Double diaphragm forming
WebSolvay has developed a novel forming technology called Double Diaphragm Forming (DDF). This method automates dry fiber pre-forming, prepreg pre-forming or press molding into a single-step process speeding up the takt time involved in part making. WebMar 16, 2024 · Forming process constraints such as those given by diaphragms in double diaphragm forming (DDF) or by blank holders in punch forming, deep drawn and die (such as that in RTM process) can be easily captured by commercial FEA software with minimum manual interventions (Rashidi et al., 2024b). FEA-based modelling is however more …
