Overview
Teksid is an Italian industrial company specializing in castings and cast-metal components for the automotive industry. Based in Carmagnola, Italy, the company traces its origins to Ferriere Piemontesi and adopted the Teksid name in January 1978. Its manufacturing scope includes iron, aluminum, and magnesium castings, with products covering engine blocks, cylinder heads, other engine components, transmission parts, gearboxes, and suspension components. The company developed within the Fiat industrial sphere and is now wholly owned by Stellantis. Its ownership history reflects changes in the automotive groups that preceded Stellantis: Fiat owned Teksid from 1978 until the formation of Fiat Chrysler Automobiles, which controlled it from 2014 to 2020. Following the creation of Stellantis, Teksid became part of the new group's industrial portfolio. Teksid's output supports various Stellantis vehicle businesses while also being sold to third-party automotive companies. A significant strategic change occurred in 1998, when Renault combined its foundry operations with Teksid. The transaction created a shared ownership structure in which Fiat held 66.5% and Renault held 33.5%. Fiat subsequently increased its stake to 84.8% by 2013, while Renault retained 15.2% before Teksid later became fully controlled by Stellantis. Teksid operates an international manufacturing network. The referenced company profile describes five plants, comprising three in Europe, one in South America, and one in China, and reports a workforce of approximately 3,500 people. In China, Teksid has a 50% interest in Hua Dong Teksid Automotive Foundry Co. Ltd. The company's role is that of a tier-one or strategically integrated casting supplier: it converts ferrous and non-ferrous alloys into complex, production-scale components designed for vehicle powertrains, transmissions, and chassis systems. Teksid's positioning is based on metallurgical expertise, high-volume foundry manufacturing, and integration with major automotive manufacturers. Its business is closely connected to vehicle-production cycles and to the continuing requirements of internal-combustion, hybrid, and other automotive platforms. The available reference material does not establish a separate consumer-facing product brand, public listing, current executive roster, or standalone corporate website. Teksid is therefore best understood as a business-to-business manufacturing brand operating within the Stellantis group.
History
Teksid originated as Ferriere Piemontesi, an Italian foundry business that became associated with Fiat's industrial operations. The company was renamed Teksid in January 1978. Its core activity has been the production of cast-metal components for vehicle manufacturers, initially centered on iron and later extending to aluminum and magnesium applications. The company's ownership and industrial structure changed significantly in 1998, when Renault merged its foundry business with Teksid. The combination established a joint ownership arrangement between Fiat and Renault, with Fiat holding 66.5% and Renault 33.5%. This arrangement linked Teksid to the production requirements of two major European automotive groups and broadened its role as a supplier of castings and related components. Fiat increased its stake over time. By 2013, Fiat held 84.8% of Teksid and Renault held 15.2%. Teksid subsequently remained within the Fiat corporate succession: Fiat S.p.A. controlled the company through 2014, after which Fiat Chrysler Automobiles became the relevant parent group. FCA's period of ownership lasted from 2014 until the creation of Stellantis in 2021 through the combination of FCA and Groupe PSA. Teksid is described in the reference material as wholly owned by Stellantis. Teksid's manufacturing activities cover iron, aluminum, and magnesium castings used in vehicle systems. Its product range includes engine blocks, cylinder heads, engine components, transmission parts, gearboxes, and suspension components. These products are supplied to Stellantis-related automotive businesses and to third-party companies, making Teksid an industrial supplier rather than a consumer-facing vehicle brand. The company has an international footprint comprising five plants in the cited profile: three in Europe, one in South America, and one in China. The same source reports approximately 3,500 employees. Teksid also has a 50% ownership position in Hua Dong Teksid Automotive Foundry Co. Ltd. in China. The available material does not provide a complete plant-by-plant history, detailed production capacities, current management roster, financial statements, or a confirmed standalone corporate website. Those areas require further verification before being added to the encyclopedia record.
