Fastener
The fastener industry manufactures critical components that mechanically join or affix two or more parts. These include bolts, nuts, screws, rivets, washers, and specialty threaded products used in sectors like automotive, aerospace, construction, heavy machinery, and electronics. Fasteners are typically made from carbon steel, stainless steel, alloy steels, or non-ferrous metals and are designed to meet rigorous performance and durability requirements.
Precision, strength, corrosion resistance, and heat treatment consistency are crucial, especially for high-load or safety-critical applications.
How Induction Heating Supports Fastener Manufacturing
Induction heating is a valuable tool in fastener production due to its speed, precision, and ability to integrate with automated lines. It provides controlled heating for forming, hardening, and coating processes, helping ensure consistent performance and throughput.
