The continuous trend towards miniaturization and multi-functional products calls for more and more multimaterial components for the future micro systems. The multimaterial and functionally integrated products are becoming in most cases an economic and technological key factor for the advanced micro systems. One of the most industrially feasible ways to produce multicomponent micro parts is the multimaterial micro moulding. By merging of shaping and assembly processes into a single step in multimaterial (also known as multicomponent) moulding, a significant economic progress can be made in micro manufacturing. This presentation will focus on the different aspects of multimaterial micro injection moulding. Special emphasis will be given to the two component micro injection moulding as this is the basic process of multicomponent micro injection moulding. The challenging task for the two component moulding is to find a material pair which fulfils the diverse requirements for the engineering application and at the same time has a reasonably good bonding and sharp interface between the two polymer materials. Many fascinating applications of two component or multi component polymer parts are restricted due to the weak interfacial adhesion and interface quality of the polymers. A thorough understanding of the factors that influence the polymer-polymer bond strength and interface quality is extremely important for the success of multicomponent moulding. The presentation focuses on the parameters that influence the quality of polymer-polymer bonding, interface and analyses the relations between the bonding and the interface quality with the special focus on micro scale applications. The results and discussion presented in this talk will provide a guideline for the multicomponent micro moulding for a wide range of industrial applications.
