In the automotive, but also in the furniture industry, there is a growing demand for decorated mouldings. Very often textile materials, which can be damaged during production, are used for the decoration. Injection compression moulding can be a mean to decrease cavity pressure during the filling phase, which is responsible for textile material damage in in-mould surface-decoration. Practical experiments were conducted comparing conventional injection moulding and injection compression moulding in respect to pressures and the quality of in-mould surface-decorated parts. The injection compression moulding process shows a strong reduction of pressure compared to conventional injection moulding. In addition the stress time, which is defined as the time, during which the decoration material is loaded with pressure and high temperatures, showed a significant influence on the quality of in-mould surface-decorated parts. With same stress times for both processes it was possible to improve the parts quality using injection compression moulding.
