Raw TPU particle materials undergo FTIR spectral analysis before production to unify chemical composition of inner and outer layers. The factory is equipped with dual-color injection molding machines, electronic thickness gauges and 3D contour scanners, controlling overall sole thickness deviation within ±0.06mm. The in-house CNAS laboratory implements rotary drum abrasion testing, repeated flex cycle testing and interlayer peeling strength testing for each batch. Low-temperature flexibility testing at -28℃ and GC-MS chemical hazard detection are conducted routinely; all batch inspection documents are archived for overseas brand audits and customs clearance.
