Casting Process

From mold design to final inspection, our cast iron process ensures durability, dimensional accuracy, and cost-efficiency across all applications.

1.金型工学

Custom sand or resin molds are designed using CAD and simulation tools to optimize solidification and reduce internal defects in iron castings. .

2. Iron Melting & Pouring

We melt gray or ductile iron in cupola or induction furnaces and pour into preheated molds — ensuring metallurgical stability and clean castings. .

3. Cooling & Cleaning

After controlled cooling, castings undergo shakeout, sand removal, and rough cleaning to prepare for further processing. .

4. Inspection & Finishing

Each part is inspected for dimensional accuracy and defects. Optional machining or surface treatment is applied based on final use. .

Our Iron Casting Capabilities

We provide custom iron casting services to support a wide range of industrial needs — from durable gray iron to high-strength ductile iron components.

FAQ – Frequently Asked Questions about Iron Casting

Iron casting involves pouring molten iron—typically gray or ductile iron—into molds to create shaped parts. It’s ideal for producing durable and cost-effective components.
Common grades include gray iron (HT200) and ductile iron (QT450, QT500), selected based on strength, wear resistance, and application needs.
  • Excellent vibration damping and wear resistance
  • Cost-effective for large volume production
  • Good machinability and thermal conductivity
  • Suitable for automotive, pump, and industrial components
  • Green Sand Casting
  • Resin Sand Casting
  • シェルモールド鋳造
The choice depends on the desired surface finish, dimensional accuracy, and production scale.
Yes. Ductile iron can be heat-treated to improve strength or toughness. Both gray and ductile iron castings can be precision machined as needed.
  • CAD-based mold design and simulation
  • Metallurgical testing and chemical analysis
  • Dimensional inspections and NDT (UT/MT) if required
  • Final surface and machining quality checks
These measures ensure reliable performance in demanding industrial environments.
