Get Your Radiator Factory Running — Without the 3-Year Learning Curve
Since 2012, ChangHeng has delivered more than 60 sets of heat exchanger and radiator production equipment to factories in more than 30 countries. From a fin machine to the turnkey project of the whole production line, we only do one thing: let your production line be put into production successfully at one time.
15 Years, Starting With One Fin Machine
ChangHeng was founded in Quzhou, Zhejiang, in 2012. We started with one goal: build fin machines accurate enough that customers never had to rework a part.
Our first customers were start-up radiator factories in the Middle East and South America. They could not afford European equipment, yet could not risk their output on the stability of a cheap machine.
15 years on, our machines cover every stage of radiator, condenser, intercooler, oil cooler and plate heat exchanger production. One thing has not changed: we measure ourselves by whether a customer comes back for their next line.
From a Single Machine to a Complete Line
Buy one fin machine, or hand us the whole new factory. We do both — with the same attention.
Single Machines
Fin punching and rolling machines, continuous and vacuum brazing furnaces, tube expanders, crimping machines, fin molds and progressive dies.
Every machine is test-run at full load before shipping, and ships with a commissioning report.
Complete Lines
We size every station — fin forming, brazing, assembly, leak testing — to your product, output target and floor space.
So no single machine becomes the bottleneck of your line.
Technical Service
Selection consulting, installation, operator training, long-term spare parts supply, repair service, and cost-effective second-hand options.
One-year warranty on every machine; technical consulting is free.
We Don’t Compete on Price. We Compete on Your Total Cost.
“The lowest price is not our goal. Giving you reliable capacity at a fair cost is the most honest return we can offer.”
Engineers Who Ran Real Lines
Our engineers come from the cooling industry itself, averaging 15+ years. They understand what you mean, Any details about radiator and heat exchanger
One Supplier, One Delivery
Fin machine to brazing furnace to leak tester — one negotiation, one delivery, one commissioning. No juggling five suppliers.
Spare Parts in Stock
Common machines and wear parts are kept in stock. One-year warranty on every machine; operator training and technical consulting are free.
Sized to Your Budget
We design to your budget and payback period — not to our most expensive model. When budgets are tight, we recommend quality second-hand machines.
Three Rules We Don’t Bend
Skills can be taught. Standards cannot be traded away. These three rules apply to every project we take.
No Machine Ships Untested
Every machine completes a full-load test run and ships with a commissioning record.
No Capacity You Won’t Use
Output and precision are specified to your actual need. We don’t sell the surplus.
Delivery Is Not the End
Installation, training, spare parts and repair — we stay for the machine’s whole life.
Tell Us About Your Factory. We’ll Design the Line
You don’t need to pick a machine first. Tell us your product, target output and floor size, and we will send a proposal with the machine list, layout suggestion and payback estimate — free, and without a follow-up call barrage.
