Iron Casting Quality Control & CNC Machining Inspection
Integrated Quality Control from Melt to Machined Casting
YBmetal ensures consistent, defect-free castings through end-to-end Iron Casting Quality Control, covering digital melt tracking, engineering simulation, foundry inspection, and in-house CNC precision validation. As a trusted iron casting supplier in China, we serve global OEMs with APQP/PPAP-compliant workflows, GD&T controls, and Six Sigma-based traceability systems.
Melt Process & Metallurgical Control
Digital Melt Management
We utilize a digitally controlled melting system to ensure stable carbon and silicon control, real-time temperature management, and batch traceability. All data is archived and linked to product IDs, supporting root cause analysis and ISO-compliant documentation.
Process & Product Engineering
Our engineers leverage DFM, casting simulation, and Design of Experiments (DOE) to validate gating, cooling, and geometry decisions before tooling. This minimizes defect rates and ensures smoother sample approval.
Project Quality Planning (APQP / PPAP)
We implement a structured APQP process for all new projects, supported by full PPAP Level 3 documentation, including: ✅ Process FMEA & control plans ✅MSA, CMM, and SPC reports✅Dimensional and material certifications✅First article inspection and CoC
Data-Driven Quality Control
YBmetal system integrates 6Sigma methodology, SPC, and layered process audits (LPA), casting a digital management system to ensure casting repeatability. YBmetal tracks Cp/Cpk and yield metrics across batches to support continuous improvement.
Multi-Level Casting Inspection (Pre- and Post-Machining)
Casting Quality Inspection (Via Certified Foundries)
YBMETAL’s quality protocols govern all casting inspections, and results are cross-verified against incoming material checks before machining
Material Verification:
- Spectrometer analysis for chemical composition (e.g., C, Si, Mn, S, P, Cr, Mo, Ni, Cu)
- Tensile strength and hardness testing per ASTM/ISO standards
- Metallographic analysis for microstructure & nodularity (for ductile iron)
Dimensional Inspection:
- Manual and semi-automatic inspection tools
- CMM dimensional reports (as required for PPAP or FAI)
Surface & Visual Inspection:
- 100% visual inspection for casting defects: shrinkage, cracks, blowholes
- Surface roughness checks (Ra values per part spec)
NDT Capabilities (as requested):
- Magnetic Particle Inspection (MPI) for surface cracks
- Dye Penetrant Testing (DPT) for non-porous surface anomalies
- Radiographic testing (X-ray) for critical wall sections
Process & Traceability Control:
- Full batch traceability via unique lot numbers
- Control plans, FMEA, and production records
- Supplier certifications for ISO 9001 / IATF 16949
- Statistical Process Control (SPC) and 6 Sigma trial evaluation (on demand)
