Polymer Science & Mold Structural Design
The geometry of DJ-CAS-8469 incorporates Dingjian's patented anti-stress concentration groove pattern. During human gait propulsion, ground shear stress is evenly distributed across the midfoot flex channels, preventing the micro-fractures common in lower-grade commercial outsoles.
The surface is pre-treated with our proprietary plasma corona discharge and priming system, ensuring high-strength bonding with PU/EVA midsoles, strobel boards, and cement-lasting uppers without manual solvent sanding.
🧪 Quality Assurance Guarantee
Dingjian guarantees that all shipments of DJ-CAS-8469 maintain strict DIN 53516 abrasion resistance, SATRA TM161 cold crack resistance down to -20°C, and CIELAB color consistency (dE < 0.8). If any batch fails SATRA third-party testing, we provide a 100% full batch remold or credit guarantee.
