Industry Customer Case Study Article No. 5: Rexxus Industrial Co., Ltd.

Attention those struggling with coolant tank cleaning! We will introduce a case that significantly reduced the burden of tank cleaning!

We conducted an interview with a customer who has introduced our products. The fifth installment features an article about Rex Industries, Inc., which boasts the top market share in Japan for pipe machines (thread cutting machines). ■ Rex Industries, Inc. ■ As a comprehensive manufacturer of piping equipment, Rex Industries specializes in the manufacturing and sales of piping tools and environmental equipment, and holds the top market share in Japan for pipe machines (thread cutting machines). They aim to create a comfortable working environment as a "working amenity creation company" and are committed to solving various troubles and challenges related to piping facilities. Their business includes planning, development, design, manufacturing, and sales of pipe machines, various cutting machines, fusion machines, copper pipe tools, diamond machine tools, and environmental equipment, as well as water treatment and hose (horse) amenity businesses. This time, we interviewed Mr. Tsutomu Terao and Mr. Yuichi Katagiri from the manufacturing department. We discussed the effects of introducing our filters in the sludge recovery and tank cleaning processes in the casting cutting and processing stages. As a result of introducing our filters, we received feedback that it led to improvements in the working environment, product quality, and workplace satisfaction and motivation. Please take a look.

Our company will be exhibiting at the "Fukuoka Future Manufacturing Technology Promotion Exhibition 2026," continuing from last year. We will showcase products centered around printing technology, including ASSY unit products, touch sensors, pressure-sensitive sensors, and functional products such as sheet switches, as well as decorative molded products, panels with new textures, UL labels, and outdoor marking films. Additionally, we have established a production system that allows for integrated manufacturing from planning to mass production, including printing processing, molding processing, and assembly of circuit board ASSY. We will have various samples and demonstration units available, so we kindly invite you to visit us. Event Dates: July 8 (Wednesday) to July 10 (Friday), 2026 (3 days) Hours: 10:00 AM to 5:00 PM (until 4:00 PM on the last day) Venue: Kitakyushu Messe (Formerly the New Hall of the West Japan General Exhibition Center) Address: 3-8-1 Asano, Kokurakita Ward, Kitakyushu City Organizer: Fukuoka Industrial Technology Promotion Exhibition Executive Committee

Our company has added new products "MRS-019" and "MRS-020BK" to the "MRS Coating" series, which exhibits excellent release properties for adhesives, resins, and adhesive tapes, intended for use in food contact applications. We propose these as a new option for environments where compliance with regulations and high release performance are both required for equipment and components that come into contact with food. The MRS Coating series offers a range of surface treatments that not only provide excellent non-stick properties but also feature solvent resistance and high hardness, which are not found in traditional silicone treatments. In food manufacturing processes that handle materials prone to sticking, such as rice, dough, and seasonings, it contributes to reducing adhesion issues, lowering cleaning burdens, and improving work efficiency. You can utilize this coating on metal components that come into contact with food, such as conveyor parts, hoppers, chutes, guides, plates, and components of filling and molding equipment.

Our company will be exhibiting at the largest agricultural and livestock exhibition in Japan, the "4th Kyushu Agricultural WEEK Livestock Materials EXPO," which will be held at Gran Messe Kumamoto from May 27 (Wednesday) to May 29 (Friday), 2026. This material is a new type that enables zero-energy cooling by converting heat into infrared radiation and emitting it into space, without using any external power. By implementing it on building roofs and outdoor electrical equipment, it helps suppress internal temperature rises, contributes to maintaining and improving food productivity, ensures stable operation of equipment, and reduces air conditioning energy consumption. It is being recognized as a new carbon-neutral technology. Due to its energy-saving performance, this material has received the 2025 Energy Conservation Award. We invite you to visit our booth when you come to the venue. Exhibition Overview: Dates: May 27 (Wednesday) to May 29 (Friday), 2026, 9:00 AM to 4:00 PM Venue: Gran Messe Kumamoto Our Booth Number: 5-66 (High-Temperature Countermeasures and Weather Risk Response Fair Zone) Moving forward, our company will continue to contribute to maintaining and improving food productivity through reducing internal temperature and air conditioning energy consumption, supporting Japan's agricultural and livestock industries as a behind-the-scenes player, and working on the evolution of product performance, durability, and application methods.

We are pleased to announce that our waterproof sheet "Innovation Proof RR," integrated with our radiative cooling material "SPACECOOL," has been introduced in two elementary schools in Setagaya, Tokyo. In recent years, the severe heat during summer has worsened the environment in schools. A report by UNICEF points out that high temperatures may affect school attendance rates and children's concentration. Additionally, in Japan, there have been many cases of heatstroke occurring during physical education and sports activities under school management, and the Ministry of Education, Culture, Sports, Science and Technology has reported that school sports activities are closely related to children's heat exposure risks. Furthermore, the heatstroke prevention guidelines for school sports specify criteria for exercise implementation based on the WBGT (Wet Bulb Globe Temperature), indicating that specialized management is necessary for activities in hot environments. As the need for heat countermeasures in schools has become more urgent than ever, we aim to contribute to creating a more comfortable educational environment for teachers and students by introducing our radiative cooling material "SPACECOOL," which cools spaces with zero energy, thereby reducing heat gain from roofs and lowering indoor temperatures in gymnasiums and school buildings.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who wish to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. You can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520" depending on the application and installation location. 【Recommended for such places!】 ☑ Entrance facing a busy corridor ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passages ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing, contributing to energy-saving by minimizing wasteful power consumption ● Equipped with a light touch function, allowing the door to open and close just by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.
