At TXMETAL, quality control is not a single inspection step—it’s a continuous, data-driven commitment integrated into every stage of our custom iron casting production. With 30+ years of foundry expertise, ISO 9001:2015 certification, and PPAP (Production Part Approval Process) methodology, we produce gray iron, ductile iron, and austempered ductile iron (ADI) castings that consistently meet stringent OEM specifications for dimensional accuracy, mechanical performance, and durability. Our QC system ensures castings meet the operational demands of automotive drivetrains, agricultural implements, construction machinery, and heavy-duty gearboxes. From raw material verification to final shipment, our quality control system is designed to:

• Prevent defects before they occur
• Maintain process repeatability across multiple batches
• Guarantee reliable performance for automotive, agricultural machinery, industrial equipment, and heavy-duty applications

Our step-by-step QC workflow ensures every casting undergoes strict, traceable inspections from raw material analysis to final validation, including:

• Spectrometer chemical analysis for alloy verification
• Sand testing, pattern & core inspections before molding
• Melt temperature control & real-time alloy adjustments
• Controlled cooling cycles & defect detection protocols
• CMM-based machining inspections with full PPAP documentation
• Final dimensional, tensile, hardness, and surface roughness checks

Our in-house metallurgical laboratory supports the QC process with advanced iron casting testing equipment, enabling precise measurements and material analysis:

• Optical Emission Spectrometer (OES) – real-time chemical composition analysis
• Coordinate Measuring Machine (CMM) – micron-level dimensional checks
• Universal Testing Machine – tensile & yield strength testing
• Brinell and Rockwell hardness testers – hardness verification
• Metallurgical microscope – microstructure & graphite analysis
• Impact testing machine – toughness & performance under stress

Our custom iron casting quality control framework is a fully integrated quality management system combining:

• ISO 9001:2015 procedures
• PPAP documentation for OEM traceability
• Real-time process monitoring
• Advanced inspection technology

OEM Benefits:

• Defect Prevention – Eliminates flaws before shipment
• Process Consistency – Repeatable results across production batches
• Compliance – Meets IATF 16949, ASTM, and other global standards
• Faster Turnaround – Lower scrap rates shorten lead times
• Traceability – Full QC documentation from foundry to final assembly
