fixed positions and allow them to pass through the firing furnace together.\nBecause multiple components are processed simultaneously, lot management at the sagger level is essential.\nSince saggers are reused repeatedly, fixture management challenges also arise, including:<br>\n\u30fbDamage or cracking of saggers over time<br>\n\u30fbDifficulty tracking the number of usage cycles<br>\nHowever,<br>\n\nestablishing traceability at the firing stage was difficult because:<br>\n\u30fbVery few labels can withstand firing processes exceeding 1,000 \u00b0C<br>\n\u30fbThe container shape makes mounting methods such as tag placement,<br>\nwelding, or screw fixing unsuitable\n\n<\/div>\n<\/div>\n<div class=\"row\">\n<div class=\"th\">\u3010Solution \/ Benefits\u3011<\/div>\n<div class=\"td\">CERALABEL GL provides heat resistance selectable from 400 \u00b0C to 1,200 \u00b0C, depending on the firing conditions.\nBecause the label is provided in an adhesive format, it can be applied directly to the sagger on-site.\nThe label can either be:<br>\n<br>\nThe label can either be:<br>\n\u30fbfired together with the product, or<br>\n\u30fbpre-fired before use<br>\nallowing the label to fuse to the ceramic surface and remain permanently attached, enabling repeated use across multiple firing cycles.\nIn this case, labels were printed using the customer\u2019s existing on-site printer, allowing seamless integration with upper-level systems. <br><br>\n\nKey Benefits <br>\n\u30fbLot traceability established at the sagger level from the firing stage<br>\n\u30fbIdentification numbers generated by MES and other upper-level systems can be printed directly using on-site printers<br>\n\u30fbAccurate tracking of fixture (sagger) usage cycles, enabling optimal replacement timing<br>\n\u30fbSupporting smart manufacturing with minimal changes to existing operations<br>\n\n<\/div>\n<\/div>\n<\/div><\/section>","protected":false},"excerpt":{"rendered":"\u3010\u30b1\u30fc\u30b9\u540d\u3011
