All machines in the manufacturing line for the products devised and designed by engineers who have years’ experience and know-how in their own field. Casting Tape Machine, Cast machine, Air-dry System devised on revolutionary idea and design work astonishingly efficient way. For example, Back Tape Machine works 5 ~ 10 times faster than conventional raschel knit machine and Air-dry System needs no electricity as long as compressed air is supplied. And with new concept adopted, Cast machine and Splint machine are designed to perform efficient and cost-saving way. Through years’ of R & D, company succeeded developing its own Polyurethane Resin System - esp. Lubricant (Surfactant) System, which is applied to Robo Series. Company is preparing to apply for the world patent. Among manufacturers in Korea, S & F is only one who has full producing line - Polyurethane Resin, Backing Tape, finally Cast and Splint. Its technology and know-how overall line will be crucial measures in view of global business - joint venture, local plant, etc.
