Daiichi Kogyo is a specialized group that develops and manufactures fastening components, including both bolts and nuts. We conduct "forging," "machining," and "welding" in-house, accumulating production and manufacturing technology. While "forging" is the standard method for screw manufacturing, "machining" is also an important processing technology in screw production, especially when complex shapes or additional processes like drilling are required. Additionally, "welding" is a processing technology used in the manufacturing of fastening components to join two items together. Daiichi Kogyo possesses the manufacturing know-how necessary for "forging," "machining," and "welding" required for screw production. We can also perform "composite processing" that combines these methods. Our accumulated expertise in each processing technology allows us to design processes that leverage the unique characteristics of each method. We have compiled fundamental knowledge on screw manufacturing techniques, specifically "machining" and "welding." We will clearly explain each processing technology, manufacturing processes, and points to note regarding "machining" and "welding" in screw production, accompanied by images for better understanding.
