Ductile Iron Casting Part Series 8
JHshukong
Cast from ASTM A532 Grade IIIA and EN-GJS-1000-5, these parts undergo post-casting CNC machining to achieve IT8-10 tolerance, ideal for precision machinery, robotics, and automation systems.
Wear Resistance & Precision
Hardness & Tolerance:
Surface hardness HRC 50-55 (via induction hardening), wear loss ≤25mg/1000 cycles (ASTM G65 Method B), with critical dimensions held to ±0.05mm (IT8).
Machined surfaces achieve Ra ≤1.6μm, suitable for press fits, bearing seats, and sealing interfaces.
Alloy Selection: High-chromium ductile iron (Cr 1.5-2.5%) enhances carbide formation, resisting adhesive and abrasive wear in high-speed sliding applications.
Precision Manufacturing Process
Casting-Machining Integration:
Low-pressure casting ensures uniform wall thickness and minimal machining allowances (0.5-1mm), reducing machining time by 40% compared to rough castings.
5-axis CNC machining for complex geometries (e.g., helical gears, curved surfaces), with positional accuracy ±0.03mm for bolt hole patterns.
Quality Assurance
Dual Inspection:
Casting stage: X-ray for internal defects, MPI for surface cracks (defect rate ≤0.5%).
Machining stage: CMM inspection (accuracy ±0.02mm) for critical features, with statistical process control (SPC) maintaining Cpk ≥1.67.
Material Traceability: Each part linked to melt lot, heat treatment, and machining records via blockchain, compliant with ISO 22309:2019.
Design Flexibility
Feature Capability:
Thin walls (3-5mm), deep bores (L/D ≤15), and tight-radius corners (R ≥2mm), enabled by advanced mold technology and precision grinding.
Custom coatings: Teflon®-coated surfaces (friction coefficient ≤0.15) for low-lubrication environments (e.g., food processing conveyors).
Precision Machinery:
Robotics joints, linear guide rails, and automation components (ISO 20341 compliant), ensuring smooth motion and long life in high-precision systems.
Medical Equipment:
Surgical robot arms, imaging device brackets, and orthopedic testing fixtures (ISO 13485 certified), with biocompatible coatings available (e.g., titanium nitride).
Aerospace Ground Support:
Satellite tracking mounts, drone landing gear components, and avionics brackets (AS9100D compliant), meeting NASA dimensional stability requirements.
Precision Leadership
Only supplier offering ductile iron castings with IT8 tolerance and HRC 55+ hardness, validated by aerospace-grade inspection equipment.
Advanced Tooling
In-house EDM and wire cutting for hard materials (HRC ≥50), enabling intricate features impossible with traditional machining methods.
Rapid Response
10-day turnaround for precision-machined prototypes (casting + machining), 50% faster than industry average for complex components.
Compliance & Certification
Certified to AS9100D (aerospace), ISO 13485 (medical), and IATF 16949 (automotive), with materials compliant with REACH, RoHS, and Prop 65.
