Öntetteknél

Öntetteknél refers to the techniques and processes involved in the casting of metals. This ancient manufacturing method involves melting metal and pouring it into a mold, where it cools and solidifies into the desired shape. The mold itself can be made from a variety of materials, including sand, plaster, ceramic, or metal, and can be designed for single-use or multiple uses depending on the casting process.

There are numerous öntetteknél employed in industry, each suited for different applications, material properties, and production volumes. Common methods include sand casting, which is versatile and cost-effective for large or complex parts, and investment casting, known for its high precision and ability to produce intricate shapes with excellent surface finish. Die casting, utilizing metal molds under high pressure, is ideal for mass production of smaller, non-ferrous metal parts requiring tight tolerances. Lost-foam casting is another technique that uses a polystyrene foam pattern which vaporizes upon contact with molten metal.

The selection of an appropriate öntetteknél depends on factors such as the type of metal being cast, the required dimensional accuracy, the complexity of the part, the desired surface finish, and the production quantity. Considerations also include the cost of tooling, the achievable mechanical properties of the final casting, and environmental regulations. Öntetteknél is a fundamental process in many industries, including automotive, aerospace, machinery, and art, enabling the creation of a vast array of metal components.
