What Baumgarte Iron Foundry does

Eisengiesserei Baumgarte GmbH is a Bielefeld-based iron foundry founded in 1932 by August Baumgarte, operating today as a private GmbH whose share capital was transferred in 2011 to the charitable Baumgarte-Stiftung. The company produces iron-carbon castings in three material grades — grey cast iron with lamellar graphite (EN-GJL), compacted graphite iron (CGI/EN-GJV), and ductile iron with nodular graphite (EN-GJS/GGG) — across piece weights from 0.5 kg to 800 kg. Production capacity stands at 30,000 metric tonnes per annum on 16,000 sqm of manufacturing space, distributed across three moulding lines (DISAMATIC 230 A, Horizontal Moulding Line I, Horizontal Moulding Line II), four Twin-Power medium-frequency melting furnaces delivering 18 t/h throughput, a Cold Box core-making facility with 15 core-shooting machines, mechanical machining, surface coating, and cast finishing incorporating VIBRA-DRUM cooling technology installed in 2018.

Baumgarte runs a vertically integrated foundry-to-finished-part model. Capabilities extend from in-house CAD-based model construction (Euklid, OpenMind) and prototyping through moulding, melting, core-making, casting, blasting, CNC machining, surface coating, and Kanban/reorder-point logistics, enabling delivery of ready-to-install components. The company is certified to ISO 9001:2015, ISO 50001:2018, AD 2000-HP0 (TÜV NORD) for pressure-vessel materials, Bureau Veritas Mode II for maritime applications, and holds Deutsche Bahn HPQ approval for railway components.

The business operates as a direct B2B enterprise supplier to industrial OEMs across pump manufacturing, general machine building, plant engineering, railway technology, vehicle manufacturing, marine engines, and niche applications such as piano construction. Pricing is by quotation based on part weight, complexity, and material grade, with EXW Incoterms 2020 delivery, 30-day payment terms, and ETZ/MTZ energy-and-material surcharges applied when relevant. Sales are handled by a named field team (Jens Gründling, Kevin Gremme, Frank Grimm) plus a dedicated South Germany office in Herbertingen (Roland Ulmer), with no distributor or e-commerce channels.

Core offering

Baumgarte Iron Foundry is a manufacturer of iron-carbon castings, producing cast iron with lamellar graphite (EN-GJL), compacted graphite iron (CGI/EN-GJV), and cast iron with nodular graphite (EN-GJS/GGG) in small and medium series for industrial OEM customers. The foundry runs integrated operations covering moulding, casting, core production, surface coating, cast finishing, mechanical machining, and model construction, supported by in-house 3D CAD tooling and warehouse/dispatch services.

Product overview

Eisengiesserei Baumgarte GmbH is a German iron foundry offering a comprehensive portfolio of cast iron products and manufacturing services. The core products include three grades of cast iron differentiated by graphite structure: Cast Iron with Lamellar Graphite (EN-GJL/grey cast iron), Compacted Graphite Iron (CGI/vermicular), and Cast Iron with Nodular Graphite (EN-GJS/ductile iron). These materials serve diverse industrial applications including pump housings, washing machine parts, railway components, gearbox construction, textile machinery, compressors, and agricultural equipment. The company provides integrated manufacturing services spanning the entire production chain: moulding and casting operations using three production lines (DISAMATIC and two horizontal moulding lines), melting with Twin-Power medium frequency furnaces, core production via Cold Box technology, mechanical machining with CNC centers, surface coating, cast finishing, model construction with CAD/CAM capabilities, and warehouse/dispatch logistics. The offering functions as a vertically integrated foundry service where materials science expertise, production facilities, and post-processing capabilities combine to deliver ready-to-install cast components to customers.
