You will understand the basics of screws. You will also learn about performance evaluation and manufacturing methods. This is a new website dedicated to fastening components!

We are engaged in product development and performance evaluation to shape our customers' requests. We provide testing evaluation equipment and examples of evaluations. We will teach you the basics of performance evaluation.

Screws are small components, but they play a significant role as functional parts in "fastening." Performance evaluation is essential to shape our customers' requests. For example, we have a series of screws designed for special octagonal shapes in resin. The starting point was a customer's request for a nut that wouldn't rotate when embedded in resin. Using FEM analysis, we selected the optimal shape from 40 different designs. Collaborating with the production technology and manufacturing departments, we developed an insert nut that can withstand high torque fastening. To turn requests into reality, it is necessary to have evaluation capabilities to ensure proposed performance. During the development stage, we need to consider performance requirements and mass production feasibility, and after development, we must confirm the design performance and mass production quality, among various evaluations. Our company is equipped with various testing and evaluation facilities, including those developed in collaboration with academia. You can understand the basics of screw performance evaluation, including what kind of equipment is used and what evaluations are conducted. We also provide actual evaluation examples. Please take a look at our development and evaluation tests to shape our customers' requests. More details can be downloaded, and feel free to contact us with any inquiries.

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.

We are offering the textbook "Learning the Basics of Screws" for free, which helps you understand the fundamentals of screws. It includes topics such as "How Tightening Works" and "Loosening and Countermeasures," and is available as part of a series.

Screws are the fundamental mechanical elements that "connect things." They are utilized in various fields, including automobiles, buildings, computers, robots, as well as in asteroid exploration and medical applications. It is said that screws are so common that they can be found "within a radius of 1 meter." Do you know what types of screws exist? You can easily find out by looking at Screw Textbook Vol. 1 [Basic Terms and Types]. Do you know why screws tighten? Screw Textbook Vol. 2 [The Mechanism of Screw Tightening] explains it clearly with illustrations. Do you know why screws loosen? Screw Textbook Vol. 3 [Loosening and Countermeasures] provides a detailed explanation of the mechanisms behind screw loosening and preventive measures. Are you familiar with screw fastening design? Screw Textbook Vol. 4 [Screw Design Part 1] offers an easy-to-understand explanation of the fundamental knowledge necessary for screw fastening design. If you want to learn about screws from the basics, please refer to the PDF materials. Feel free to contact us with any inquiries.

Cannot secure the resin. The resin cracks. "Screws for insert molding" support the fastening of the resin. Free distribution of "Basic Knowledge of Insert Nuts" is ongoing!

Are you having trouble with fastening resin products? You want to tighten them strongly, but the resin cracks. Conventional fastening designs can't be used. You can bond with resin clips or adhesives, but it's a problem if they can't be removed... We have a solution for such "troubles": "screws for insert molding." "What are screws for insert molding?" We offer a technical document that answers that question for free. An insert nut is one type of screw for insert molding. By embedding it in the resin and reinforcing the fastening part, it enables fastening of resin using "bolt + nut." We clearly explain why insert nuts are necessary, how to use them, and the types of resins used, covering the "basics of insert nuts." Our company manufactures the "Octa Lobular Series," screws specifically for fastening resin products. With a special octagonal head shape, it ensures 1.8 times the torque resistance and pull-out strength compared to knurled products, protecting the resin and achieving high-torque fastening. We solve the "troubles" of fastening resin. Please check the detailed documentation of the series available for download. We also have a wide variety of colors for resin. Feel free to contact us with any inquiries.

We have launched a new “Audience Control Feature” for TwooCa Mall, enabling merchants to limit product visibility and sales to specific companies, organizations, and communities. With this feature, merchants can now: ✔ Offer employee-exclusive discounts and company sales ✔ Create fan club or community-only merchandise sales ✔ Customize product visibility for specific user groups In addition, by integrating with TwooCa’s payment functions and digital-money-convertible point system, the platform provides a seamless purchasing experience for users. This feature is designed to support value creation in closed communities such as: ・Employee welfare programs ・Fan clubs ・Membership communities ・Sports teams We will continue expanding TwooCa Mall as a platform optimized for employee engagement, member experiences, and community-based commerce. ▼ Press Release https://prtimes.jp/main/html/rd/p/000000108.000076589.html #TwooCa #EmployeeBenefits #Fintech #Cashless #HRTech #CommunityCommerce #SportsBusiness #FanEngagement #DX

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

The "Hotron Non-Contact Switch" allows you to open and close doors without directly touching door knobs or switches, making it hygienic! You can choose from two types: the "Hand Wave Sensor," which only requires you to wave your hand, and the "Foot Switch," which only requires you to place your foot at the entrance. It reduces the risk of virus and bacterial infections in places where hygiene is a concern, such as food factories, restaurants, hospitals, and nursing facilities. 【Features】 ○ Reduces the risk of virus infection by allowing door operation without contact ○ A wide variety of options to choose from based on application and location ○ Ideal for places where hygiene is a priority, such as food factories and medical facilities ○ Prevents unnecessary detection due to the switch mechanism 【Product Lineup】 ■ Hand Wave Sensor Series ○ Exposed waterproof type, front, down, and side-facing types "PF-R5" ○ Exposed type, front-facing type "PF-R1" ○ Embedded type, front-facing type "PF-U2" ○ Exposed type, downward wide type "PF-R4" ■ Foot Switch Series ○ Slim type with wide opening, vertical beam type "PF-01S" ○ Slim type with wide opening, horizontal beam type "PF-03S" ○ Standard type, horizontal beam type "PF-05" ◎ For more details, please download the catalog or contact us.
