What is Iiyama Precision Glass?

Iiyama Precision Glass is a manufacturing company founded in 1941 that specializes in precision glass processing. As one of the "manufacturing factories" that have supported Japan's manufacturing industry since the postwar period, we have contributed to the development of various research and manufacturing fields, including optics, semiconductors, electronic parts, and medical and chemical products.

Of course, as times change, the technology required also becomes more advanced. We are contributing daily to cutting-edge product development in various fields, leveraging the strengths we have cultivated since our founding, the experience we have accumulated, and the trust we have earned from our customers. We will continue to strive to create products that we are proud of as a specialized manufacturer and to take on new challenges.

STRONG POINT

Iiyama Precision Glass 4 strengths

Since its founding in 1941, Iiyama Precision Glass manufacturing has been supported by four strengths
that have been cultivated for a long time and have progressed daily with the company's motto of "is it the best?" in mind.

Flexible and light-footed production system

Iiyama Precision Glass first strength is its production system that can flexibly respond to customer requests and needs.

Various needs arise in the research and development of manufacturing. Among them, there are many requests to make "just one" precision part that requires special processing, or to deliver it by a specified date. We have sincerely listened to such voices and have striven to respond flexibly.

In addition, we are highly evaluated for our light-footedness, with sales and manufacturing integrated, which allows us to quickly grasp the needs of companies conducting cutting-edge technological research and development and quickly respond to difficult requests.

Reliable quality control based on data

The second strength of Iiyama Precision Glass is accurate measurement technology and quality control based on data obtained from the measurement results.

Our manufacturing is based on the idea that "what we process ourselves needs to be guaranteed." When shipping products, we submit measurement data along with them, and have earned the peace of mind and trust of many customers.

To achieve this, not only advanced processing technology but also post-processing measurement technology is essential. Iiyama Precision Glass actively invests in precision measuring equipment and constantly improves the skills of the engineers who use it, adding added value and appeal in the form of "peace of mind" through quality assurance.

Horizontal connections cultivated over many years

Iiyama Precision Glass third strength is the network of partner companies that it has cultivated over many years.

We handles the entire process of "material procurement → processing → polishing → quality assurance" in-house.However, there are many different needs for precision glass products, and in order to fully meet those needs, "horizontal connections" with partner companies are essential.

We will continue to work with multiple companies that specialize in specialized processing that cannot be done by a single company, and strive to create cutting-edge products that meet our customers' needs.

Consideration and efforts for environmental conservation

Iiyama Precision Glass fourth strength is its efforts for environmental conservation.

In specialized manufacturing sites, it is not uncommon to use chemicals or glass materials containing heavy metals. If no measures are taken, the waste generated will cause environmental pollution,leading to damage to the human body and nature.

As a manufacturing company, we at Iiyama Precision Glass manage the waste and wastewater discharged from our factories in detail. This includes cooperating with the recycling of ordinary waste and installing the latest wastewater treatment facilities to purify wastewater containing lead.
