[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!

Truck berth vehicle detection

It's not too late to address the "Logistics 2024 Problem." Why not immediately reduce drivers' waiting times?

  • NEW
  • PRODUCT

Are you making progress on measures for the "2024 Problem"? With stricter management of drivers' working hours, reducing "waiting time" has become an urgent issue in the logistics field. To address this challenge, our company, Hotron, proposes the "Vehicle Detection Ultrasonic Sensor 'HM-UX2'," which instantly grasps the availability of loading bays. The 'HM-UX2' contributes to the resolution of waiting times by accurately understanding the availability situation, reducing unnecessary waiting and queueing, and shortening waiting times to alleviate the burden on drivers! By replacing the "eyes" of your loading bay management with this high-precision sensor, why not start addressing the "2024 Problem"? Take a look at the product features: "Can it accurately detect availability?" "Can we really use it in our company?" "I just want to know the cost, even if it's an estimate." If you have any questions or requests, please feel free to consult with us.

Non-contact light touch sensor "HA-T401/HA-T520"

A non-contact light touch sensor "HA-T Series" that realizes "wanting to open in a narrower range and in a limited manner" based on the surrounding environment of automatic doors.

  • NEW
  • PRODUCT

The non-contact beam touch sensor "HA-T401/HA-T520" has a compact detection range, making it an ideal automatic door sensor for installation on automatic doors facing narrow corridors or busy streets. Depending on the application and installation location, you can choose between "non-vision mounting type" and "non-vision built-in type." 【Features】 ● With the beam touch sensor, you can open and close the automatic door simply by bringing your hand close without touching it, ensuring hygiene. ● Depending on the installation environment, such as single sliding or bi-parting doors, the detection range can be set in four ways: left, center, right, with 4 spots and 12 spots settings. ● Two types of activation row settings are available to reduce unnecessary opening and closing of the automatic door due to cross traffic, contributing to energy-saving effects. ● The touch switch and infrared sensor are integrated, allowing for a switch between beam touch and infrared sensor modes with a single model. 【Recommended for such places!】 ☑ Entrances facing busy corridors ☑ Counters or signs near the door ☑ Buildings facing narrow corridors ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors ◎ For more details, please download the materials or contact us.

HK-2

Recommended for earthquake measures for automatic doors and equipment! Seismic device HK-2.

  • NEW
  • PRODUCT

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.
