The vast majority of fastening products are manufactured by cold forging. At RED HORSE, we have machines for heading, pointing, threading, and much more.
Cold forging is a manufacturing method with roots dating back to the 18th century. In essence, it involves using great force to transform a metal into a desired shape. Screws are made of steel or aluminum from a wire coil. The wire is carefully selected to match the screw's design and application.
In the manufacturing of a screw, different cold-forging processes are involved, such as heading, pointing, and thread rolling. These processes are explained and described below:
The heading machine straightens out and cuts wire into a piece. The piece is then struck twice, where the first strike partially forms the head. The second strike shapes the final head, including a potential recess.
The drill point is formed by striking two tools together around the tip of the wire piece, which deforms the tip into the desired drill point shape.
