We specialize in technical and commercial consulting for the procurement of cast components. Our team combines many years of foundry engineering experience with practical expertise in international and strategic casting procurement.
We support industrial companies in the technical optimization of cast components, the selection and evaluation of suitable foundries, and the development of sustainable procurement strategies. We consider technical, quality and commercial aspects together – from the design of the cast component to the development of a long-term supplier strategy.
Gusseinkauf.de was founded by Dr.-Ing. Sergey Ershov. He has many years of experience in the strategic procurement of cast components and has held responsible procurement positions in international industrial corporations.
Dr.-Ing. Sergey Ershov studied foundry engineering at TU Bergakademie Freiberg, where he subsequently earned his doctorate in this field. He also completed a business administration program and obtained an MBA from the University of Oxford.
His combination of foundry engineering expertise and international procurement experience forms the basis of our consulting approach: understanding technical relationships, identifying economic potential, and developing practical solutions for casting procurement.
As the author of the specialist book “Stahl- und Eisenguss für den technischen Einkauf” (“Steel and Iron Castings for Technical Procurement”), published by Vulkan-Verlag in 2016, Sergey Ershov also shares his expertise with buyers, design engineers and other professionals involved in the procurement and development of cast components.
