We will be exhibiting at the 3rd [Kyushu] Semiconductor Industry Exhibition!

Solve delays, damage, and operational errors in overseas-made valves with domestic products! We are currently offering three successful case studies that balance operational efficiency and safety for free!

Are you facing challenges such as "it takes time to respond to substance content investigations," "managing 4M changes is difficult," "there are many instances of damage and leaks," and "there is a risk of accidents due to operational errors"? With Hamai's domestically manufactured ball valves, we achieve quick responses and stable quality through integrated production from procurement to assembly. In fact, many major manufacturers have seen improvements in operations and accident prevention. ▼ Case Studies - Construction machinery manufacturer: Contributed to a significant reduction in damage issues and zero accidents. - Oil plant manufacturer: Eliminated labor accident risks by preventing operational errors. - Semiconductor manufacturing equipment manufacturer: Submitted investigation documents within a week, greatly reducing the burden of quality control. For more details, please check the "Download Catalog" link below.

Contributing to the improvement of on-site safety! With a spring-type locking mechanism, it securely locks out semiconductor manufacturing equipment and facility piping. Prevents accidental opening and closing due to contact or vibration.

A full-bore equivalent ball valve with a key lock function added via a sleeve, based on the TSS-01 model. It is oil-free and compliant with the RoHS directive (10 substances). It ensures reliable locking in fully open and fully closed states, making it effective for safety measures in semiconductor manufacturing equipment and similar applications. Produced in our domestic factory using Hamai's latest valve technology. ■【Features】 - Ideal for lockout of semiconductor manufacturing equipment and facility piping - Reliable locking in fully open and fully closed positions due to the spring-type locking mechanism - Capable of locking in various installation locations, including vertical and reverse piping - Full-bore equivalent specifications that can handle large flow rates ■【Product Quality Recognized by Professionals】 Hamai's ball valves have a proven track record of mass supply (OEM) to various industrial equipment and machine tools, primarily for major manufacturers, making them top-class high-performance ball valves in the industry.

We will hold a "3D Manufacturing Individual Consultation Meeting" at creative centers across various locations. On the day, we will be available to discuss "3D modeling machines." A dedicated staff member will be present, allowing for in-depth discussions unlike at exhibitions. Each session is limited to one company, and we will provide careful, one-on-one support. As seating is limited, please apply early. All of our staff sincerely look forward to your visit. Recommended for customers like these: ■ Using a 3D printer but dissatisfied with accuracy or finish ■ Wanting to create mock-ups closer to the final product ■ Looking to in-house production of jigs ■ Interested in utilizing it in educational institutions Capacity: Limited to one company per session Application deadline: 17:00 on the business day before each event date.

Date and Time: Thursday, July 23, 2026, 13:30 – 16:45 This seminar is recommended for those who use "Gaussian," the de facto standard for quantum chemistry calculations, and "GaussView6," which is essential for creating input files and visualizing results, but want to learn more effective settings and convenient features. We also offer a free attendance benefit for those who have contracted paid support. Please make use of this for advanced research and data-driven development!
