SABIC Innovative Plastics’ Exatec* Team Opens Window to New World of Light Weight Auto Glazing with Unique Injection-Compression Molding Simulation
SOUTHFIELD, Mich. — Aug. 27, 2008 — With the latest advances in design and aerodynamics and the increasing use of lightweight materials for improved fuel efficiency, the use of transparent polycarbonate (PC) window surfaces is expected to increase in the years to come. In response to this development, two-component injection-compression molding (ICM) means lower stress and higher optical quality in PC auto glazing. Now, SABIC Innovative Plastics’ Exatec* team has created a new and unique CAE method to model the two-component ICM process. Using a prototype roof, computer-predicted results have been correlated with real-life trials of the injection-compression molding process. With new software tools that can accurately predict the molding process and the special support only available from SABIC Innovative Plastics’ Exatec team, designers will be able to achieve clearly superior lightweight glazing with Lexan* polycarbonate resin with both wet and plasma coats.
