More than 90% of our FRP products are hand paste production, other molding, winding, laminating method, etc.. Japan's hand paste still accounts for 50%. From the world, hand paste still accounts for a considerable proportion, indicating that it still has vitality. Hand paste method is characterized by wet resin molding, equipment is simple, less cost, one can paste more than 10m of the whole product. Disadvantages are low mechanization, long production cycle, unstable quality. China has introduced extrusion, spraying, winding and other process equipment from abroad, with the development of FRP industry, the new process will continue to appear.
