valukäsittelyn

Valukäsittelyn is a Finnish term that translates to "casting process" or "foundry work" in English. It refers to the industrial process of shaping molten metal into a desired form by pouring it into a mold. This technique is one of the oldest manufacturing methods, with evidence of its use dating back to ancient civilizations.

The fundamental principle of valukäsittely involves heating a metal alloy until it melts, then introducing this liquid metal into a cavity within a mold. The mold is designed to replicate the final shape of the object. Once the molten metal cools and solidifies within the mold, it takes on the mold's shape. The solidified casting is then removed from the mold.

Valukäsittely encompasses a wide range of techniques and materials. Common metals used include iron, steel, aluminum, copper, and various alloys. Molds can be made from different materials, such as sand, metal, ceramic, or gypsum, depending on the desired casting complexity, surface finish, and production volume. Different types of casting processes exist, including sand casting, die casting, investment casting, and centrifugal casting, each suited for specific applications and material properties.

The applications of valukäsittely are extensive, with cast components found in numerous industries. These include automotive (engine blocks, cylinder heads), aerospace (turbine blades), construction (structural elements, pipes), machinery (gears, housings), and art (sculptures). The ability to create complex shapes, internal cavities, and intricate designs makes valukäsittely a versatile and essential manufacturing method.
