In order to produce foam structures with defined properties, the influence of the mold opening speed on the cell density and the influence of a delay time before opening the mould on the surface layer thickness are investigated. Based on the relationship between the properties of the joining partners and the resulting welding result, an optimised process control for the LDS of injection moulded parts produced accordingly is to be developed. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Furthermore, it is to be investigated whether the required surface layer thickness for the production of welds with high weld strength can be reduced by varying the carbon black content in the absorbent joining partner in order to save material and weight. To ensure the broad applicability of the results, further tests are to be carried out to check whether the recommendations derived can also be applied to the welding of foamed compact moulded parts.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary>Project details and thanks<\/summary>\n<p class=\"wp-block-paragraph\">We would like to thank the BMWK for funding within the framework of Euronorm (funding code 49VF210057) and the project partners for their cooperation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Project partners and funding:<\/strong><\/p>\n\n\n<section id=\"logo-bar-block_821530c54b0303f90415300ffa5bdf78\" class=\"block-logo-bar py-2xl  clear-both\">\n    <div class=\"theGridWrapper overflow-hidden  \">\n        <div class=\"grid grid-cols-[repeat(auto-fill,minmax(140px,1fr))] gap-base\">\n                            <figure class=\" relative h-full  \"><img decoding=\"async\" fetchpriority=\"low\"  class=\" object-contain w-full h-full mb-base  \"  src=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/10\/BMWE-Logo.png\" srcset=\"https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/10\/BMWE-Logo.png 500w, https:\/\/ikv-aachen.de\/wp-content\/uploads\/2024\/10\/BMWE-Logo-335x335.png 335w\" sizes=\"auto, (max-width: 748px) 100vw, 748px\" width=\"500\" height=\"500\" alt=\"BMWE-Logo\" loading=\"lazy\" \/><\/figure>                                <\/div>\n    <\/div>\n<\/section>\n<\/details>\n\n\n\n<h2 class=\"wp-block-heading\">Keywords<\/h2>\n","protected":false},"excerpt":{"rendered":"<p>Laser transmission welding (LDS) joins thermoplastic components with maximum precision.
