Robots are being put in motion in a wide variety of fields of application. One of the factors of reliable performance is therefore making the right choice in materials to be used. With its low dead weight (20 % weight advantage vs. POM or PA6) and practically unlimited mould casting possibilities, this high performance plastic from Lauramid® is predestined for dynamic components in moving applications. Just like the 3D original of a robot arm based on an exploded view, presented at the Hannover Trade Fair. For daily use in a paint shop, the lubricant-free operation of the Lauramid® component is a bonus with its chemical resistance to the paints and solvents that are used, as well as its electric insulation capacity of up to 100,000 V.The chest-high arm displays individual arm parts, connectors and hinges from Lauramid®. The visible metal spacers on this model are for visualisation only, and are not components of the original unit in which the parts presented here are directly connected. In this representation, the hollow wrist design of every Lauramid® component is also visible from the inside. The hollow design was also moulded using casting technology, as were the sophisticated external freeform surfaces. With this type of manufacturing, a later machining of the part is unnecessary. At heavily loaded points on both of the robot's hinges, aluminium inserts were also permanently moulded directly into Lauramid® during the manufacturing process. In this example, these act as a slot for the ball bearing.
