As the development of new energy vehicles (NEVs) accelerates toward lightweighting, integration, and high efficiency, the automotive die-casting sector has reached a critical juncture for technological evolution; traditional multi-piece die-cast components can no longer meet the core requirements of NEVs for high thermal efficiency, high integration, and high stability. Dongguan Ouyi Precision Manufacturing Co., Ltd. specializes in aluminum alloy die-casting and precision machining, focusing on the R&D and production of core NEV components. The company has achieved breakthroughs in core technologies for the structural integration of NEV PTC die-castings. Through continuous R&D investment and technological innovation, Ouyi overcomes the limitations of traditional die-casting processes, helping to enhance quality and efficiency across the NEV industry.
In NEV thermal management systems, the PTC heating system is a critical module ensuring reliable cold-weather starts, cabin temperature control, and stable battery operating temperatures. As the core structural and thermal-conductive component, the PTC die-casting’s structural precision, thermal conductivity, and structural strength directly determine the system’s operational stability. Traditional PTC die-castings often rely on multi-piece assemblies, suffering from industry-wide pain points such as numerous weld seams, large assembly tolerances, uneven heat conduction, high failure rates, and insufficient lightweighting. Ouyi Precision has targeted the structural integration of PTC die-castings by optimizing die structures, upgrading high-pressure die-casting processes, and redesigning product architectures to transform multi-component assemblies into single, integrated units.
This integrated die-casting technology eliminates complex welding and assembly steps, allowing for the one-shot casting of multi-functional features—such as heat dissipation fins, mounting bases, retaining clips, and sealing structures. This effectively avoids assembly errors and risks associated with weld fatigue, resulting in superior structural rigidity, more uniform heat conduction, and enhanced sealing performance. Simultaneously, it significantly reduces component weight, perfectly aligning with the lightweighting requirements of NEVs. Compared to products made via traditional processes, Ouyi’s integrated PTC die-castings offer higher precision, greater stability, and superior heat dissipation efficiency, effectively boosting the overall energy efficiency of NEV thermal management systems and reducing energy loss.
Leveraging mature aluminum alloy die-casting processes and continuous technological evolution, the company produces PTC die-castings, general NEV parts, and control box components that are widely compatible with various NEV passenger and commercial vehicle models. Leveraging its core technological advantage in the structural integration of PTC die-castings, Ouyi Precision effectively enhances its market competitiveness. The company provides high-precision, highly integrated, and highly reliable die-casting solutions for the new energy vehicle industry, helping automakers achieve upgrades in component lightweighting and integration.
