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

The enterprise is a key local manufacturer of polyurethane automotive parts in Mexico, with 22 years of experience in the R&D and production of automotive shock absorber bumpers and suspension limit blocks. It has long supplied the North American AM aftermarket. Relying on the advantages of the North American automaker’s Mexican industrial cluster, the enterprise plans to enter the OEM supply chains of General Motors, Ford and Volkswagen. The traditional equipment has hardware gaps in precision molding, fatigue stability, dimensional consistency and data traceability, which cannot meet the mandatory access requirements of IATF1949 and automakers.<\/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

As a high-end automotive bumper manufacturer in Mexico, the enterprise has long been restricted by bottlenecks such as uneven foaming, temperature control fluctuations, cumbersome model changes and no data retention, and has never been able to pass automaker OEM audits. Based on the core OEM requirements of high fatigue, high precision, multi-specification and traceability for automotive bumpers, Haifeng Automation customized four sets of LJJ series polyurethane elastic parts pouring production lines for the customer. Relying on the exclusive technical advantages of the equipment, it achieved precise mass production and stable delivery, helping the customer complete the transformation from extensive aftermarket manufacturing to high-end OEM intelligent manufacturing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Uneven mixing and large temperature control fluctuations of traditional equipment lead to bubbles and density differences inside the bumpers. The fatigue life cannot meet the OEM standard, and the bumpers are prone to cracking and failure under high and low temperature environments.<\/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
