Customer Background<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Based in Phnom Penh, Cambodia, the client has 6 years of experience in R&D and production of PU comfort insoles, shock-absorbing insoles, and safety shoe insoles. It mainly supplies export-oriented shoe factories in Cambodia, Vietnam, and Thailand, and its products must meet EU environmental and quality standards for export.<\/p>

The factory used old low-pressure foaming equipment relying on manual proportioning and adjustment, resulting in poor product consistency and lack of data traceability, making it difficult to pass customer factory audits.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Project Overview<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

A professional PU insole manufacturer in Cambodia was troubled by uneven foaming, unstable temperature control, inconsistent hardness, poor resilience, and low batch consistency due to outdated semi-automatic equipment. These issues made it difficult to meet the quality and audit requirements of export-oriented shoe factories in Southeast Asia.<\/p>

Haifeng Automation provided a dedicated lightweight upgrade solution for insoles, equipped with 2 sets of Haifeng XJJF Series Precision PU Foaming and Pouring Machines, combined with constant-temperature mold stations and formula management functions. The low-cost intelligent transformation helped the factory quickly improve quality, efficiency, and delivery capacity.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
