    PRODUCTION FOLW CONTROLCONTROL

    control 1_1

    Raw Material Quality Control

    1. Strictly monitor the chemical composition, purity, and impurity levels of metal materials (e.g., pig iron, scrap steel, alloys).
    2. Conduct performance tests (e.g., permeability, strength) on auxiliary materials such as casting sand and binders.
    control 2_1

    Melting Process Control

    1. Precisely control melting temperature (avoid overheating or insufficient heating).
    2. Ensure compositional uniformity with rapid chemical analysis before pouring.
    3. Perform deoxidation and degassing (vacuum melting for critical castings).
    control 3_1

    Mold/Core Quality Control

    1. Mold dimensional accuracy must meet drawing requirements (focus on parting surfaces, draft angles, etc.).
    2. Sand compactness, moisture content, and permeability must comply with process standards.
    3. Monitor curing levels for special processes like resin sand and lost foam casting.
    control 4_1

    Gating System Design Control

    1. Scientifically design gating systems (sprue, runner, and ingate ratios).
    2. Control pouring temperature (typically 50-150°C above the liquidus line).
    3. Use appropriate pouring speeds to avoid turbulence-induced gas entrapment.
    control 5_1

    Solidification Process Control

    1. Implement directional solidification techniques (e.g., mold temperature control, chill placement).
    2. Apply progressive solidification for critical components.
    3. Monitor cooling curves against expected profiles.
    control 6_1

    Post-Processing Control

    1. Strictly manage timing and methods for sand removal and riser cutting.
    2. Standardize heat treatment (annealing/normalizing/quenching with parameter logs).
    3. Control aging treatment time and temperature.
    control 7_1

    Dimensional & Defect Inspection

    1. Full-scale dimensional inspection (100% verification of critical dimensions).
    2. Apply non-destructive testing (X-ray, ultrasonic, magnetic particle inspection, etc.).
    3. Sample tests for microstructure and mechanical properties.
    control 8_1

    Traceability Management

    1. Maintain comprehensive records per batch (heat number, operators, timestamps, etc.).
    2. Archive process inspection data and visual documentation.
    3. Establish a complete quality file system.
