Because of the difficult contact with miniaturised components not only technological and machine-technical adaptations, but also the following treatment steps must already considered with the micro inection molding production . Micro injection molding parts have connected a low weight with a surface relatively big to the mass. Beside the originating adhesive-static the electric-static forces often lead to the liability of the parts in the tool surfaces, what prevents sure dropping into the container. Against dropping, the damage or pollution speaks with micro injection molding parts in many cases also of sensitive functional surfaces. A manual use of the parts is, because of the low dimensions (the parts are not partially surely recognizable with bare eyes) and because of the delicacy of the surfaces no more possible. With the micro injection molding process, the application of using automation devices can be necessary already with unusually low numbers of micro parts. These arguments suggest that other steps of the process chain also need a use. With the need of an automation step it is logical that a manufacturing cell with assembly and quality assurance must be considered. Because of the fact that the technologies with these complexity to handle the part dimensions are expensive , the step to the automation part must be economically. The wide number of pieces spectrum asks for scalable automation solutions.
