Due to the ample temperature range, it is possible to completely remove impurities, including areas where the temperature is less likely to rise.

To promote crystal growth without allowing hydrogen molecules to enter the grain boundaries, a high vacuum environment was necessary. Additionally, to achieve secondary recrystallization of potassium-doped tungsten, it was also required to heat the workpiece itself to over 2000°C. As a result, we developed the equipment in-house. The first model achieved a work temperature of up to 2000°C, and the subsequent third model reached up to 2800°C. This equipment is utilized not only for the manufacturing of halogen lamp components but also for various manufacturing processes that require ultra-high temperature treatment. In particular, it has become indispensable for the removal of strong impurities, such as alumina for medical components and electrodes for ultra-high pressure mercury lamps. *For more details, please refer to the external link page or feel free to contact us.

Conducting genuine trial and error with agility! Our approach to development.

To achieve low-energy discharge, the electrodes must be made of materials with a low work function. One method is to add oxides and manufacture them through sintering; however, if there are too many oxides, the sintering temperature for tungsten may differ, which can result in insufficient sintering conditions. In such cases, tungsten alone can meet the necessary sintering conditions and maintain its physical properties at a high level. Subsequently, emitters that have been manufactured separately and can add easy discharge properties are impregnated into the sintered tungsten, ultimately resulting in a state where both are physically and chemically bonded. To realize this, hundreds or thousands of patterns must be repeatedly experimented with and developed. This diligent trial-and-error approach, carried out with agility, is the attitude and characteristic of our company's development efforts. *For more details, please refer to the external link page or feel free to contact us.*

Considering the required characteristics as appropriate, optimize the selection of raw materials, mixing, and sintering conditions for development and manufacturing.

Alumina ceramics cannot be sealed using a bonding method like glass, so instead, a method is generally employed where frit glass is melted and poured into the small gap between the electrode and the valve to seal it. Therefore, the electrode materials in the sealing area require conductivity, high-temperature resistance, and halogen resistance, and it is also necessary to ensure that there is an appropriate thermal expansion coefficient relationship between the frit glass, alumina valve, and electrode. Considering the required characteristics of alumina powder and Mo powder (or W powder), the selection of raw materials, mixing, and sintering conditions are optimized to develop and manufacture conductive materials. When the melted frit glass flows into the small gap (capillary) due to capillary action, factors such as the surface roughness of the developed materials are also taken into account, and processes like centerless grinding are performed for finishing. *For more details, please refer to the external link page or feel free to contact us.*

In a factory with a variety of products and small quantities, "things are not progressing as planned" — the cause lies in managing it with the same mindset as mass-produced items. By taking a "zoom-out" perspective from TOC (Theory of Constraints), we will fundamentally review the production system. An online seminar with real case studies effective for processing and assembly-type production management in aerospace, machinery, and more. November 10 (Monday) 16:00 - 17:30 / Free participation.
