The SEVA foundry and its know-how

Each year the SEVA foundry produces between 250 and 300 tons of parts in heat-resistant and stainless steels, nickel and cobalt-based alloys.

It makes use of its know-how in moulding, casting and metallurgy to manufacture parts or products with a high added value. Besides, the industrial facilities of the foundry are significant and enable us to work out outstanding alloys and to cast high-quality parts.

It uses a sand moulding installation (no-bake, gas and self-hardening moulding process).

The sand moulding facilities are suited to produce single parts or small series with a weight ranging from a few pounds to 750 kg.

As far as the melting is concerned, 4 medium-frequency induction furnaces are at its disposal.

These furnaces are equipped with the Gravital process which enables the working-out of the alloys under the protection of a liquid neutral gas such as argon. This protection ensures a very good cleanliness and a minimal content of dissolved gas in the cast alloys.

It implements conventional gravity casting, if necessary, under inert gas.

The process requires conventional chemical bounded sand moulds.

The foundry has got 3 electric furnaces for heat treatment.

These furnaces carry out heat treatment till 1,200°C with the possibility of making it under neutral atmosphere.

The furnaces are equipped with a quick air-cooling system.
