Overview
Recommended Products

In the realm of heavy infrastructure and transportation engineering, the integrity of structural components is paramount. Our China foundry specializes in the production of ductile iron bridge frames utilizing advanced shell casting technology. These critical structural elements are engineered to deliver exceptional performance under demanding load conditions, combining the superior material properties of ductile iron with the precision of modern shell casting processes to meet the rigorous requirements of global bridge construction and rehabilitation projects.

Material Excellence: Ductile Iron Advantages
We employ high-grade ductile iron (GGG40/50/60) that offers:

High Tensile Strength (400-600 MPa) with excellent yield strength
Superior Impact Resistance and toughness (elongation 10-18%)
Exceptional Fatigue Resistance for long-term cyclic loading capability
Good Corrosion Resistance through proper alloy composition
Excellent Casting Fluidity for complex structural geometries

Advanced Shell Casting Process
Our manufacturing methodology ensures precision and quality:

Pattern Preparation
- Precision metal pattern creation
- Thermal-controlled resin sand coating
- Automated mold assembly systems
Casting Excellence
- Computer-controlled pouring systems
- Optimized gating and riser design
- Controlled solidification monitoring
Post-Casting Processing
- Heat treatment (normalizing/annealing)
- Stress relieving for dimensional stability
- Precision machining of critical surfaces

Performance Characteristics

Load Capacity: Designed for highway bridge standards (HS20-44 loading)
Durability: Service life exceeding 50 years with proper maintenance
Weight Optimization: 15-20% lighter than equivalent steel structures
Seismic Performance: Excellent energy absorption characteristics
Weather Resistance: Suitable for various environmental conditions

Quality Control

At Pengxin-Casting, process control begins as early as in the planning and development phase of the products. We support our customers to perform all required tests and inspections in a laboratory. It goes without saying that our plants are certified according to ISO 9001 and IATF16949 in line with a validated quality management. As we strive to accomplish our zero-error policy, you can rely on the following process control measures: Drawing Control → Pattern Control → Raw Material Control → Molding Sand Control → Pouring Process Control → Raw Casting & Machining Control →Other Requirement Control→ Packing & Delivery Control.

Pattern Control

We simulate feeding syetem to check the pattern desgin from the filling process and material solidification,In this way, we can shorten the mold development cycle, reduce the number of mold trials and improve product quality.The software we use includes ‌Abaqus,‌Moldflow and Moldex3D,simulate feeding system, reduce casting defects and improve efficiency.
