Lightweight construction \u2013 three new approaches to production \u2013 Photos<\/a><\/b><\/p>\nThese platforms are usually designed in such a way that they can withstand the maximum expected load level. With many derivatives, this leads to oversized components and thus to excessive heights of the vehicles. \u201cEspecially when an expensive lightweight material such as carbon is used, oversizing is usually not worthwhile,\u201d said Kropka. Carbon should only be used if the specific load level requires a higher resistance of the material used.<\/p>\n
A tool kit for components with varying load requirements<\/p>\n
With the \u201cHybCar\u201d concept, underbody components with varying load requirements are to be created with a single set of tools. The core of the process is the hybridization of the circuit board (metal \/ thermoplastic CFRP). This combines the forming, joining and consolidation of the polyamide 6-based fiber composite material in one process.<\/p>\n
The local reinforcement with fiber composite materials makes it possible to reduce the sheet steel thickness from 2.5 mm to 0.7 mm; and thus to build the entire vehicle floor less high. In addition, thanks to the flexibility in the thickness of the fiber composite insert, the floor assembly can be designed and scaled as required. In the project, the front footwell gained over 18 millimeters in height.<\/p>\n
\u201cThe weight of the underbody component fell by over ten kilograms compared to the benchmark,\u201d said Kropka, \u201caround 40 percent.\u201d A fully automated production process also reduces the cycle time for production to less than 90 seconds. When asked about a recycling concept, Michael Kropka explained that \u201cthat was not part of the project, but the composite and sheet steel can be separated\u201d.<\/p>\n
\u201cOn-the-fly injection molding\u201d<\/p>\n
Michael Krahl, Managing Director of the Dresden-based company Anybrid, gave his lecture the distinctive title \u201cInjection molding learns to fly\u201d. Krahl described the current status, \u201cInjection molding is often used for material combinations, for example in metal processing, thermoforming or extrusion. The systems are at the center of production. Why can\u2019t we combine these two construction methods directly? \u201d, Krahl led on to the core of his lecture.<\/p>\n
His company has developed \u201cRobin\u201d for this, \u201cRobotized Injection Molding\u201d, a movable injection molding machine. It consists of an injection unit, an injection molding tool and a lightweight C-frame \u2013 in the example, the system was mounted on a robot arm. The clearest advantage: It can be integrated into existing process lines.<\/p>\n
Functional elements can be applied locally to large component structures, for example, or assemblies can be functionalized. \u201cWith our system we want to get into other processes,\u201d said Krahl, describing the goal. Combinations of materials are conceivable, for example wood \/ plastic, metals, steel and aluminum. \u201cThis can make completely new products possible that could not be implemented otherwise.\u201d A specific example that Michael Krahl showed was the application of plastic elements to a pipe structure \u2013 in the process of laser tape winding.<\/p>\n
