Our Radiator Production Line (or Transformer Radiator Production Line / Automatic Radiator Manufacturing Line) is a complete manufacturing system designed to produce radiator panels for oil-immersed transformers. Starting from cold-rolled steel coil, the line performs roll forming, welding, trimming, and final finishing — delivering ready-to-use radiator fins or panels for transformer tanks.

This equipment meets the needs of transformer manufacturers and radiator-component suppliers for high-quality, efficient, and cost-effective radiator production.

Typical Applications & Why Radiator Production Matters

Oil-immersed power transformers — Radiator panels produced by such lines are used to dissipate heat generated by core iron losses and copper losses in windings, enabling stable long-term transformer operation and higher load capacity.

Transformer OEMs or sub-suppliers — Companies aiming to integrate radiator production in-house rather than sourcing radiator panels externally.

Custom or small-batch radiator manufacturing — The line’s flexibility (custom widths, panel lengths, coil materials) allows customization per transformer specification.

Improved supply chain control — By owning a radiator production line, manufacturers can reduce lead time, ensure consistent quality, control cost, and respond quickly to design changes.

What a Typical Radiator Production Line Includes?

A full-featured radiator production line usually includes:

Automatic Decoiler / Coil Unwinder — Accepts cold-rolled steel coils (e.g. SPCC, ST12, DC01, etc.) and feeds strip into the forming line.

Roll Forming / Hydraulic Press Station — Forms the coil strip into radiator fins / panels. Pressing ensures proper shape, strength, and dimensional accuracy.

Panel Turning / Flipping & Matching Device — For lines that join two sheets or for double-sided welding, ensuring correct alignment before welding.

Spot Welding / Multi-spot Welding Station — Temporarily fixes parts for further seam welding.

Seam Welding Machine (Double-side / Longitudinal Welding) — Provides permanent welding for radiator panels, ensuring structural integrity and leak-proof finish. 

Edge Shearing / End Cutting / Panel Straightening / Leveling & Trimming — Final finishing steps to ensure panel edges are clean, dimensions are precise, and panels meet required tolerances.

Automatic Stacking / Conveyors / Unloading Table — For efficient output handling, stacking, storage, or further assembly into transformer tanks.

Advantages of Using a Dedicated Radiator Production Line

Using a dedicated Radiator Production Line for transformer radiators gives the following benefits:

High-quality, consistent radiator panels — precise roll forming + automated welding ensures uniform quality, leak-proof seams, dimensional accuracy, stable performance.

Cost-effective for medium to large production volumes — reduces labor costs, improves throughput, and reduces dependency on external radiator suppliers.

Flexibility and customization — can produce radiator panels of various widths, lengths, thicknesses, and adapt to different transformer designs.

Shorter lead times & supply-chain control — in-house radiator production helps OEMs respond faster to demand, manage inventory, and reduce procurement delays.

Scalability — from small batches to high-volume runs; suitable for transformer manufacturers of different scales.

Compliance and quality assurance — with proper process control (PLC, welding stations, trimming, finishing), produced radiators are more likely to meet international quality standards, ensuring reliability in transformer operation.
