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 moulding (2k 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 (computer aided engineering) method to model the 2K ICM process. Using a prototype roof, computer-predicted results have been correlated with real-life trials of the injection-compression moulding process. With new software tools that can accurately predict the moulding 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 with both wet and plasma coats.
