Basics of Screw Manufacturing Technology [Forging Edition] First Industrial's Screw Manufacturing Technology (Complete Edition)
This document clearly explains the forging process of bolts, nuts, and collars. It provides information on the basics of screw manufacturing technology, specifically "forging."
"Forging processing" refers to a type of plastic processing that shapes metal materials using molds. Unlike cutting processes, it minimizes material waste and is suitable for mass production. At Daiichi Industry, we manufacture both "bolts" and "nuts" through "cold forging processing." This document includes the advantages and disadvantages of forging processing, as well as examples of the forming processes for bolts and nuts/colors. It also illustrates the differences in manufacturing methods for bolts and nuts with accompanying photos. Additionally, we present examples of improvements in mold design using FEM analysis. <Note> We have added "Types of Cold Forging Processing" to the document. It explains how screws are formed using dies and punches, accompanied by illustrations. For more details, please refer to the download. Feel free to contact us with any inquiries.
