Flex breaks ground on €90 million facility in Hungary. Flex has laid the foundation stone for a new warehouse in zalaegerszeg, Hungary, marking a further milestone in its EUR 90 million investment project in the country. The development includes both a manufacturing plant and a warehouse, and will focus on the production of components for electric and hybrid vehicles. The project is expected to create around 210 new jobs, including approximately 20 positions in research and development. The new facility will supply components to OEMs such as BMW, Ford and Volkswagen, as well as Tier 1 suppliers. Flex operates in 30 countries with more than 100 sites, providing design and manufacturing services across multiple industries, including automotive, industrial, and consumer sectors. According to the Hungarian Investment Promotion Agency, Flex primarily cooperates with domestic suppliers in Hungary, contributing to the competitiveness of the local supply chain and the broader regional economy.

Flex announced new NVIDIA Omniverse DSX Blueprint reference designs on 16 March 2026, offering prefabricated, modular power and liquid-cooling systems for AI data centres. The systems feature an 800 VDC Power Rack and support phased migration from traditional AC setups, positioning Flex as a systems-level partner for hyperscale AI infrastructure rather than a traditional contract manufacturer. The announcement follows Flex's expanded collaboration with AMD to build Instinct AI platforms in Austin. Together, these moves underscore Flex's strategy to become a full-stack AI hardware and infrastructure partner, though customer concentration and potential in-housing of power and cooling capabilities remain key risks. Optimistic analysts project Flex reaching $29.7 billion revenue and $1.4 billion earnings by 2028. The company's shares rose 5.1% following the announcement.
It's just business: manufacturing moves from HP, Flex, AIM MRO and more. A recent look at recent manufacturing business deals, including plans to make the world's largest tofu factory. March 17, 2026 The business of manufacturing never stops. Industrial companies merge, invest and strategically expand to keep competitive, even under adverse business conditions. Read on for more details on five such expansions and acquisitions made by industrial and manufacturing companies. Partnership: HP and Volkmann announced March 3 that the companies would collaborate on a contained metal powder handling solution for metal jet printers. Under the terms of the deal, HP's Metal Jet S100 3D printers will be compatible with specially-designed proprietary Volkmann contained metal powder management systems. In a statement, Alexandre Tartas, a global head of sales at HP Additive Manufacturing Solutions, said the containment solution would improve device efficiency and safety. Expansion: Nasoya announced March 11 it would spend $55 million to expand an existing tofu manufacturing plant in Ayer, Massachusetts. The expansion will add 65,000 square feet of new space and increasing the plant workforce by 20%, for a total size of 200,000 square feet and daily capacity of 400,000 pounds of tofu. The company says that, after the expansion, the tofu factory will be the largest in the world. Partnership: Flex announced March 2 it would expand its manufacturing collaboration with AMD to produce the semiconductor manufacturer's AMD Instinct graphics processing unit platform, which are experiencing a surge in demand alongside the use of GPUs in data centers for AI services. According to a release from Flex, the contract manufacturer has already started manufacturing the AMD Instinct in its Austin, Texas headquarters with plans to increase production. Expansion: Yazoo Mills announced March 12 that it had finished construction of its third paper tubes and cores factory in Hanover, Pennsylvania. According to a company statement, the $14 million plant construction included relocating eight winding lines and 14 recutting machines to the new site.
