 the Sand Mold

      No-bake sand molding can meet the baseline requirements
        for the connector for surface finish, detail level, and cost.  It
        actually has slightly better numbers than green sand for surface finish. 
      The key issue is that no-bake sand molding can hold
        tighter dimensional tolerances at larger dimensions than green
        sand.  It meets the target tolerance of 2.6 mm for the larger
        dimension. |
