Haifeng Automation PU Insole Production Line Upgrade - Caso do Camboja
Customer Background
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.
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.
Project Overview
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uneven foaming, unstable temperature control, inconsistent hardness, poor resilience, and low batch consistency due to outdated semi-automatic equipment.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.
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.
Core Customer Pain Points
01
Uneven Foaming & Poor Quality Consistency
Insufficient mixing performance of traditional equipment leads to uneven cell structure, obvious hardness fluctuation in the same batch, and unqualified comfort and resilience.
02
No Closed-Loop Temperature Control & Prone to Deformation
Without a stable constant-temperature system, the foaming and curing process is unstable, causing collapse, elasticity loss, and cracking of insoles.
03
High Labor Dependence & Low Production Efficiency
The production line requires 8 operators, with heavy workload in manual proportioning, machine adjustment, and trimming, accompanied by rising labor costs.
04
Low Metering Accuracy & High Raw Material Waste
Large errors in manual pouring result in a raw material waste rate of about 7%, increasing long-term production costs.
05
No Data Traceability & Difficulty Passing Audits
Without formula storage and process recording, product changeover is slow, and it cannot meet the traceability requirements of international shoe factory audits.
