About wiemo & WICOBO
wiemo GmbH & WICOBO GmbH in Solingen specializes in the manufacturing of sand cores for the foundry industry. wiemo GmbH (founded 1987) produces cores using the Croning process, while its sister company WICOBO GmbH, founded in 2002, manufactures cores using the Cold-Box process. In addition to individual cores, the company supplies castable, assembly-ready core packages, including processing steps such as drilling, finishing, drying, and assembly. Strahl (blast) operations (ice, glass, and plastic blasting) are also offered as a subcontracted blasting service. Packaging and pan-European logistics round out the range of services. Production ranges from prototype to series in various core sizes. Since 2005, the company has been certified according to DIN EN ISO 9001. wiemo & WICOBO supplies foundries throughout Europe from its own production facility on Martinstraße.
