Industrial Design & Engineering Development

01Industrial Design & Engineering Development

The aesthetics of shoe soles are not merely about visual appeal but critically impact comfort and functionality. Our design team utilizes a biomechanical database combined with 3D foot scanning and gait analysis to develop sole structures tailored for diverse scenarios. For instance, athletic soles employ multi-density zoning—forefoot zones (50° Shore A) for flexible rebound and heel sections (60° Shore A) for enhanced cushioning support. Anti-slip tread patterns are optimized via parametric modeling to maintain a friction coefficient ≥0.6 on both dry and wet surfaces with ensuring long-term stability and wear comfort.

02Precision Mold Technology Development

Mold precision is paramount for sole consistency. Our 5-axis CNC machining achieves cavity tolerances of ±0.005mm, while mold flow simulation software optimizes injection parameters for uniform material flow. Integrated intelligent temperature control systems limit thermal fluctuations to ±0.5°C, eliminating sink marks or warpage. For complex structures (e.g., honeycomb damping units), sliding cores and lifters ensure flawless demolding. With a service life exceeding 500,000 cycles, our molds feature real-time wear sensors for predictive maintenance, guaranteeing mass-production stability.
Formulation Science & Laboratory Research

03Formulation Science & Laboratory Research

The development of shoe sole formulas is the core guarantee of performance. We collaborate closely with renowned chemical enterprises such as LG Chemical in South Korea, along with universities and research institutes, to jointly conduct research. This enables us to provide customers with high-value shoe material solutions and differentiated services. Our laboratory uses scientific instruments to optimize formulas, replacing phthalates with eco-friendly plasticizers per EU REACH regulations. Through DMA, we adjust material damping to ensure ≥75% energy feedback, balancing cushioning and propulsion.
Engineering Prototyping

04Engineering Prototyping

Transitioning from design to physical validation requires rigorous prototyping. Our dual-density injection machines (e.g., DESMA 832) produce gradient-hardness soles—midsole with foam EVA (0.18g/cm³ density) and outsole with high-wear rubber. Prototypes endure 100,000 Ross flex cycles (ASTM D1052), while 3D scanning verifies dimensional accuracy (≤0.1mm deviation). Pilot runs simulate production-line conditions, adjusting injection pressure and cooling times to ensure manufacturability.
Standardized Laboratory Testing

05Standardized Laboratory Testing

Each batch of shoe soles must pass 20 or more tests, meeting the requirements of standards such as GB6675, EN71, ASTM F963, and C.R.C.C931. Abrasion testing (SATRA TM144) simulates 10km walking (wear volume ≤100mm³); peel strength tests (500N load) validate sole-upper bonding. Sub-zero tests (-25°C×4h) confirm crack resistance, and UV aging (300 hours) ensures ΔE≤3 yellowness index. All data feeds into MES for AI-powered quality reports. With real-time monitoring of critical parameters (e.g., hardness tolerance ±3° Shore A), we achieve 99.5% pass rates at shipment.
