With the modules "thermoplastic plasticizing unit", "thermoset plasticizing unit" and "foam plasticizing unit", which can be combined in any way, and the possibility of integrating metal structural elements directly from the original mold, i.e. through the possibility of injection molding metallic glasses, the 2-component hybrid injection molding cell applied for offers unique freedom in hybrid process combination. This hybrid injection molding cell thus enables the combination of a wide variety of metallic, fiber-reinforced and textile, flat semi-finished products and molded or formed metal or plastic components to generate hybrid lightweight structures for a wide range of applications (e.g. high-temperature thermoplastic-metal hybrids for aerospace, shielded battery housings for electromobility, etc.), thus enabling the in-depth analysis of the process-structure-property relationships of these structures. One focus is on the hybridization of the aforementioned process routes to produce hybrid materials with comparatively large, representative surfaces. Plastics from the entire plastic pyramid (from standard thermoplastics such as PE and PP, to structural thermoplastics such as PA, to high-temperature thermoplastics such as PPS) are used as the polymeric material basis, implying a processing/mass temperature of up to 400 °C. The projected area of the samples/component plaques is to map up to 50,000 mm², which requires a clamping force of min. 4000 kN at a maximum cavity pressure of 850 bar. Other hybrid components to be used include metal sheets and so-called organic sheets. In order to be able to insert these manually in a simple manner and remove the components safely, the clamping unit will be designed vertically. To further increase the process reliability and reproducibility of the complex manufacturing process for the hybrid components, an automated handling system and feeding via a rail system is foreseen. A further requirement is the integration of a system for processing metallic glasses, which, as hybrid components, on the one hand have high mechanical properties and on the other hand - with regard to research fields of the future - allow novel material combinations. In order to increase the adhesion between the different matrix systems (thermoset and thermoplastic) with the steel/organo sheets, a preheating station is provided in the control system to ensure a smooth and coordinated overall process flow. In order to map and analyze the injection molding process parameters and the connected peripherals (e.g. handling system or preheating station), the system must be able to record measurement data, pass it on to other system components and process setting parameters. The database thus created should also be available for process and structure simulation.

凭借可以以任何方式组合的“热塑性塑化单元”、“热固性塑化单元”和“泡沫塑化单元”模块，以及直接从原始模具集成金属结构元件的可能性，即通过注射成型金属玻璃的可能性，所应用的2组分混合注射成型单元在混合工艺组合中提供了独特的自由度。因此，这种混合注塑单元能够将各种金属、纤维增强和纺织品、扁平半成品以及模制或成型的金属或塑料部件组合在一起，生成适合各种应用的混合轻质结构（例如用于航空航天的高温热塑性金属混合物、用于电动汽车的屏蔽电池外壳等），从而使 深入分析这些结构的过程-结构-性能关系。一个焦点是上述工艺路线的混合，以生产具有相对较大的代表性表面的混合材料。整个塑料金字塔中的塑料（从 PE 和 PP 等标准热塑性塑料，到 PA 等结构热塑性塑料，再到 PPS 等高温热塑性塑料）被用作聚合物材料基础，这意味着加工/质量温度高达 400 °C。样品/组件板的投影面积最大可达 50,000 mm²，这需要最小的夹紧力。最大模腔压力为 850 bar 时为 4000 kN。其他要使用的混合部件包括金属板和所谓的有机板。为了能够以简单的方式手动插入这些部件并安全地拆卸部件，夹紧单元将被垂直设计。为了进一步提高混合部件复杂制造工艺的工艺可靠性和可重复性，预计将采用自动处理系统并通过轨道系统进料。进一步的要求是集成用于加工金属玻璃的系统，作为混合部件，金属玻璃一方面具有高机械性能，另一方面——就未来的研究领域而言——允许新颖的材料组合。为了增加不同基体系统（热固性和热塑性）与钢/有机片材之间的粘合力，在控制系统中提供了预热站，以确保整个工艺流程的平稳和协调。为了绘制和分析注塑工艺参数和连接的外围设备（例如处理系统或预热站），系统必须能够记录测量数据，将其传递给其他系统组件和工艺设置参数。由此创建的数据库还应该可用于过程和结构模拟。
