Can geometries in general be designed better? Can certain components of an assembly be dispensed with altogether? These considerations often lead to significant savings.<\/p>\n<p>Lightweight construction means being efficient and conserving resources. It uses the lightest possible materials. Less material on the product lowers its weight. We work on solutions like these in research and development.<\/p>\n<h2>Up to two-thirds less weight<\/h2>\n<p><a href=\"https:\/\/blog.normagroup.com\/en\/future-of-mobility\/\">A major trend in automotive engineering<\/a> is to replace rubber with thermoplastics. This can significantly reduce weight \u2013 usually on top of improved mechanical strength. If you combine connectors and plastic lines, vehicles can also be mounted faster \u2013 compared to rubber hoses.<\/p>\n<p>Particularly cooling water systems, whether in vehicles with internal combustion engines or <a href=\"https:\/\/blog.normagroup.com\/en\/how-batteries-live-long-in-electric-vehicles\/\">electric drives<\/a>, often consist mainly of rubber. There is immense potential for saving weight: up to two-thirds, depending on the application.<\/p>\n<p>\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/blog.normagroup.com\/wp-content\/uploads\/2018\/01\/NORMA-Group-Produkte-K\u00fchlwasserleitung-und-NORMAQUICK-V3-und-NORMAQUICK-PS3-1024x575.jpg\" alt=\"Cooling lines and plastic quick connectors - like the models V3 and PS3 from NORMA Group on the photo - save up to two-thirds of weight compared to metal and rubber systems. Cooling lines and plastic quick connectors - like the models V3 and PS3 from NORMA Group on the photo - save up to two-thirds of weight compared to metal and rubber systems.\" itemprop=\"image\" height=\"575\" width=\"1024\"  \/><br \/>\n\t\tCooling lines and plastic quick connectors &#8211; like the models V3 and PS3 from NORMA Group on the photo &#8211; save up to two-thirds of weight compared to metal and rubber systems. <\/p>\n<p>But there\u2019s even more. That\u2019s shown by one recent model from a major car maker. By using different steel grades and new manufacturing methods, the manufacturer was able to save around 100 kilograms of weight. 100 kilograms of material is the first win. This protects the environment. It also reduces fuel consumption by 0.3 liters per 100 kilometers and carbon dioxide emissions by 10 grams per kilometer.<\/p>\n<p>That may not seem like much. However, multiplying these values by the number of vehicles in a vehicle generation \u2013 that is, 2.8 million times \u2013 highlights the importance of lightweight construction.<\/p>\n<h2>New materials and processes<\/h2>\n<p>Future materials strive for low density and improved mechanical strength. This can be carbon fibers or basalt fibers reinforced with thermoplastic materials, for example. These fine fibers are embedded in plastic to form a cohesive, rigid construction.<\/p>\n<p>A fiber consists of fine filaments combined into rovings (\u201cbundles\u201d). The K-number indicates the number of filaments in one of these bundles. 1 K corresponds to 1000 filaments. The thickness of carbon filaments varies depending on the fiber type: between 4 and 8 microns. If you compare the tensile strength of a carbon fiber with high strength steel (800 N\/mm\u00b2), carbon shows a five times higher value (4000 N\/mm\u00b2). Such materials will therefore become increasingly important in the future.\u00a0<\/p>\n<p>\t\t\t\t<img decoding=\"async\" src=\"https:\/\/blog.normagroup.com\/wp-content\/uploads\/2018\/01\/Die-Oberfl\u00e4chenbeschaffenheit-von-Carbonfasern-in-einer-Makro-Zoom-Aufnahme.jpg\" alt=\"The surface condition of carbon fibers in a macro close-up.\" itemprop=\"image\" height=\"667\" width=\"1000\"  \/><br \/>\n\t\tThe surface condition of carbon fibers in a macro close-up.<\/p>\n<p>Besides new materials, new production processes are also needed. We use technology scouting to examine new production processes for their potential. One example is thermoplastic foaming. In the process, a microcellular structure is built up inside the wall thickness.<\/p>\n<p>This enables 5 to 15 percent weight savings. In injection molding, the microcellular foam structure adopts the holding pressure required to compensate for shrinkage on the component. This reduces time for the entire cycle by up to 20 percent.<\/p>\n<p>Computer-assisted simulation methods can also help optimize product design. Topological methods in particular, such as soft kill options (SKO) or computer aided optimization (CAO), are well suited for this.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>By replacing rubber in favor of thermoplastics, vehicles could become significantly lighter and more environmentally friendly.
