Explore our core catalog of critical components spanning high-temperature superalloys, advanced thermal barriers, electronic sensing, and robust chassis control systems.
Established in the automotive powerhouse of Guangzhou, Guangdong Province, in 2011, Guangzhou Mayumi Auto Co., Ltd. has grown to become an authoritative partner in the design, engineering, and manufacturing of precision vehicle assemblies. Over the past decade, we have transitioned from traditional Internal Combustion Engine (ICE) support mechanisms into a Tier-1 and Tier-2 supplier for the rapidly transforming global Electric Vehicle (EV) and hybrid ecosystems.
Operated within a state-of-the-art 25,000 square meter modern production facility, our enterprise harnesses the mechanical acumen of over 280 skilled personnel, including an in-house engineering and R&D division dedicated to high-precision design, metal stamping, complex tool-and-die execution, and metallurgical analysis. From structural components to active electronics integration, we ensure that every module adheres to the most demanding international safety and performance protocols.
Our quality assurance system integrates physical validation methods, including 3D coordinate scanning, ultrasonic non-destructive testing, and high-frequency fatigue tests, meeting stringent IATF 16949 standards.
The shift toward vehicle electrification alters physical requirements, structural load limits, and thermal dynamic envelopes.
Modern high-voltage batteries run at elevated thermal states during rapid DC charging. High-density, high-resistance insulation—such as precision mica components—is essential to construct thermal runoff firewalls, ensuring safety and protecting electronics.
Because battery packs introduce significant weight, minimizing component mass is critical. Utilizing lightweight custom aluminum die castings and metal-spun accessories offsets battery mass, helps extend range, and optimizes vehicle weight distribution.
Without the masking sound of an internal combustion engine, electric vehicle cabins are sensitive to road noise, harshness, and suspension vibrations. This makes precision suspension parts, active links, and quiet-running bushings vital for passenger comfort.

At Guangzhou Mayumi Auto Co., Ltd., we support the production lifecycle from initial concept and rapid prototyping to volume manufacturing. Understanding the demands of global supply chains, our factory utilizes automated production cells, precision casting systems, and computerized control loops to maintain consistent quality.
Our casting processes involve high-purity aluminum alloys, nodular cast irons, and superalloys. For instance, in manufacturing turbocharger accessories or high-stress brackets, components like the GH4080A superalloy are selected for their oxidation resistance and high mechanical strength at elevated temperatures.
To ensure part accuracy, each manufacturing stage is closely monitored. Optical spectrometers analyze alloy compositions, while 3D Coordinate Measuring Machines (CMM) verify dimensional tolerances. Standardized barcoding is also used to track production lots back to the raw material stage.
A inside look at our 25,000 square meter facility, testing laboratories, and automated manufacturing lines.
Our long-term engineering focus supports high-voltage architectures, vehicle-to-load integration, and structural safety modifications. As global OEMs transition from 400V to 800V drivetrains, thermal dissipation demands will increase, making advanced insulating materials and lightweight structural chassis parts critical.
Our thermal and insulating solutions are designed to handle the high switching frequencies and operating temperatures of SiC-based traction controllers, helping minimize electromagnetic interference and thermal stress on adjacent components.
High-voltage battery packs require durable, fire-resistant barriers. Our range of customized structural mica barriers protects adjacent modules, preventing propagation in the event of cell thermal runaway.
We are expanding our product line to include active components for adaptive suspension setups, helping balance ride dynamics and chassis control in heavy battery-laden EVs.
Exporting to Europe, North America, South America, the Middle East, and Southeast Asia requires adherence to diverse regulatory frameworks. Mayumi Auto maintains full compliance across global logistics pipelines, manufacturing standards, and chemical regulations.
Our parts comply with key chemical, environmental, and safety regulations, including RoHS, REACH, and California Proposition 65. Each batch of parts is provided with standard compliance certifications to ease importation and regulatory checks at international borders.
Located near major shipping ports in Guangzhou, we offer flexible shipping arrangements (FOB, CIF, DDP) to fit global supply chain schedules. By using optimized shipping routes and logistics hubs, we help support Just-In-Time (JIT) manufacturing and reduce lead times.
