A new flexible forming technique for thermoplastic polymer: multi-point thermoforming (MPTF) was developed. Polycarbonate (PC) is a typical thermoplastic polymer exhibiting many properties ideally. The material parameters of PC according to Mooney-Rivlin hyperelastic constitutive model were determined based on the high temperature tensile test data. The commercial software Abaqus was utilized to simulate the MPTF process of PC sheet. A series of numerical simulation results show that the best combination of forming temperature and forming pressure for PC sheet are 160℃ and 10kPa, respectively. MPTF experiments were carried out under the processing parameters which were determined by numerical simulations and the simulation results were validated by comparing them with the experimental results. The spherical and saddle-shape parts formed by MPTF were measured using a 3D sensing system and the measured data were compared with the target shape to analysis the accuracy of MPTF. The comparison results show that the formed parts have good accuracy.
