The fin machine can produce different fins by changing the corresponding fin molds. No doubt, this is a big progress that saves the cost of purchasing machines when you need produce too many specification of fins. But meanwhile, machine users have to face a big problem, namely they need often replace and debug fin molds which is a skilled job. Even if for an experienced fin operator, he also has to spend 2 hours or so to finish the task. With the continuous research and development, the 3rd generation fin machine can easily adjust the fin height by control panel which needn`t spend much time by manual. This is an important milestone of fin machine development history, technology makes fin production easier. So far, the 3G intelligent fin machines have been successfully put into the market and entered into mass production period.
