Case
Application Case
We have achieved several industry-leading technologies, including ultra-thin sheet welding (plate thickness of 0.15mm), internal high-pressure forming, robotic workstation integration, and five-axis laser cutting patented systems. HEYA METAL is a long-term OEM supplier to major automakers such as Honda & Toyota.
The project was initiated in July 2005, and the development of flexible hoses began. After a series of development work including mold design, sample production, and testing & verification, the flexible pipe passed all performance tests. We were officially designated as the supplier of flexible pipe, and since then, we have obtained the qualification to supply flexible pipe to Honda.
In 2010, due to the customer (Toyota)'s localized procurement needs and the opportunity of product supply chain restructuring, the business scale gradually expanded. Cost and delivery time were unavoidable issues for Toyota. Cost reduction and efficiency improvement have always been permanent topics for the company.
In 2012, as people’s demands for automotive exterior aesthetics continued to rise, new design concepts emerged for the decorative parts at the end of automotive exhaust pipes—two exhaust decorative tailpipes of various shapes were added to the rear bumper.
In 2012, as people’s demands for automotive exterior aesthetics continued to rise, new design concepts emerged for the decorative parts at the end of automotive exhaust pipes—two exhaust decorative tailpipes of various styles were added to the rear bumper.
In April 2015, we received a request for assistance from a BYD partner. A BYD part they had taken on was scheduled for mass production in just two months, but neither its product quality nor production capacity met the mass production standards.
The project was initiated in November 2024, and the development of stage lifting frames commenced. After a series of development work including mold design, sample production, and testing & verification, the equipment passed all performance tests and obtained customer recognition. Finally, the first unit of the equipment was used at Wang Yuan’s concert in Guangzhou University Town.
