This is a twin-screw extruder for the "Laboplast Mill," a mixing and extrusion molding evaluation testing device that employs a segmented screw design.

● It is a segment system that allows for free reconfiguration of the screw. ● By combining screw segments, you can adjust the strength of mixing and change the mixing zones. ● It is equipped with a vent port and a side feeder hole that allows for sample supply from the middle. ● The screw rotation speed is twice the motor's set rotation speed, enabling high shear mixing. ● Since it rotates in the same direction, it has self-wiping properties.

In public construction civil engineering sites, there are many instances where sheets are used as common temporary facilities, such as construction roads, access roads, heavy machinery work yards, material storage areas, and worker pathways. Traditionally, steel plates were common, but due to their weight, transportation and installation can be cumbersome. Hyper CLT sheets are civil engineering materials made from wooden CLT for civil engineering use. The 5×10 sheet weighs about 230 kg, and the 5×20 sheet weighs about 460 kg, making them lightweight and easy to transport, install, and remove, even with small machinery. They can be widely utilized for temporary roads, heavy machinery scaffolding, pathways within the site, and protection of material storage in public works. Since they are made of wood, they also contribute to environmental aspects such as reducing summer heat reflection, lowering noise, and fixing CO2. They can simultaneously address construction efficiency, safety measures, and environmental considerations, making them effective for innovative proposals in public works. Furthermore, they improve transportation efficiency and reduce labor in site operations as an alternative to steel plates. Hyper CLT sheets are registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A." They are recommended for companies considering civil engineering, civil engineering use, and civil engineering CLT. Feel free to request materials or consult about implementation. They are temporary materials that also help improve site evaluations in public works. Please consider them.

We have released a new video on our company’s YouTube channel. The theme of this video is "The World of Amino Acid-Based Shampoos." Amino acid-based shampoos have become popular in recent years, but the lather, feel, and finish can vary greatly depending on the cleansing ingredients used. In this video, we clearly explain the changes in user experience based on the differences in cleansing ingredients by comparing two types of amino acid-based shampoos. We hope you can use this as a hint for developing original shampoos and differentiation.

New York and Tokyo, June 26, 2026 - (JCN Newswire) - This year's successful listing of PayPay Corporation (hereinafter "PayPay") on NASDAQ has provided a significant boost. The question now facing Japan's leading innovation companies is no longer "Is a U.S. listing feasible?" but rather "How can we attract global capital and build companies that align with global growth strategies?" The 2nd Japan Go IPO Summit will be held on September 16, 2026, at the Grand Hyatt Tokyo to address this question. This summit is hosted by MarcumAsia and organized by AUM Advisors.
