Vertical FRP tank winding machine, as a high-tech electromechanical machine, is also designed for manufacturing winding molded tanks and vessels similar to horizontal FRP tank winding machines. However, this one fabricates vertical large-scale products from 4m to 25m in diameter on customer's site. Equipped with thermosetting resin filament roving device, it winds filament helically around the rotating mandrel accurately to ensure stable and durable products.
