[Video Now Available] What is buffing? Buff Grandpa's Craftsmanship Part 1 - Polishing Mysterious Items!

ユー・コーポレーション ユー・コーポレーション
Acrylic (PMMA) and polycarbonate (PC) tend to whiten and become cloudy on the surface when machined. However, by using a buff polishing method for mirror finishing, we can reproduce a clearer transparency! Our skilled technicians perform buff polishing by hand, and we have received high praise from our customers for the quality of our work. If you are having trouble with mirror finishing on resin products, please feel free to contact us. *For more information on buff polishing, please watch the video at the URL below! At You Corporation, we achieve micron-order ultra-precision machining of resin and metal materials through our years of accumulated know-how and high-precision equipment environment. We handle a variety of resin machining, including PC, acrylic, PPS, and PEEK, as well as metal machining for stainless steel, titanium, Inconel, and Kovar at our own factory. If you are facing challenges with complex shapes, tight deadlines, or cost issues, please consult with us!

Thank you for visiting the [Mechanical Components Technology Exhibition] and notice of free technical consultations and prototype acceptance for "release agents, sliding, and corrosion prevention."

  • NEW
  • COMPANY

Hello everyone! We are Nikken Coating Industry Co., Ltd., a specialized manufacturer of contract processing for fluororesin coatings and PEEK coatings. Thank you very much for visiting our booth at the recent "Mechanical Elements Technology Exhibition." Thanks to you, we were able to conclude the event successfully. At the exhibition, we proposed surface treatment solutions for the "five challenges (release, sliding, corrosion resistance, impurity measures, and environmental response)" that arise in manufacturing sites. Were there any technologies that caught your interest? ■ We are currently responding to inquiries made at the venue We are sequentially contacting those who made technical inquiries or requests for prototypes at our booth on the day of the event. If you have requests such as "I would like you to look at additional drawings" or "I need a quote urgently," please feel free to let us know. ■ For those who could not attend the exhibition or missed our booth We also welcome inquiries from customers who could not come to the venue, such as "coating for special shapes that other companies have declined" or "switching from existing coatings." If you have any concerns regarding "surfaces," please feel free to consult or contact us.

Dust from wood processing with a drill press.

Maintenance Resilience 2026: We will exhibit a fine particle visualization system at the 52nd Plant Maintenance Show. (July 15 (Wed) - July 17 (Fri), 2026 / Tokyo Big Sight, East Hall 1, 1-H12)

  • NEW
  • OTHER

The particle visualization technology developed under our brand "ViEST" has a very high level of detection sensitivity that allows for real-time visualization of the suspended and adhered states of micro and nano-sized particles. We are engaged in the sale of visualization systems and contract services for evaluation (investigating particles and airflow in production processes, manufacturing equipment, and factory environments, evaluating the performance of cleaning products, proposing yield improvement measures, etc.) both domestically and internationally. In manufacturing environments, invisible fine foreign substances, dust generation, particle adhesion due to static electricity, and airflow disturbances can lead to quality defects and reduced yield. Our company clarifies these contamination factors through visualization technology and provides consistent support from identifying the source of the problem to considering and confirming improvement measures. Do you have any of the following concerns? - Unable to identify the cause of foreign matter contamination - Want to check airflow and cleanliness in clean rooms - Want to understand dust generation from manufacturing equipment and transport systems - Want to reduce particle adhesion to films and substrates - Want to improve contamination that causes yield reduction

Metal Crack Repair: MS Method for Repairing Cracks and Fractures in Machinery Equipment

  • NEW
  • CATALOG

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
