Precision with every milligram
Micro Injection Molding
With molded part weights from 1 to 10,000 milligrams, we serve a wide range of different part requirements in micro injection molding. Our extensive experience in one and two component injection molding technology, vertical micro injection molding and with a wide variety of materials enables application-oriented solutions of the highest quality from feasibility studies to series production. In injection molding it is important to plasticize only the smallest amounts of plastic in order to avoid thermal stress on the plastic melt, and then to inject these into the cavity with the highest precision. At this point, the screw-piston principle used up to now reaches its limits. The reason for this is that the diameter of the screw piston cannot be optimally adapted to small shot weights for mechanical stress reasons.
The KUZ developed a machine technology specially adapted for micro injection molding based on the principle of 2 piston plastification. The consistent design of the injection unit for very small shot weights, in conjunction with a servo-electric injection drive, makes it possible to control the filling phase for micro parts and thus increase the precision of the molding. This machine and mold concept makes it possible to design very small gating systems, so that shot weights down to 10 mg are no problem. This is complemented by a master mold concept that minimizes costs and effort.

Rheology and thermal analysis
The description of the material properties of plastics is essential for the design of processing procedures and for quality assurance. Rheometric investigations can be used to characterize the flow and deformation behavior of thermoplastic polymers and to better understand their structure-viscosity behavior during processing. The test methods of thermal analysis open up the possibility of identifying relationships between processing conditions, microstructure and material properties of plastics. In this way, polymers can be identified and processing-related material damage can be detected. In this seminar, the theoretical fundamentals of rheology and thermal analysis are combined with practical demonstrations of the equipment in the laboratory and pilot plant. Concrete application examples from the practice of the accredited testing laboratory at the KUZ will be used to show what information can be obtained from the recorded measurement curves.

Plastic innovatively shaped
Injection molding, along with other major plastics processing methods, is one of the most widely used primary molding processes.
The speed at which new trends lead to changing customer wishes and new products and innovations is constantly increasing. New developments of corresponding materials are expensive and not always necessary. To ensure that you remain flexible and can actively respond to changing requirements, the modification of existing plastics with appropriate additives is an option.
