Full-Process Quality Control · Rigorous Checks at Every Stage

  • Raw Material Inspection

    Chemical composition and mechanical properties of pig iron, scrap steel, and alloying elements are tested to ensure material compliance with customer specifications.

  • Pattern & Mold Inspection

    Patterns and molds are checked for dimensional accuracy, surface finish, and proper gating system design before casting begins.

  • In-Process Casting Inspection

    During casting production, we monitor pouring temperature, cooling rate, and shake-out time to prevent defects such as porosity, shrinkage, and cold shuts.

  • Machining & Surface Treatment Inspection

    After CNC machining and surface treatment, parts undergo dimensional checking, surface roughness testing, and visual inspection.

  • Final Dimensional & Performance Testing

    Finished components are subject to final inspection including hardness testing, pressure testing (for PED parts), and full dimensional report generation.

100% Quality Guaranteed

All castings that do not meet dimensional or material specifications are identified and rejected through our quality system. Non-conforming parts are either reworked where possible or scrapped, ensuring only components that fully comply with customer drawings and certification requirements leave our factory.
