What Lancer does

Fonderie Schlumberger is a French cast iron foundry integrated within the NSC Groupe industrial conglomerate, producing lamellar graphite (GJL) and ductile/spheroidal graphite (GJS) iron parts in small and medium production runs. The facility, located in Guebwiller, Alsace, produces parts ranging from 0.5 kg to 600 kg using two Heinrich Wagner Sinto high-pressure moulding lines, four electric induction furnaces (three 4-tonne and one 5-tonne) totaling roughly 17 tonnes of melt capacity, a 60-tonne/hour automated sand plant, and MAGMA-based filling and solidification simulation. In-house heat treatment supports parts up to 1400 mm x 1200 mm, while painting, surface treatment (cataphoresis, zinc lamellar coating, dichromate plating, galvanising), and precision machining are coordinated through qualified local subcontractors under foundry responsibility to deliver ready-to-install components.

The foundry serves four primary end-markets: machine construction (wind turbines, hydroelectric micro-generating plants, industrial washing machines, robots, refrigeration and air conditioning equipment), textiles (wool preparation, weaving, cotton preparation, non-woven machinery — including sister company N. Schlumberger), transport (tramways, trucks, agricultural machinery, all-terrain vehicles for civil and military sectors, plus end-of-series spares), and miscellaneous industrial uses (public works, civil engineering, hydraulics, mining, electrical construction, nuclear and renewable energies). Its tri-border location at the intersection of France, Switzerland, and Germany supports cross-border commercial reach.

Revenue is generated through B2B industrial sales of cast iron parts (hardware sales) bundled with finishing services, priced via quote-based custom manufacturing contracts. The business carries ISO 9001-2015 (renewed September 11, 2018) and Marine & Offshore (Bureau Veritas, March 13, 2019) certifications. Fonderie Schlumberger is privately held as a subsidiary of NSC Groupe; specific revenue figures are not publicly disclosed.

Functional benefit

Products and services

• Lamellar Graphite Iron (GJL) Castings Custom cast iron parts produced in grey/lamellar graphite iron (GJL) grades for industrial OEMs, with mechanical and thermal properties suited to engine blocks, housings, valve bodies, and similar heavy industrial components.
• Ductile / Spheroidal Graphite Iron (GJS) Castings Custom cast iron parts produced in ductile/spheroidal graphite iron (GJS) grades for industrial applications requiring higher ductility, tensile strength, and impact resistance than grey iron.
• Heat Treatment Services Industrial heat treatment of cast iron components performed in-house to achieve specified mechanical properties, dimensional stability, and metallurgical characteristics.
• Painting Services In-house industrial painting of cast iron components for corrosion protection, surface finish, and customer-specification compliance.
• Surface Treatment Services Surface treatment of cast iron components performed in-house to deliver required surface characteristics and protective properties.
• Machining Services In-house machining of cast iron parts to deliver finished components to customer dimensional and tolerance specifications.
