Non-foaming dilatable materials are provided at suitable locations in the mold, such as the steering support cavity, the pedal support cavity, the seat stay butting cavity and the chain stay butting cavity. By heating the mold once, the seat stays and chain stays will secure with the front triangle and the front triangle can be cured at the same time to simplify the mold and the process.Field of SearchOne component is a fibrous or textile sheet, web, or battJoining a plurality of superposed fibrous or textile layers Utilizing a flexible, deformable, or destructable molding surface or material Utilizing fluid-expansible mold Frames and running gear With fluid pressure to prevent collapse of hollow structure during assembly and/or joining In configured mold | |
