öntéses

Öntéses is a Hungarian term that broadly refers to the process of casting, a manufacturing method in which a liquid material is poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is known as a casting, which is ejected or broken out of the mold to complete the process.

This technique is widely used for creating complex shapes that might be difficult or uneconomical to make by other manufacturing methods. The materials commonly used in öntéses include metals, such as iron, steel, aluminum, and bronze, as well as plastics, ceramics, and even concrete. The choice of material depends on the intended application of the final product.

The process typically involves several stages. First, a mold is created, often from sand, metal, or plaster, which accurately replicates the desired shape. Then, the chosen material is heated until it becomes liquid and is poured into the mold cavity. Once the material has cooled and solidified, it is removed from the mold. Öntéses can be used for producing a wide range of items, from small intricate components to large industrial parts. Its versatility makes it a fundamental technique in many industries, including automotive, aerospace, and construction.
