IAS

What IAS does

IAS GmbH, doing business as IAS Induction, is a German manufacturer of inductive heating and melting systems for industrial and metallurgical applications, headquartered in Iserlohn and operating as a wholly-owned subsidiary of the SMS group. The company originated as a repair service provider before evolving into a specialist for induction furnace construction and now ranks among international technology leaders in the segment alongside its induction solutions and special machines.

Its product portfolio centers on three pillars: inductive heating systems for aluminum, copper, steel, and specialty alloys (covering pre-heating, intermediate heating, post-heating, and heat treatment); induction melting systems under the MetalLine brand including channel furnaces, crucible furnaces, holding/casting furnaces, vacuum induction crucible furnaces, and R&D furnaces; and in-house developed IGBT-based power converters (Direktumrichter and Schwingkreisumrichter) plus induction coils. The HybroHeat® registered trademark anchors an inline heating offering for aluminum. The company emphasizes energy-efficient operation, modular plant concepts, and a "complete from a single source" delivery model covering planning, construction, commissioning, and aftermarket service.

IAS makes money primarily through one-time capital equipment sales of project-priced induction plants to industrial metals customers, complemented by a professional services layer covering engineering, commissioning, on-site service, spare parts, modernization, retrofit/upgrade, and a 24/7 emergency hotline. Its go-to-market is enterprise field sales with direct technical consultation, custom plant planning, and comprehensive after-sales support. Approximately 70% of revenue is generated abroad, with primary customer segments being press and forging plants and foundries processing aluminum, copper, brass, zinc, tin, cast iron, and steel.
