Cold Forming
Cold forming, also known as cold heading, is a manufacturing process used in the fastener industry to shape metal into various fasteners such as screws, bolts, and rivets. This process involves deforming metal at room temperature using high-pressure machinery. Here’s a brief overview:
- Process: Cold forming typically starts with a wire or rod of metal, which is cut to a specific length. The metal is then inserted into a series of dies and struck by hammers or punches to shape it into the desired form. This can include forming the head, threading, and other features of the fastener.
- Advantages:
- Strength: The cold forming process increases the metal’s strength and hardness due to work hardening.
- Efficiency: It allows for high-speed production with minimal material waste.
- Precision: The process ensures consistent dimensions and high-quality surface finishes.
- Materials: Various metals can be cold formed, including steel, stainless steel, aluminum, brass, and copper.
- Applications: Cold-formed fasteners are widely used in automotive, aerospace, construction, and electronics industries due to their enhanced mechanical properties and reliability.
Overall, cold forming is a cost-effective and efficient method for producing high-strength, precision fasteners in large quantities.
