[Attention Engineers] Screw manufacturing is not just about forging. There is also cutting and welding. We offer a free [technical document] that provides fundamental knowledge of each technique!

Daiichi Kogyo is a specialized group that develops and manufactures fastening components, including bolts and nuts. 【What a specialized group can do】 While "forging" is the common method for screw manufacturing, "cutting" is also an important processing technique for screw production when complex shapes or additional processes like drilling are required. Daiichi Kogyo possesses the manufacturing know-how necessary for "forging," "cutting," and "welding" in screw production. We can perform "composite processing" that combines these techniques. Forging + Cutting + Welding ⇒ Composite products With the accumulation of each processing technique, we can set up processes that leverage the characteristics of each method. 【Manufacturing Example】Production of parts with strict precision requirements. ● When manufactured using only "forging," the load on the mold increases, raising concerns about mold lifespan and quality deterioration. ↓ ● By switching from "forging" to "cutting" for manufacturing, we can reduce the load on the mold and lower forging costs, achieving quality improvement as well.

You will understand the basic knowledge of "welding processing," which is fundamental to screw manufacturing technology. This will explain the characteristics and precautions of welding processing used in screw manufacturing.

"Welding processing" refers to a method of joining two objects together. It involves melting the joint area of two materials to join them, or adding melted material from an external source to the joint area to connect the two objects. We manufacture cap nuts using "projection welding," a type of pressure welding. We also produce parts by welding stainless steel plates using "TIG welding," a type of fusion welding. We provide clear explanations of the advantages and disadvantages of each welding process, along with examples of manufacturing accompanied by photographs. We would like to introduce our company's screw manufacturing technology, "welding processing." We explain the welding methods and characteristics we employ, complete with photographs. You can gain a basic understanding of "welding processing." Please take a look. We also have materials that showcase examples of improvements in our welding processing operations.

Screw making is not just about forging. I will clearly explain the basics of screw manufacturing technology, "cutting processing," including the processing steps and important points to consider.

"Cutting processing" is a method of machining that shapes materials by cutting them with cutting tools to achieve the desired form. While "forging processing" is commonly used for screw manufacturing, "cutting processing" is also an important machining technique in screw production, especially when complex shapes or additional operations like drilling are required. At Daiichi Kogyo, we manufacture a variety of products, including aluminum nuts, stainless steel nuts, front bosses, and bushes, through "cutting processing." We also possess technical know-how for "forging processing" and "welding processing," allowing us to produce composite machined products that combine these techniques. This document clearly explains the advantages and disadvantages of cutting processing, examples of screw manufacturing processes using cutting processing, and points of caution and countermeasures in cutting processing, all accompanied by photographs.

Combination of "plastic processing" and "cutting processing"!

There are various processing methods in metalworking, including casting (foundry), plastic processing (forging, pressing, rolling), sheet metal processing (pressing, drawing), cutting processing (lathe, milling, drilling), grinding processing (polishing, grinding), and joining processing (welding, brazing). This time, we will introduce the combination of "plastic processing" and "cutting processing," which our company specializes in. In our fastener division, we combine "cold heading" from plastic processing with "dual-end machining" from cutting processing to produce vibration-damping components for four-wheel vehicles (automobiles), providing high-precision and complex products at low prices that are difficult to achieve with cold heading alone. Additionally, through combinations such as "cold heading" + "NC lathe," we also produce torque converter components for four-wheel vehicles (automobiles), which have received positive feedback from our customers.

We have achieved complex shape forging processing with a reheader machine!

Metal processing includes a method called cold heading, which uses molds to achieve plastic deformation. Cold heading has the advantage of significantly less material waste compared to cutting processes, as well as stable precision and production speed, making it suitable for mass production of items such as bolts and nuts. However, for complex shapes like concave forms, cutting processes were necessary. Our company has introduced a re-header machine (split mold forming machine) that allows us to perform cold heading on semi-finished products after the initial heading process, enabling the formation of complex shapes and eliminating the need for cutting processes through net shape processing. By combining header and re-header machines, we have improved processing efficiency for complex shapes, allowing us to propose solutions for mass production. Additionally, the reduction of waste material from cutting processes helps lower costs.
