A document summarizing the screw manufacturing technology of Daiichi Industry (forging, cutting, welding) is now available!

第一工業 第一工業 鋲螺事業部(ネジ・ボルト・ナット等締結部品 製造販売. 静岡県浜松市)
Do you know how the screws around you are made? There are various methods for processing screws, including cutting processes that remove metal, plastic processes that shape metal by compressing it, and welding processes that melt and join metals together. Each method has its own advantages and disadvantages, as well as different shapes and materials it excels at processing. Our company possesses the manufacturing know-how necessary for screw production, including "forging," "cutting," and "welding." We also offer "composite processing" that combines these methods. By leveraging the characteristics of each process, we achieve optimal cost and quality in screw manufacturing. As a specialized group in fastening components, our company, which handles "forging," "cutting," and "welding," has published materials summarizing each of these technical details. For more information, please download and view the catalog page below.

[Technical Information] Understand the Basics of Screw Manufacturing Technology [Forging Process]

[Attention Engineers] The Basics of Screw Manufacturing Technology: "Forging Process." We are currently offering free technical materials on "Basic Knowledge of Forging Process," which explains the differences in the manufacturing of bolts and nuts.

Many "screw products" such as bolts and nuts are manufactured using "forging." "Forging" is a processing method that uses molds to shape metal materials by compressing them. It has many advantages, such as good yield, suitability for mass production, and increased strength due to work hardening. Although both are "screw products," bolts and nuts differ in materials, manufacturing processes, and manufacturing equipment. At Daiichi Kogyo, as a specialized group that manufactures both bolts and nuts, we have accumulated production and manufacturing technologies that correspond to each of these differences. We also utilize FEM analysis to conduct forging simulations, which are applied in process design and mold design. The reason we can manufacture both bolts and nuts can be found in the link below: "Production and Manufacturing Technology of the Specialized Group." A specialized group that manufactures both bolts and nuts has compiled "Basic Knowledge of Forging." We provide a clear explanation of the actual processing steps with accompanying photographs. Improvement examples utilizing FEM analysis are also included. Please download and take a look.

[Technical Information] Basics of Screw Manufacturing Technology [Cutting and Welding] Will Be Taught

[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. For more details, please visit the following 【Daiichi Kogyo Co., Ltd. Fastener Division Fastening Components Site】. We are currently offering free technical materials that provide basic knowledge of screw manufacturing techniques, including "cutting and welding." Please download and take a look.

[Please introduce this to the management and general affairs department] Update on the introduction case of expense reimbursement and attendance management system! We want to eliminate paper-based reimbursement and application processes. The checking work that used to take three days can now be completed in one day.

  • NEW
  • OTHER

An article has been published regarding the case study of the introduction of the expense reimbursement system "Rakuraku Seisan" and the attendance management system "KING OF TIME" at Racam Co., Ltd. ~ In the case of Racam ~ Before the introduction of "Rakuraku Seisan," applications were paper-based. One person was responsible for checking the contents for about 100 individuals using a calculator. Since actually using the system, various tasks related to determining who to pay and how much have been reduced, and it has become possible to import the crucial journal entries. Most importantly, the elimination of the need to research transportation costs one by one has been a significant improvement. The successful implementation of the attendance management system was made possible by the generous support provided by iBP. [Case Overview (Partial)] ■ Challenges Before Implementation - Wanted to eliminate paper-based reimbursement and application processes ■ Key Points of Implementation - High recognition of Rakuraku Seisan - With iBP, both expense reimbursement and attendance management can be handled together *For more details, please refer to the related links or feel free to contact us.

Case Study 003: Verbalizing the "somewhat inconvenient" issues faced by HR and General Affairs. A case of organizing challenges and proposals. Client in the home care industry with approximately 700 employees.

  • NEW
  • OTHER

"Somewhat inconvenient" can quickly transform into "cost" and "risk" due to an increase in the number of employees or an expansion of business scope. What we are introducing this time is the process of a home care industry company with around 700 employees verbalizing their frustrations regarding payroll operations and considering the optimal system configuration. When we verbalize "somewhat inconvenient"... 1) The support quality of the payroll system being used is poor, causing significant stress. 2) The number of employees has been on the rise in recent years, raising concerns about running costs due to the pay-per-use system. 3) Macros are being used for data integration with a separate system. 4) We want to make backend processes like payroll payment reports easier. Information from iBP What is important here is to decide how to handle the multiple issues that have arisen, which is the "prioritization of tasks." You can read more without needing to input personal information. Please visit the iBusiness Partners column page! https://ibp-column.sfsite.me/36302
