In composite material industry, such as aviation, navigation, sports, medical lightweight material area, the digital cutting solutions are widely applied to cut carbon fibers, glass fibers, aramid fibers, asbestos fibers and so on. Compared to traditional cutter’ cutting method, SINAJET digital cutter has powerful active circular knife cutting solution, no overcut, no need to cover film, no need to spread paper under fabric, low energy consumption, cutting speed is 1500mm/s, the whole cutting table no blind zone. The cutting process and result become intelligent, precise, stable and efficient. Meanwhile, SINAJET heavy-duty auto feeding devices solved the problem to send over weight material to the digital cutter.
