[Providing Case Studies] Are you struggling with fastening resin parts? You can understand the benefits of using the high-torque resistant and strong pull-out insert nut "SSOO Nut."

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)
We would like to introduce a document summarizing case studies of SSOO nuts. SSOO nuts are 'heat-pressed insert nuts (outsert nuts)' that achieve high "torque resistance" and "pull-out strength." They prevent nut rotation (slipping) and pull-out that can occur during high-torque tightening, ensuring safe fastening of plastic products. The features of SSOO nuts have solved various problems for our customers. [Case Study 1] - High tightening torque is required, but the insert nut rotates. → Meets tightening requirements with high torque resistance. Fastens plastic components without rotation. [Case Study 2] - Want to reduce the number of screws used for weight reduction. → Achieves a reduction in the number of screws while ensuring fastening strength with high pull-out strength. Additionally, we have realized many benefits, including reducing environmental impact and responding to strong vibrations. For more details, please download the document or feel free to contact us.

[Case Study] You can understand the reasons for adopting high-torque insert nuts.

You can see the benefits of using the "SSOO Nut," an insert nut that is strong against pull-out and supports high torque. Examples of parts and molding methods are currently being published.

The SSOO nut is a "heat press-in type insert nut (outsert nut)" that achieves high "torque resistance performance" and "pull-out strength." It prevents the nut from rotating (spinning) or pulling out during high torque tightening, ensuring safe fastening of resin products. The SSOO nut has solved various problems for our customers. 【Case 1】 - High tightening torque is required, but the insert nut spins. → It meets tightening requirements with high torque resistance performance, fastening resin components without spinning. 【Case 2】 - To reduce weight, we want to decrease the number of screws used. → It achieves a reduction in the number of screws used with high pull-out strength while ensuring fastening strength. Additionally, it has realized many benefits such as reducing environmental impact and responding to strong vibrations. For more details, please refer to the "SSOO Nut Adoption Case Collection." If you are struggling with fastening resin at high torque, please take a look at the materials. You will understand why we were able to develop the original SSOO nut that can handle high torque tightening. Please check it out from the link.

SSOOボルトカタログ.JPG

Insert bolt that can be tightened without breaking the resin of "SSOO Bolt".

A high-torque compatible embedded bolt for resin that is strong against rotation and withdrawal, and does not damage the resin. It allows for nut tightening when embedded in resin parts.

The "SSOO Bolt" is a resin embedded bolt (insert bolt) with a special octagonal head shape, offering excellent torque resistance and pull-out strength. An insert bolt is a bolt that is embedded in resin and fastened with a nut. By tightening with a nut, it allows for the fastening of resin parts to each other or resin parts to metal. It minimizes deformation and cam-out of the resin when fastened with high torque, enabling nut tightening at high torque levels. It can also be used for back embedding (thermal press fitting), making it suitable for shapes that cannot be integrally molded. Since the bolt can be used in an upright position within the resin, it improves the assembly of parts. The product design has been completely revamped, and sizes from M4 to M8 are now available. 【Features】 ● Special shape that minimizes cam-out and slip even when tightened with high torque ● Strong against pull-out, preventing deformation of resin parts ● Usable for both insert (simultaneous molding) and outsert (thermal press fitting) ● Mass production possible due to unique manufacturing methods ● Trusted Octa Lobular series *For more details, please refer to the materials. Feel free to contact us with any inquiries.

HK-2

Recommended for earthquake measures for automatic doors and equipment! Seismic device HK-2.

  • NEW
  • PRODUCT

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.

PERI products are used at construction sites around the world. (Poland: Construction work on the Dunajec Road Bridge)

  • NEW
  • COMPANY

PERI products are used at construction sites around the world. This time, we would like to introduce the construction work of the "Dunajec Road Bridge" spanning the Dunajec River in the town of Nowy Targ in southern Poland. The road bridge was planned to be constructed using a balanced cantilever method, dividing the cantilever beams starting from each pier into 10 segments. A particular concern was to strictly adhere to the concrete pouring cycle for each segment. To achieve this, a balanced cantilever carriage (VBC) equipped with a hydraulic advance system and an automatic formwork stripping function was adopted. By utilizing the VBC, it became possible to pour concrete for segments up to a maximum length of 5 meters in a single cycle, allowing for efficient and timely construction. PERI products: 1. TRIO Panel Formwork 2. VARIO GT24 Wall Formwork 3. PERI UP Flex Modular Scaffold 4. VST Heavy-Duty Shoring Tower PERI Japan Co., Ltd.
