The history of the "Ostrowiec Foundry" dates back to the early 19th century.
In the inter-war period, the Foundry was part of "Zakłady Ostrowieckie", after 1945 it was incorporated into Huta Marcelego Nowotki and then Huta Ostrowiec.

Since 1995 the foundry belonged to Ostrowiec Works, which was separated from Huta Ostrowiec. On 1st of July 1997 Zakłady Ostrowieckie spun off "Odlewnie Ostrowieckie" as an independent enterprise - a limited liability company.

From 2003 to 2004, Odlewnia functioned together with Ciepłownia as Energetyka Cieplna and Odlewnie Ostrowieckie spółka z o.o.

In 2005, due to the discontinuation of heat production, the company's name was changed to "Odlewnia Ostrowiec" spółka z o.o.

Odlewnia Ostrowiec produces single units, small batch and medium batch castings made of steel.

The foundry specialises in the production of ladles for the steel, copper, tin and lead industries. In addition, it produces other castings up to 30 tonnes for the metallurgical, cement, energy, mining, engineering, shipbuilding and construction industries.

In addition to domestic customers, the main customers for castings are from Europe and the USA.

Foundry departments

We deal with the production of castings comprehensively: from the development of technology to the shipment of the finished product

  • Technical department

    Odlewnia Ostrowiec Sp. z o.o. is able to design new types of heavy castings for wide range  of different industries. To keep the  highest quality of castings we use software such as: Solidworks, Solidworks Simulation, Magma Soft, Magma Stress, Magma Iron, Solid Edge. The technical department also works on the basis of customer documentation.
  • Moulding department

    Moulding department is equipped with sand mixer with total capacity of 40 tons per hour. Moulding process is based on furan sand masses.
  • Melting department

    Foundry is equipped with electric arc furnace with the capacity of 30 tons and produces castings with weight range 300 kg – 30 tons. In 2024 we started new investment and within a year we should launch a new furnace with a capacity of 40 tons.
