The global automotive industry is undergoing a seismic shift toward electrification and smart mobility. At the heart of this transition lies the critical need for advanced car air conditioning and thermal management systems. As a leading China-based factory and exporter, we understand that modern cooling systems are no longer just about cabin comfort—they are about battery longevity, engine efficiency, and overall vehicle performance.
In today's volatile market, procurement directors from the EU, USA, and Southeast Asia are prioritizing supply chain resilience. Our manufacturing philosophy integrates "Factory 4.0" principles—utilizing AI-driven quality controls and automated brazing processes to ensure that whether you are sourcing high-frequency welded aluminum tubes or complete radiator systems, the reliability remains consistent. We leverage China's unparalleled industrial ecosystem to provide cost-efficiencies that do not compromise on IATF 16949 standards.
Established in 2007, Zhejiang Rock Auto Co., Ltd. has been a leading manufacturer, exporter, and supplier of high-performance auto cooling system components. With more than 15 years of industry experience, we have earned a reputation as a pioneer in the design and manufacturing of aluminum-based cooling products.
Our commitment to excellence is backed by our ISO/TS 16949 certification. We specialize in radiator tubes, intercooler tubes, oil cooler tubes, radiators, and specialized EV battery liquid cooling systems. Our state-of-the-art facility is equipped with advanced Brazing Furnaces, Fin Machines, and Core Assembly Machines.
The shift to Electric Vehicles (EVs) requires complex liquid cooling for lithium-ion battery packs. Our graphene-enhanced cooling plates are at the forefront of this technology.
Aluminum alloy is the material of choice for reducing vehicle weight and increasing recyclability. Our high-frequency welded tubes maximize thermal exchange while minimizing mass.
With "Just-in-Time" (JIT) manufacturing, we provide seamless logistics for global exporters, ensuring that car air conditioning components reach assembly lines without delay.
Utilizing Dual-Cavity Plate Fin Progressive Dies, we achieve tolerances within microns. This precision is vital for hydraulic oil coolers and intercoolers used in heavy-duty applications like shipbuilding and heavy industry.
Our R&D unit is the cornerstone of our business, conducting detailed research to improve durability. We don't just manufacture; we co-engineer solutions for Audi, Volkswagen, and Dodge Cummins systems, ensuring 100% compatibility.
Our Mission: To deliver high-quality and cost-effective cooling solutions that exceed customer expectations.
Our Vision: To be a global leader recognized for advanced technologies and environmental stewardship.
