Step 3:Heat Treatment
To optimize strength and durability, metal fasteners undergo precise heat treatment.
This controlled process involves heating, quenching, and tempering to transform
the material’s microstructure, significantly improving hardness and tensile
strength while maintaining essential toughness.
Step 4: Surface treatment
Metal fasteners receive protective coatings like zinc plating, powder coating, or electroplating to prevent rust and wear. These treatments extend product life while improving corrosion resistance and appearance for demanding applications.
Step 5:Machining and cutting
Following heat and surface treatments, fasteners undergo precise finishing operations including thread cutting, hole drilling, and end trimming. These final machining processes ensure every fastener meets exact dimensional specifications and functional requirements for reliable performance
Step 6: Quality inspection
Throughout manufacturing, we enforce rigorous quality control protocols. Every production batch undergoes comprehensive testing of critical parameters – dimensional accuracy, mechanical strength, thread precision, and surface integrity – to guarantee full compliance with international standards such as ISO, DIN, and ASTM specifications.
