PROBLEM TO BE SOLVED: To provide an independent step pressure casting technique which can make a socket in an internal form to be completed substantially when completing a casting process, and a complete prosthesis socket of a remaining limb. SOLUTION: While a socket material is corrected, a socket material 36 which is casted preliminarily, is possible to cast, and hardened is casted by condensing pressure or simply casted. At the same time, tension is applied to a remaining limb 40 in a distal direction. As a result, a complete socket is formed so that it is fitted to the remaining limb well after correction without a substantial adjustment. A depressure structure, a socket layer, and a prosthesis coupling device 38 can be casted by condensing pressure all at once by the socket. A pressure casting system includes a pressurization chamber 20, a compression pressure application membrane 22, a tension operation system 58 which forms tension in a synthetic axial direction in the remaining limb between socket materials during the process of socket formation and hardening, and a load cell for monitoring tension in moulding and displaying it.
