Discover optical simulation, a key element for the rapid and accurate design of laser-welded plastic components, allowing to accelerate and optimize the development of complex parts.
Laser transmission welding of plastic materials is a rapid assembly process that allows for clean and highly mechanical strength welds — a process that is particularly appreciated in industry.
However, the design of complex 3D welds can be difficult: numerous tests, often long and tedious, are necessary to ensure homogeneous energy density and constant mechanical properties over the entire length of the welded joint.
In order to reduce this effort, a macro was developed and validated within the Zemax OpticStudio optical simulation software to simulate the laser welding process.
This tool makes it possible to optimize, in a very short time, the energy density and the mechanical properties along the welded joint.
Parameters from the simulation can be directly applied to the actual welding process, ensuring optimized, faster, and less expensive design of laser-welded plastic products.
These developments took place as part of an InnoSuisse project, in collaboration with the company Leister.
