Worker cold forms steel blank into screw section for efficient manufacturing of complex shapes.

The worker is forming a screw section by pressing a flat steel blank with a hole in the middle in a hydraulic press. This process, known as cold forming, reshapes the material into the desired screw shape. The resulting component, when welded to a central core, will create a complete screw or auger assembly. Cold forming is commonly used in manufacturing to efficiently produce complex shapes without the need for extensive machining or material waste.
