Heat wave measures × Safety for factory workers × Rising electricity costs. "Factory/Warehouse Heat Exhaust Eco Louver" that exhausts heat without using electricity, released by Sahara Co., Ltd. on April 1.
Temperature-Sensitive Louvers Utilizing Shape Memory Alloy Technology Sahara Co., Ltd. (Headquarters: Ichinoseki City, Iwate Prefecture) launched the natural exhaust ventilation device "Factory/Warehouse Exhaust Eco Louvers" on April 1st, aimed at solving the problem of heat accumulation indoors in large facilities such as factories, warehouses, and logistics centers. In recent years, Japan has experienced rising temperatures during the summer, making indoor temperature increases a significant issue in large spaces like factories, warehouses, and logistics centers. Particularly, the accumulation of heat near the roof leads to problems such as deteriorating working conditions, increased load on equipment, and rising air conditioning costs. However, when introducing ventilation systems or large fans, the costs for equipment and electricity often increase, resulting in many cases where adequate measures are not taken. To address these challenges, Sahara Co., Ltd. has developed the "Factory/Warehouse Exhaust Eco Louvers," which exhaust heat using natural forces without consuming electricity. ■ Product Features - Natural exhaust ventilation that requires no electricity - Temperature-sensitive opening and closing using shape memory alloy (limited to temperature-sensitive type) - High-durability aluminum structure - Louver design that minimizes rainwater intrusion - Compatible with retrofitting to existing facilities - Suitable for wooden, steel, and ALC structures

School Gate Security Feature - Protecting Lives with the "Outdoor Gate Electric Lock System"
Did you know that many of the recent unauthorized school intrusions by suspicious individuals are actually due to "entry through unlocked school gates"? In the 2001 Ikeda Elementary School incident, the perpetrator stated that he attempted to enter after seeing an open gate. The gates leading to school premises are the first line of defense that should be strengthened to prevent unauthorized access. Lockman Japan proposes creating life-saving systems for such gate security. Special page for school gate security 【Outdoor gate electric lock system】: https://www.lockman.co.jp/product/new/9092/ 【Three key points】 - Ensure the gate is securely locked except during school hours - Unlocking from outside is done with a password or card key - Visitors are verified at the staff room, and remote unlocking is also possible 【What this system can do】 - Achieve reliable locking while allowing smooth entry and exit - Integration with surveillance cameras - Ensure quick evacuation routes in emergencies Automatic locking prevents forgetting to lock and stops unauthorized access. It operates reliably even in outdoor gates exposed to rain. The special page provides detailed information on system configuration and features of each product, so please take a look.

Don't give up just because it's a small quantity! We can handle everything from a single cast part to mass production. Castem will exhibit at the Monozukuri Fair 2026.
Castem Co., Ltd. will exhibit at the "Monozukuri Fair 2026" held at Marine Messe Fukuoka from October 14 (Wednesday) to 16 (Friday), 2026. "Small lots are not suitable for casting" and "You can't make a casting with just one piece" — Have you given up on producing cast parts for such reasons? At this exhibition, we will introduce three casting methods that can be selected according to application and quantity, as well as MIM (Metal Injection Molding) suitable for fine and thin-walled parts. We will propose the optimal manufacturing method tailored to your needs, from prototyping and development of metal parts to small-lot production and mass production. We welcome inquiries such as "Can this part be cast?" and "Can you accommodate small quantities?" In addition to samples of each method, we will also display a dragon sculpture that poses a high casting difficulty. You can experience Castem's technological capabilities on-site. Please visit the Castem booth. 【Exhibition Overview】 Exhibition Name: Monozukuri Fair 2026 Date: October 14 (Wednesday) to 16 (Friday), 2026, 10:00 AM to 5:00 PM (until 4:00 PM on the last day) Venue: Marine Messe Fukuoka Hall A (7-1 Okihama-machi, Hakata-ku, Fukuoka City, Fukuoka Prefecture) Exhibition Booth Number: AE-38
