Introduction: Bladder molding is a specialized technique in composite manufacturing used to produce hollow or complex-shaped composite parts with intricate internal features. This method involves using a bladder or inflatable punch to apply pressure from inside a layer of composite materials, which facilitates the stabilization of the part and ensures uniform compaction and resin distribution. Bladder molding is commonly used in industries such as aerospace, automotive, marine equipment manufacturing, and sports equipment for producing components like aircraft fuselages, automotive fuel tanks, boat hulls, and bicycle frames.
