Quality Control – Ensuring Reliable Aluminum Profiles
Shandong Jinchang Aluminum Industry Co., Ltd. regards quality control as the core of production management. From raw material sourcing to final product delivery, we implement full-process quality control to ensure every aluminum extrusion meets strict standards. Through a rigorous and traceable quality management system, we ensure stable product performance and reliable quality for global customers.
Raw Material Inspection
Quality control begins with strict raw material screening. We use high-purity aluminum ingots from reliable and traceable suppliers, ensuring consistent material quality for extrusion production.
● Each batch of raw materials undergoes strict inspection, including:
● Chemical composition testing
● Alloy grade verification (such as 6063 and 6061)
● Raw material certification inspection
Production Process Control
Key production processes, including extrusion, aging, and surface treatment, are controlled through automated systems. Production parameters such as temperature, extrusion speed, and pressure are monitored in real time through the MES management system to ensure process stability and consistent product quality.
In-Process Inspection
Inspection checkpoints are set at every stage of production. Random inspections are conducted to verify:
● Dimensional accuracy
● Mechanical properties
● Surface quality
Any abnormalities are immediately isolated and traced to maintain process reliability.
Final Inspection and Testing
Before shipment, all products undergo comprehensive inspections to ensure compliance with customer and industry requirements, including:
● Appearance inspection
● Hardness testing
● Coating thickness measurement
● Adhesion testing
Inspection reports can be provided to ensure product quality and traceability.
Quality Certifications
We are ISO 9001 and ISO 14001 certified, establishing a continuous improvement mechanism to ensure long-term stable supply and high-standard quality control.
