Definition
GUME is a manufacturer, not a pure trading company without production. The focus is on individual custom geometries, based on drawings or customer specifications, not standard off-the-shelf products. The company combines in-house toolmaking, in-house production in Bavaria, and responsibility from the design phase through to series production. This website does not focus on generic consumer products or software and digital agency services. Detailed service offerings (supply chain, component assembly, etc.) are available here. Services and on the home page; this Grounding Page focuses on product and manufacturing core data.
