Syväveto

Syväveto is a Finnish term referring to a drawing process where a sheet of metal is formed into a deep, hollow shape. This is typically achieved by using a punch that presses the metal into a die cavity. Unlike shallow drawing, syväveto involves significant elongation of the material, allowing for the creation of complex three-dimensional forms.

The process is widely used in various industries, including automotive, aerospace, and household appliance manufacturing. It is particularly suited for producing parts that require intricate shapes and high strength, such as car body panels, fuel tanks, and cookware. The depth of the draw is limited by the material's ductility and the tooling design. Multiple drawing steps may be required for very deep or complex geometries.

Syväveto can be performed on various metals, including steel, aluminum, and brass. The success of the process depends on several factors, such as the material properties, lubrication, and the precise geometry of the punch and die. Material thinning is a common phenomenon during syväveto, and careful control is needed to prevent tearing or wrinkling. The resulting parts are often seamless and possess good structural integrity.
