Production process
Process Steps
Process consistence
The production process of Replacement Blade Bolts includes multiple steps such as raw material selection, cold heading, heat treatment and surface treatment.
First steps
First, high-quality raw materials are selected, and after wire drawing, they enter the cold heading process. Cold heading is a process that uses the plastic deformation of metal to forge the metal blank into the desired shape through a die.
Second Steps
Next, the bolt will be heat treated to improve its strength and toughness. Finally, surface treatment such as zinc plating, nickel plating, etc. is performed to enhance the corrosion resistance and aesthetics of the bolt.
