Customer: A third-party testing laboratory providing packaging validation for export manufacturers in the Pearl River Delta.

Challenge: The lab needed to extend its scope from basic compression testing to full GB/T 4857 and ISTA series procedures, with calibrated, audit-ready equipment.

Solution: Electronic box compression testers (DY-3210 series) for stacking and crushing strength, plus single-arm drop test machines (0.3-1.5 m) for free-fall drop validation, all delivered with calibration certificates.

Result: The lab passed its scope-extension audit and now offers one-stop compression + drop validation. Machine uptime has remained stable with routine maintenance provided by Dongyang service engineers.
