Ziehform

Ziehform refers to a specific type of mold used in manufacturing processes, particularly in metalworking and plastics processing. It is a tool that shapes a workpiece by pressing it into or through a shaped cavity. The term "Ziehform" is German and translates directly to "drawing mold" or "pulling mold."

These molds are essential for creating complex geometries and achieving precise dimensions. In metal forming, Ziehformen are used in processes like deep drawing, where a flat sheet of metal is pulled into a die to create a hollow shape, such as a car body panel or a cooking pot. The mold typically consists of a die (the stationary part) and a punch (the moving part) that work together to deform the material.

In plastics processing, Ziehformen can be employed in techniques such as vacuum forming or injection molding, where molten plastic is forced into a mold cavity to take its shape. The design of a Ziehform is critical to the success of the manufacturing process, influencing factors like material flow, stress distribution, and the final product's surface finish and dimensional accuracy. The creation of these molds requires precision engineering and often involves sophisticated machining techniques.
