Proprietary Technology

Patented Dynamic Waterproof Footwear Testing Device

Unlike conventional factories that outsource or test only raw membranes, Tianmao operates in-house proprietary testing equipment (Authorized Patent ZL201920812345.X). Our automated rig flexes finished boots under water immersion to simulate real-world wading, detecting micro-leaks before lasting.

Key Testing Benchmark & Protocol:

✔ Testing Mode: 100% shoe water immersion dynamic flex cycling
✔ Flex Threshold: ≥ 25,000 continuous cycles without water ingress
✔ Air Pressure In-line Check: 0.03 MPa pneumatic pressure sensor
✔ Compliance: SATRA TM77 & ISO 20344 dynamic water resistance

Zero-Defect Protocol

8-Gate Quality Assurance & AQL 0.65 Standard

Every production run undergoes strict military-grade gate inspections from raw materials to container loading.

Gate 1

Inbound Material Check

Tensile strength, hydrostatic head, rub fastness, and batch color matching (ΔE ≤ 0.8).

Gate 2

Cutting & Skiving Check

Grain direction inspection, edge beveling precision, and thickness grading.

Gate 3

Seam Taping Verification

Hot-air tape adhesion on waterproof booties; 100% pneumatic air pressure testing.

Gate 4

Patent Water Immersion

Proprietary dynamic flexing in water rig. Zero tolerance for moisture ingress.

Gate 5

Lasting & Bonding Audit

Adhesive halogenation temperature, sole cement coverage, and pneumatic press pressure.

Gate 6

Cold Flex & Aging Rig

-30°C freezer chamber flex endurance and accelerated heat aging tests.

Gate 7

Needle & Metal Detection

100% of finished shoes pass through high-sensitivity 1.0mm ferrous detector conveyor.

Gate 8

Pre-Shipment AQL 0.65

Carton drop test, desiccant placement, barcode scanning, and dual-witness container loading.
