Haifeng Automation Overall Solution for Safety Shoes
Industry Pain Points
Volatile protective performance
Traditional production relies on manual operations, with a lack of precise control over raw material proportioning and molding processes. Core protective indicators show high dispersion, and most products fail to meet standards such as GB 28011-2019 and EN ISO 20345, posing potential safety hazards.
Unbalanced durability and comfort
The bonding process between the upper and sole is underdeveloped, leading to frequent delamination, cracking, and premature wear. Improper matching of material hardness and elasticity causes workers to easily feel fatigued after long-term wear, affecting work efficiency.
Heavy pressure on environmental compliance: Traditional solvent-based processes result in excessive VOC emissions and residual harmful substances such as formaldehyde, exposing enterprises to environmental penalties and making it difficult to enter high-end labor protection markets in Europe and America.
Low R&D and production efficiency
The development cycle for molds of new styles is long, with low fault tolerance during small-batch trial production. Mass production involves fragmented processes, with raw material waste exceeding 15%, high labor costs, and slow market response.
Core of the Solution
Haifeng Automation, a veteran in the polyurethane automation equipment industry, focuses on the core demands of “comprehensive protection, long-lasting durability, green environmental protection, and intelligent efficiency”. It integrates independently accumulated solvent-free/water-based PU technology, precision manufacturing processes, and intelligent quality control systems, integrating core equipment and process solutions into the entire industrial chain of safety shoes. Leveraging technical experience in PU foaming equipment, precision metering systems, and other fields, it achieves four core goals, adapts to multi-scenario needs, and provides integrated “technical solution + equipment implementation” services.
