Our Malaysian customer carried out factory acceptance inspection at our workshop. Upon client’s request, we manufactured both large and small corrugated fin test samples to check the forming quality and capacity of the corrugated fin forming machine. This machine is fitted with coil feeding trolley and auxiliary working platform. Its processing range covers wave width 300–1600 mm, wave height 50–400 mm and wave pitch over 40 mm. The sample forming test went smoothly and satisfied our customer.
