Automotive Industry
The following section outlines key fastener technologies and their applications in passenger vehicles.
Fastener Manufacturing Processes
- Cold heading: Used to produce bolts, screws, and other cold-formed fasteners from wire or rod stock, delivering high dimensional accuracy and production efficiency.
- Hot forging: Applied in the manufacturing of larger and high-strength fasteners, such as wheel studs and structural bolts, where superior mechanical performance is required.
- Threading: Threads are created through rolling, cutting, or forming processes to achieve precise fits and reliable fastening performance.
- Heat treatment: Processes such as quenching and tempering are used to enhance fastener strength, hardness, and long-term durability.
- Surface treatments: Including electroplating, anodizing, and protective coatings, are applied to improve corrosion resistance, extend service life, and reduce maintenance requirements.
