Iiyama Precision Glass Co., Ltd.
We manufacture glass parts for visualization by precision glass processing.
Our company has a history of over 70 years as a precision glass processing manufacturer. We manufacture optical and electronic equipment parts by processing many kinds of glass materials and supply them to laboratories and manufacturing divisions in various fields. We have cultivated technologies and know-how through our history of devotion to manufacturing glass processed parts. Our company makes use of these resources to manufacture glass processed parts for trial articles or before mass production. We also manufacture many kinds of parts for semiconductor manufacturing equipment, liquid crystal exposure equipment, measuring equipment, and medical equipment, from even a single piece. We can quickly and flexibly meet customer requests at a low cost under our integrated production system from material procurement to cutting, forming, and polishing.
Product and technology information
[Product description] Glass has excellent characteristics that are not available from other materials. Glass is very transparent, has little thermal extension, is impassible to electricity, water or air, and is highly resistant to chemicals. We can make use of these characteristics to develop new technologies. We manufactured a glass product (shown here) for visual evaluation to meet a desire to view the engine interior at the development stage. We succeeded in making it possible to visualize combustion in automobile engines.
[Product description] We proceeded with technological development for ultra-high-precision polishing of the inner and outer sides of glass rollers and achieved these results. This was done under the New Product and Technology Development Support Project subsidized by Ota Ward. We noted that synthetic quartz is a new material that allows ultraviolet ray transmission. We tackled the development of ultra-high-accuracy (Å level) polishing technology to raise the surface roughness accuracy to 100 times the metal surface roughness or more. We also improved our peripheral polishing machine. We were able to establish an ultra-high-accuracy polishing technology capable of raising the surface roughness of a synthetic quartz pipe to 6 Å (Ra).
[Company strength] Our company has an integrated production system from material procurement to cutting, forming, and polishing. This system enables us to quickly and flexibly meet customer requests at a low cost. All of us are promoting environmental activities. We release factory effluent into public sewers after eliminating environmentally hazardous substances in our in-house wastewater treatment facilities. Our thorough environmental measures with wastewater management and waste management mean that we can process even lead glass, which is needed in cutting-edge fields of medicine and chemistry. [Business description] We are engaged in precision glass processing in Ota Ward, Tokyo. We manufacture optical and electronic equipment parts by processing many kinds of glass materials. We supply these products to laboratories and manufacturing divisions in various fields. We have been cultivating technologies through our history of over 70 years of devotion to manufacturing glass processed parts. Our company makes use of these technologies to manufacture glass processed parts for trial articles or before mass production. We also manufacture many kinds of parts for semiconductor manufacturing equipment, liquid crystal exposure equipment, measuring equipment, and medical equipment, even from a single piece. [Industry] Precision glass processing [Strength of products/technologies] Processing and also measuring technologies are indispensable to achieving processing accuracy high enough for ultra-high-precision glass parts. Quality cannot be assured without equivalent measuring technology, no matter how high the processing accuracy may be. Our company does not spare investment on precision measuring equipment. We provide reliability based on quality assurance as an additional value or attraction to researchers and other parties developing cutting-edge technologies. Our processing accuracy is as high as ±1 μm outside diameter tolerance, ±1 μm board thickness tolerance, λ/20 flatness, 3 Å surface roughness, and one second in parallelism and perpendicularity. [Representative's message] Our company was established in Ota Ward, Tokyo in 1941, in order to be a company that contributes to society through high-precision glass processing. Our company is highly appreciated at research and manufacturing sites in various fields. These include optical equipment, semiconductor equipment, electronic parts, and medical and physicochemical equipment. Every one of us shall continue to pursue and make progress toward what our company can do, following our company motto "Is it the best?" We are confident that this will enable our company to win customer trust. We will continue to manufacture products with pride to meet customer needs as a specialist manufacturer rooted in the local area. [Company structure for market development/overseas expansion] Our sales staff at the office and technical staff at the factory attentively solve customer problems. Our staff also visit customers as required. We also proactively attend exhibitions and introduce our cutting-edge processing technologies. [Market share/Ranking] We supply engine parts for visualization to almost all automobile manufacturers in Japan.
