Why Partner with HJTC
Tailored Cooling Engineering to Power Your Next-Gen Performance.
5,000+ Models, One Trusted Source
With over 5,000 production-grade radiator models covering passenger, commercial, off-highway, and agricultural vehicles, HJTC offers the broadest product portfolio in the industry. New models are developed at a rate of 30-50 per month to respond to changing platform requirements.
APQP-Driven Quality from Prototype to Mass Production
HJTC follows the full APQP design and development process—from DFM and FMEA through PV testing and PPAP submission. Every radiator is 100% leak-tested with helium detection (leak rate controlled at ≤50 ppm) before shipment.
Scalable Manufacturing with an Annual Capacity of 3 Million Units
6 dedicated production lines, 680 skilled employees, and a 100,000m² manufacturing campus. Daily output capacity reaches 2,000+ radiator cores, supporting everything from small-batch prototyping to large-scale OEM production.
Tailored Thermal Solutions for Every Vehicle Class
From daily commuters to heavy-duty workhorses—each application environment demands a dedicated cooling approach. We engineer radiators and heat exchangers that match the thermal load, space constraints, and durability requirements of your specific vehicle platform.
An Engineering-Driven Radiator Manufacturing Partner
HJTC works with OEM customers from the design phase. Using APQP project management, we analyze thermal requirements, structural constraints, and cost targets to deliver application-optimized radiators. DFM, CFD thermal simulation, and performance validation are integrated into every development cycle.
Trusted by OEMs and Aftermarket Partners Worldwide
Proven thermal performance, stable quality, and reliable long-term supply across passenger, commercial, and off-highway applications.
“HJTC helped us shorten our radiator development cycle by nearly 40%. Their APQP-driven process and in-house testing capabilities gave us confidence to move from prototype to mass production without delays.”
“We switched to HJTC for our off-highway radiator line—two years now with zero quality incidents. The 100% helium leak test and full traceability system were key factors in our decision.”
“The breadth of their product portfolio matters. One partner, 500+ models across our passenger and light truck platforms. HJTC delivers consistent quality, competitive pricing, and reliable lead times.”

Frequently asked questions
HJTC manufactures brazed aluminum radiators, mechanical assembly radiators, and tube-and-fin radiators covering passenger cars, commercial trucks, construction equipment, and agricultural vehicles—over 5,000 production models in total.
Yes. HJTC has a full APQP design and development process with in-house tooling, simulation, and testing capabilities. We develop 30–50 new products monthly and support OEM customers from concept to mass production.
HJTC is IATF 16949 certified. Every radiator undergoes 100% helium leak testing (≤50 ppm) before shipment. Our lab supports salt spray, vibration, thermal shock, pressure cycling, and cleanliness testing.
Lead time depends on complexity. A typical custom development cycle—from DFM through PPAP—ranges from 8 to 16 weeks. Existing production models can ship within 2–4 weeks depending on order size.
