Strict Quality Control in CEX Casting

Aluminum Casting Processes Quality Control

We strictly adhere to the quality control requirements of the ISO 9001 and IATF 16949 systems for aluminum casting processes.

From raw materials to finished products, from initial samples to large-scale production, every step undergoes rigorous quality testing.

Quality Inspection of Aluminum Castings

For each batch of die casting products, we conduct mould inspection, sample inspection, and batch product inspection according to specified procedures.

Inspection Contents Inspection Methods/Instruments
Mould Dimensions Micrometer, Vernier Caliper, Full Range Pin Gauge/Gauge
Appearance Visual Inspection (Naked Eye, Magnifying Glass), Color Inspection
Material Composition Chemical Analysis, Spectral Analysis
Dimensions and Tolerances Coordinate Measuring Machine (CMM), Micrometer, Vernier Caliper, Full Range Pin Gauge/Gauge
Mechanical Properties (Strength, Hardness, Density) Tensile Testing Machine, Hardness Tester, Density Tester
Internal Structure (Porosity) X-Ray, Ultrasonic Testing, Destructive Testing, Metallographic Examination
Other Requirements Control (Pressure Resistance, Sealing Performance) Sealed Pressure Resistance Test

Control of the Production Process

Each production step follows specified operating procedures.

For the die casting process, we have established a die casting process card. We set the parameters of the die casting machine according to the requirements of the process card, and continuously monitor and record each parameter.

If any parameter deviates, an alarm will be triggered to take corrective action. This ensures the accuracy of our die casting process, thereby ensuring the qualification rate of die casting products.
