The trend of precise and diverse fins has resulted in thinned-drawn fin, arc fin, ellipse tube fin, flat tube fin, etc. The technical innovations of thin material forming, small hole drawing, higher burring, multi-diameter combination, and the implementation of 400~800spm punching rate and smart automation have raised higher challenge towards the fin die's parameters of heat exchaning technology, accuracy and stability. Such a seemingly easy innovation requires the most complicated technology to guarantee precision. Wuxi Micro Research can provide customers with one-stop service including products designing, die manufacturing, assembling, test running and mass production. As for heat exchanging fin patterns, we can achieve diversified fins with holes diameter ranging from 4.0mm to 25.0mm .
