Testing Instruments

The company has established a comprehensive quality inspection system covering raw material incoming inspection, production process control, finished product performance verification, and exception re-inspection. Through various methods including composition testing, microstructure analysis, hardness testing, mechanical property testing, forming performance verification, and dimensional accuracy inspection, we implement full-process control over key quality indicators of aluminum circles, providing reliable assurance for stable product delivery and continuous optimization.
