Last year, an RV manufacturer scrapped 40 custom aluminum panels because the thickness tolerance drifted 0.2mm across the batch. The sheets looked fine at receiving inspection. But during final assembly, those dimensional gaps caused water intrusion failures on three prototype units. That one order cost $28,000 in scrapped material and pushed their production launch back…
A truck body manufacturer in Texas committed to 1,200 square meters of custom 8mm aluminum honeycomb panels from a new supplier in 2025. First container passed incoming inspection with zero rejections. Second container arrived with face sheet thickness swings of 0.3mm between panels — three times the ±0.1mm tolerance their assembly fixtures required. The production…
Last year, an RV manufacturer in Stuttgart swapped their PP honeycomb walls for acp foam core panels across an entire camper line. The reason wasn’t cost — honeycomb ran 12% cheaper per square meter on paper. The real trigger was 340 warranty claims over 18 months, all traced to rivet loosening from road vibration. The…
A shipment of skins that varies in thickness by over a millimeter can snap the fasteners on automated routing tools and shut an assembly line for days. When you spec an aluminum sandwich panel for specialized vehicle builds, hitting that ±0.5mm tolerance is the difference between a smooth production run and a very expensive hard…
