1. Description of Our China Corrugated Radiator Machine Factory
1) The SPCC coil is decoiled from the hydraulically controlled expandable decoiler.
2) And after a simultaneous coil cleaning process, fed forward into a CNC controlled automatic fin folding 

3) The corrugated radiator are produced simultaneously and are sheared off by the combined cutting and edge 
bending units. 

4) The corrugated radiator and then fed into the CNC controlled welding machine for the fin edges. 
5) After the seam welding on the edges, rectangular strips are spot welded underneath the fin walls to provide 
greater stability and strength to the panel. 

6) The corrugated radiator with embossed channels, which provide greater stability to the corrugated fins, are 
then spot welded before the final bending station for 90 degrees downward bending for the two edges of the
