    Bladder Casting

    Bladder Casting
    • Bladder Casting is an SDC developed proprietary composites manufacturing process
    • Utilizes a removable and reusable rigid mandrel to lay up complex geometry parts
    • Out-of-Autoclave manufacturing process
    • Benefits of Bladder Casting
      • Reusable tooling for multiple builds provides lower cost and shorter cycle times between builds
      • Outer and inner mold line is controlled by tooling which eliminates thickness variations and produces consistent parts reducing scrap and rework
      • Tooling is impenetrable so there is no risk of "unwashable" internal remnants which occur with washable mandrels
      • Bladder Casting can provide much higher pressures than autoclave manufacturing which improves compaction and reduces cure time
