HDBALLS maintains a dedicated quality laboratory for quality control of mass production projects. We rigorously measure and inspect each batch of products, covering characteristic parameters specified by international standards, such as heat treatment, hardness, tolerances, roundness, roughness, and crushing load.
We also provide quality control reports such as SGS, MSDS, and ROHS. For other special tests and reports requested by customers (such as raw material chemical analysis, salt spray testing, and ROHS certification), we can provide sample reports issued by third-party testing agencies. This ensures the highest quality. Our testing equipment is regularly calibrated by certified testing laboratories.
