syvävetämisessä

Syvävetämisessä is a Finnish term that translates to "deep drawing" in English and refers to a manufacturing process. It is a metal forming technique where a sheet metal blank is pushed into a die cavity by a punch. This process allows for the creation of complex three-dimensional shapes from flat sheets of metal.

The process begins with a flat metal blank, typically circular or rectangular, placed over a die. A punch then descends, forcing the metal into the die cavity. The shape of the die and punch determine the final form of the drawn part. Lubricants are essential to reduce friction between the metal and the tooling, preventing tearing and ensuring a smooth drawing process.

Syvävetämisessä is widely used in various industries, including automotive, aerospace, and consumer goods. It is employed to produce parts such as car body panels, kitchen sinks, ammunition casings, and cookware. The advantages of this method include its ability to produce parts with excellent structural integrity, high precision, and relatively low cost for mass production. It is particularly effective for creating seamless, hollow components. The depth and complexity of the drawn part are limited by the material's properties, such as its ductility and tensile strength, as well as the tooling design and the lubricant used.
