Precision-engineered heat exchangers, EV battery cooling plates, aerospace stamping dies, and custom intercooler pipes designed for extreme industrial applications.
Addressing modern thermal management challenges across automotive, renewable energy, and heavy industrial sectors worldwide.
Global automotive tier-1 suppliers and aftermarket distributors demand robust aluminum radiators, parallel flow condensers, and oil coolers designed to withstand extreme thermal stress, vibrational fatigue, and corrosive environments.
With the rapid electrification of transport, electric vehicle (EV) manufacturers require specialized high-voltage LiFePO4 battery pack cooling plates, liquid thermal jackets, and precision stamping dies that guarantee optimal operating temperatures.
Industrial machinery, marine navigation, sugar processing units, and large-scale VRV air conditioning systems depend on high-frequency welded finned tubes and multi-channel heat exchangers for continuous, failure-free operation.
Pioneering the next generation of thermal innovations through advanced metallurgy, simulation-driven design, and sustainable manufacturing.
Transitioning toward micro-channel multi-port extruded (MPE) aluminum tubing and controlled atmosphere brazing (CAB) furnaces to achieve superior heat transfer efficiency while reducing overall component weight by up to 30%.
Leveraging Computational Fluid Dynamics (CFD) and finite element analysis (FEA) during the R&D phase to accurately simulate thermal dissipation profiles, fluid pressure drops, and structural longevity before physical tooling.
Integrating closed-loop aluminum recycling protocols, energy-optimized stamping lines, and eco-friendly surface passivation treatments to meet rigorous international corporate carbon reduction mandates.
Global reach backed by rigorous international certifications, multilingual engineering support, and dependable logistics execution.
As an ISO/TS 16949 certified enterprise, Zhejiang Rock Auto enforces strict quality gates throughout raw material inspection, automated core assembly, helium leak testing, and vibration testing to ensure zero-defect delivery for global industrial clients.
We provide comprehensive OEM/ODM custom prototyping services with dedicated multilingual engineering project managers, secure export packaging, and flexible supply chain management tailored to North American, European, and Asian markets.
Expert insights into our manufacturing capabilities, customization workflows, and technical standards for global B2B procurement partners.
Our MOQ varies depending on the product complexity, tooling requirements, and raw material specifications. For standard catalog items like radiator tubes or condensers, we offer flexible batch sizes. For custom EV cooling plates or stamped dies, our project team collaborates closely with clients to establish viable pilot run quantities.
We operate under strict ISO/TS 16949 quality management protocols. Every manufacturing batch undergoes advanced testing procedures, including high-precision dimensional optical scanning, helium leak testing, burst pressure evaluation, and salt spray corrosion resistance testing.
Yes. Our dedicated R&D department utilizes state-of-the-art CAD and CFD simulation tools to assist global clients from initial concept design and material selection (such as AL6061, copper, and specialized alloys) to rapid prototype tooling and full-scale manufacturing.
Standard prototype and sample development typically take between 15 to 25 days depending on tooling complexity. Mass production export orders generally require 30 to 45 days, backed by secure, export-grade packaging and reliable international freight logistics.
