But even this method has great potential for increased efficiency. Through targeted temperature management and heating of clearly defined mold areas, valuable cycle time can be saved. Note de contenu : - Temperature management by air gaps - A copper layer directs the induced eddy currents - Combination of the two variants - Measurements on the actual construction - Faster heating with less energy - FIGURES : 1. Depending on requirements, external or internal arrangement of the inductor is recommended - 2. CAD model of part of the coated test geometry. Longitudinal section and cross section. The inductor in the inductor channel is not shown - 3. Qualitative comparison between thermal simulations of a solid material strip and a copper-coated air gap strip. The latter is only heated in the central uncoated block - 4. Actual test construction made from tool steel 1.2312 (black, lacquered). The holes allow the temperature curve to be measured En ligne : https://drive.google.com/file/d/1NMgqPQowUuj8lgjgZ5ptMWmhkA5VnwR2/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=30084 [article]
