Ziehprozess

Ziehprozess refers to a metal forming process where a solid metal blank is drawn through a die. This process elongates the metal and reduces its cross-sectional area, shaping it into a desired form, often a wire, rod, or tube. The die has a specific shape that dictates the final product's dimensions.

The process typically involves pulling the metal blank through the die by applying tensile force. Lubrication is crucial to reduce friction between the metal and the die, preventing damage to both and ensuring a smooth surface finish on the product. Various types of lubricants, such as oils, soaps, or waxes, are used depending on the metal being worked and the specific requirements of the process.

Ziehprozess can be performed at room temperature (cold drawing) or at elevated temperatures (hot drawing). Cold drawing generally results in a stronger, harder product with a better surface finish due to work hardening. Hot drawing, on the other hand, allows for greater deformation and is often used for metals that are difficult to form at lower temperatures.

Applications of Ziehprozess are widespread, including the production of wires for electrical conductivity, cables, and springs, as well as seamless tubes for various industrial uses, and rods for fasteners and structural components. The precision and versatility of Ziehprozess make it a fundamental technique in modern manufacturing.
