Öntöde

Öntöde is a Hungarian term referring to a foundry, a place where metal casting is performed. In a foundry, molten metal is poured into a mold, which contains a hollow cavity of the desired shape. Once the metal cools and solidifies, it is removed from the mold as a cast object. Öntöde operations are fundamental to manufacturing a wide range of metal products, from intricate artistic sculptures to large industrial components.

The process typically begins with the creation of a mold. Molds can be made from various materials, including sand, metal, plaster, or ceramics, depending on the type of casting and the metal being used. The molten metal is heated in a furnace until it reaches its melting point, then carefully poured or injected into the prepared mold. After a sufficient cooling period, the casting is extracted, and any excess material, such as sprues or gates, is removed. Finishing processes like trimming, grinding, and sandblasting are often employed to achieve the final desired shape and surface quality.

Foundries employ different casting techniques, such as sand casting, die casting, investment casting, and centrifugal casting, each suited for specific applications and material properties. The work performed in an öntöde is crucial for industries including automotive, aerospace, construction, and art, providing essential metal parts and decorative items. Safety protocols are paramount in foundries due to the high temperatures and heavy materials involved.
