Overview


Specializing in bespoke solutions, our Customized High Precision Ductile Iron Casting Parts offer unmatched flexibility in material, geometry, and performance, tailored to the most demanding industrial and aerospace requirements. Cast from premium alloys (e.g., ASTM A536 Grade 120-90-02, EN-GJS-1200-2) and processed via advanced techniques, these parts combine high precision with mechanical excellence, ideal for complex, one-of-a-kind components.


Features


Unlimited Customization

Material Flexibility:

Alloy formulations: From standard grades to proprietary blends (e.g., low-carbon ductile iron for cryogenic use, high-silicon ductile iron for heat resistance).

Heat treatments: Austempering, martempering, and custom cycles to achieve target properties (e.g., HRC 60 for wear, HB 180 for machinability).

Geometry Freedom:

Complex shapes: Undercuts, internal threads, and thin-wall structures (3mm) via 3D-printed sand cores and lost foam casting.

Size range: 0.5kg to 2000kg, with dimensional accuracy CT8-9 (ISO 8062) for aerospace and medical applications.


Precision & Quality

Dimensional Control:

CNC machining achieves IT7-8 tolerance (±0.02-0.05mm) for critical features, with CMM inspection ensuring compliance with AS9100D geometric tolerances.

Surface finish: Electropolishing to Ra ≤0.2μm for optical components and medical implants (USP Class VI compliant).

Defect Management:

100% CT scanning for complex parts, with defect rejection rate ≤0.1% for aerospace-grade components.


Engineering Collaboration

Design Support:

In-house engineers provide DFM (Design for Manufacturing) reports, suggesting wall thickness, draft angles, and gating systems to optimize castability.

FEA simulations for stress, thermal, and flow analysis, reducing prototype iterations by 50%.

Rapid Prototyping:

7-day turnaround for 3D-printed sand molds and 15-day delivery for first-off samples, ideal for R&D and custom machinery projects.


Industry-Leading Compliance

Certifications:

Aerospace: AS9100D, NADCAP accredited for NDT and heat treatment.

Medical: ISO 13485, biocompatible coatings (e.g., Parylene C) for implantable device components.

Traceability: Full material and process traceability via blockchain, with each custom part accompanied by a detailed qualification report.


Application


Aerospace & Defense:

Satellite structural components, missile guidance brackets, and drone transmission parts (AS9100D compliant), meeting NASA outgassing requirements.

Medical Devices:

Custom orthopedic implants, robotic surgery components, and diagnostic equipment parts (ISO 13485 certified), with surface finishes compliant with USP Class VI.

Advanced Machinery:

High-precision gears, telescope mounts, and semiconductor manufacturing components, ensuring micron-level accuracy and long-term stability.
