Outline of Final Research Achievements

A novel multimaterial injection molding using an intermediate layer has been designed. The additional intermediate layer (IML) assures a sufficient adhesion of dissimilar thermoplastics as well as to compensate mechanical and thermal stresses. Higher joint strength of dissimilar thermoplastics is probably provided by this technology due to the adjustment of intermediate layer. The goal of this work is development of the multimaterial injection molding. The results of this work indicate that the weld strength increases by using our novel multimaterial injection molding.
