Invisible Passenger-side Airbag (IPAB) door system must be designed with a weakened area such that the airbag will break through the Instrument Panel (IP) in the intended manner, with no flying debris at any temperature. At the same time, there must be no cracking or sharp edges at the head impact test (ECE 21.01). Needless to say, Head impact test must keep pace with the deployment test. In this paper, we suggested soft airbag door system that is integrally molded with a hard instrument panel by using Two-shot molding. First of all, we set up the design parameters for the optimal deployment and head impact performance of IPAB door by CAE analysis. And then we optimized the molding condition by controlling the open-close time at each gate of the mold. We could keep the boundary of two materials by making gate-time controlled through resin temperature sensor.
