At TXMETAL, quality is engineered into every phase of our custom iron casting workflow. We follow ISO 9001:2015 procedures and APQP/PPAP quality management so that gray iron, ductile iron, and ADI castings consistently meet OEM requirements on dimensional accuracy, mechanical properties, and durability. Our controls cover chemistry, process capability (Cp/Cpk), traceability, and final conformity.

  • Prevents porosity, shrinkage, cracks, misruns, and core shift
  • Ensures stable performance in automotive, industrial, and heavy equipment
  • Reduces scrap and rework, shortening lead times and total cost
  • Supports APQP/PPAP submissions, capability studies (Cp/Cpk), MSA, and full heat/batch traceability
This image shows professional foundry engineers working at their desks with dual monitors, focusing on casting design and data analysis. In a modern foundry, engineering teams utilize CAD and CAE software to design and optimize the production of gray iron, ductile iron, and austempered ductile iron (ADI) castings. These processes ensure precision, efficiency, and reliability in manufacturing, supporting industries such as automotive, machinery, and heavy equipment.

Raw Material Inspection

Spectrometer analysis and visual inspection for all pig iron, scrap steel, and alloying elements to ensure chemical consistency from the very start.

Molding & Core Verification

Sand property testing, pattern inspection, and dimensional checks on cores to prevent casting defects before production begins.

Melting & Pouring Control

Real-time melt temperature monitoring, alloy adjustments for precise metallurgy, and pre-pour chemical verification to maintain material integrity.

Cooling & Shakeout

Controlled cooling cycles to minimize stress, visual inspection for early defect detection, and initial cleaning for better downstream processing.

Machining Stage QC

CMM-based dimensional verification at critical machining points, supported by PPAP documentation for OEM compliance.

Final Inspection

Comprehensive dimensional reports, tensile strength testing, hardness measurements, and surface roughness verification to ensure every part meets specifications.

Packaging & Shipping

Protective export-grade packaging, complete export documentation, and shipment verification to safeguard quality until delivery.

Strengthens TXMETAL’s reputation as a trusted custom iron casting supplier for global OEM partnerships.
