LANXESS serves customers in the lighting, electrical, and electronics industries through all development phases of plastic components. “We want to develop component solutions with our customers, which are optimally tailored for all stress scenarios and requirements, and which are also convenient and economical. For example, we check the suitability of a material for a certain application as quickly as possible. This enables our customer to ensure purposeful development,” explains Frank Lutter, CAE team leader in the Customer Engineering Services division in HPM.
One highlight of HiAnt is a simulation tool, which enables components to be designed with the right plastics in order to efficiently dissipate heat. It takes the component geometry, installation situation, and heat input into account. It can be used to show how the temperature of an LED heat sink, for example, depends on its geometry and source material. “We can also visualize the flow of air (air convection) around a component. This enables design engineers to align cooling ribs with the convection, for example, to improve heat dissipation,” Frank Lutter explains. These simulations help to save costs and time, as the prototyping workload is reduced and a large part of the development work can be conducted virtually by computer.
Another key service element of HiAnt is the computational design of components, which are subject to strong mechanical stresses due to shock or impact, for example. LANXESS can thus carry out computational simulations of the hammer and ball-drop impact tests commonly used in the lighting industry and adapt the design of a housing to the forces by making modifications to reinforcing ribs.
