Hi all, According to DIN and IS standards, springs made from wire or rod with a diameter above 16 mm should be hot coiled due to specific reasons. We have consulted with several manufacturers who claim they can cold coil springs using wire or rod up to 30 mm in diameter. Could you please advise if springs made from wire with a diameter ranging from 16 mm to 30 mm using the cold coiling process would be as effective as those made using the hot coiling process? I look forward to your valuable suggestions. Best regards, Johny

Hi Johny. From 16mm to 30mm, you can use the cold coiling spring machine. We have another video to show the cold coiling process.
