Why Chemical Foaming Molding Simulation?
Chemical Foaming Molding (CFM) is a molding process that full-fill the cavity with gas produced by chemical reactions. Polyurethane (PU) foam molding is the most common molding process in chemical foaming molding. According to its mechanical properties, PU foam products can be divided into two categories: rigid and flexible foam. Rigid foam cannot be reinstated under deformation, but flexible foam have the ability to their original state after apply a deformation. Polyurethanes can enables manufacturers to reduce weight, save cost, increased comfort, resist corrosion, insulate heat, and absorb sound.
Challenges
- Difficulty of processing control (control of state of thermodynamic instability)
- Unknown of foaming process (temperature and pressure variation)
- Development of reliable CAE technology
