A professional manufacturer of polyurethane gaskets in Slovakia has long been troubled by four core issues: unstable product performance, poor batch consistency, non-compliance with EU environmental protection standards, and lack of production data traceability. Based on the customer\u2019s demands for high-precision molding and EU-compliant production, Haifeng Automation provided an integrated upgrade solution, including equipment replacement, process optimization, intelligent control, and environmental adaptation.<\/p>

The customer introduced 2 sets of Haifeng XJJF-3\u00d750Z70A polyurethane foaming and pouring machines and completed a full production line upgrade within 3 months, transforming from traditional extensive production to intelligent and precise manufacturing. All products fully meet EU industrial certifications and customer factory audit requirements, and have successfully entered the high-end supporting supply chains of automotive parts and light rail transit.<\/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

The customer is a local industrial seal manufacturer in Slovakia, with 12 years of experience in the R&D and production of polyurethane gaskets and shock-absorbing sealing blocks. Its products are mainly used in automotive parts, precision machinery, and light rail transit, and all products must strictly comply with EU sealing performance standards and low-VOC environmental requirements.<\/p>

The company originally operated 2 sets of outdated low-pressure foaming machines, which had been in service for a long time. As European customers continued to raise requirements for product accuracy, durability, and compliance, the original production mode could no longer adapt to market development, and professional polyurethane automation equipment was urgently needed for technological upgrading.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Unstable product performance<\/h5>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The raw material mixing uniformity of the old equipment was less than 80%, resulting in uneven cell distribution of the gaskets. The seal failure rate was 8%\u201311%, which could not meet the precision sealing requirements of European industrial customers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\t

The equipment relied on manual parameter adjustment, on-site inspection, and manual recording, leading to long molding cycles and low yield rates. The raw material ratio error exceeded 3%, and the raw material waste rate was 14%\u201317%. The entire production line required 12 operators, resulting in high labor costs and management difficulties.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

The equipment did not have a production data collection and storage function, unable to provide production traceability records, making it difficult to pass EU industrial product quality audits and customer factory inspections. It was also incompatible with low-VOC and halogen-free environmentally friendly raw materials, missing access to high-end markets.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

There was no closed-loop constant temperature control system. The temperature fluctuation during foaming and curing exceeded \u00b15\u2103, leading to obvious differences in hardness and elasticity of the same batch of products. The qualified rate of finished products was only 82%, resulting in high rework costs.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\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
