The Transformer Radiator Panel Roll Forming Machine is the core forming equipment used in transformer radiator manufacturing lines.
It is designed to continuously process steel coils into corrugated radiator panels through automatic feeding, roll forming, leveling, length measurement, and hydraulic cutting operations.
The machine integrates roll forming, end forming, punching, and cutting functions, producing radiator panels with consistent dimensions and stable quality for subsequent turnover joining, multi-point welding, and seam welding processes.
With automatic control and high forming accuracy, this equipment helps transformer manufacturers achieve efficient radiator production, reduced manual operation, and improved manufacturing consistency.
| Panel width
300 – 535 mm |
Centre distance
400 – 4,000 mm |
| Centre distance error

The machine combines radiator panel forming, end forming, punching, and cutting functions into one production unit, reducing additional processing steps.
The roll forming system ensures stable corrugation shape, accurate dimensions, and consistent radiator panel quality during continuous production.
The system uses automatic length control and hydraulic cutting technology to produce radiator panels according to preset specifications.
Through PLC and touchscreen control, operators can easily set production parameters, improving automation level and reducing manual intervention.
The Transformer Radiator Panel Roll Forming Machine is installed at the beginning of the radiator manufacturing process, after steel coil feeding and before panel turnover and welding operations.
The typical production sequence is:
Steel Coil Feeding → Automatic Decoiling → Radiator Panel Roll Forming (End Forming / Punching / Cutting) → Panel Turnover & Joining → Multi-Point Welding → Double-Side Seam Welding → Edge Trimming → End Welding → Leveling → Automatic Cutting & Unloading → Header Pipe Assembly
During this process, the machine converts flat steel strips into finished radiator panels with required oil channel shape, length, and dimensional accuracy.
It provides the essential forming foundation for the following assembly and welding processes.
