Haifeng Automation Overall Solution for Shoe Soles
Industry Pain Points
01
Insufficient Core Performance and Quality Stability
The wear resistance, slip resistance, impact resistance and other core performance of traditional shoe soles are weak, failing to meet safety requirements under complex road conditions. Meanwhile, reliance on manual proportioning and inadequate process control lead to significant performance variations among products of the same batch and a high defect rate.
02
Intense Pressure on Environmental Compliance
Solvent-based production processes emit excessive VOCs, making it difficult to meet the environmental access requirements of European and American markets and severely restricting market expansion.
03
Imbalanced Production Efficiency and Costs
Fragmented production links and high labor dependence not only cause over 15% of raw material waste, but also limit production capacity release, resulting in difficulty optimizing efficiency and costs.
Core of the Solution
With years of experience in polyurethane equipment manufacturing, Haifeng Automation centers on “robust performance, stable quality, green compliance, and efficient mass production”. Leveraging independently developed core equipment such as automatic disc polyurethane casting machines and single/double-density molding systems, we have created a full-process solution covering material R&D, automated molding, and quality verification. This solution achieves the core goals of “wear resistance, slip resistance, environmental friendliness, and high efficiency” for shoe soles, adapts to the needs of various shoe types, and provides integrated “technology + equipment + operation and maintenance” services.
Core Solution Modules
R&D of High-Performance and Environmentally Friendly Materials
Scenario-specific formula customization: Relying on Haifeng’s polyurethane R&D capabilities, we develop customized solvent-free/water-based PU formulas, adding functional ingredients based on shoe type requirements. We precisely adjust hardness (Shore A 55-85) and tear strength (≥30N/mm) to meet core performance standards.
Material performance optimization: Formula compatibility is verified through Haifeng’s test platform to ensure stable wear resistance, slip resistance, and other properties. With mold optimization experience, we avoid defects such as bubbles and uneven density.
Automated Precision Molding Production
Full-process intelligent production line
Equipped with Haifeng's automatic disc polyurethane casting machine (supporting multi-mold cycle operation), it features precise metering (≤±0.8% accuracy), high-pressure foaming (18-22MPa), real-time monitoring of key parameters, and full-process automation.
Customized mold and process adaptation
Supports single/double-density molding, provides customized molds, and quickly responds to personalized needs.
