🇩🇪 Germany
Germany's specialist distributor of shrink, cabling and connection technology — serving industrial, aerospace and automotive markets from Neuhausen since 1978.
Founded in 1978 as a pure shrink tube dealer, Sommer GmbH has grown over four decades into a leading German distributor of shrink, cabling and connection technology. Based in Neuhausen near Stuttgart, Sommer first partnered with Rayfast in 1998 to build a strong European interconnect presence.
Sommer is ISG's European distribution hub, providing German-language technical support and locally held stock across the full range of heat shrink tubing, wire and cable, adhesives, moulded parts and connector accessories. Certified to ISO 9001:2015, the business combines the depth of a specialist distributor with the product breadth and supplier relationships of the wider group.
Sommer serves industrial, aerospace, automotive and defence customers across Germany and continental Europe, providing sound technical advice alongside rapid supply — the same service model that has been the cornerstone of ISG since 1987.
