Glass is a material that provides a multitude of positive societal benefits. It can be customized by modifying its composition and altering the various forming and finishing processes used to manufacture the intended end product.
Since NEG’s establishment, we have dedicated ourselves to this material, seeking at all times to develop new glass compositions and advanced technologies for melting, forming, processing, and evaluation.

Glass that optimally meets the needs of customers with respect to characteristics, shape, grade, and precision is widely used in display devices, IT equipment, automobiles, buildings, and energy related fields, and the range of next-generation applications for this material continues to expand.

We are working to produce new forming technologies and combine them with technologies in other fields to create innovative applications. “Glass for the future”… that’s what our creative manufacture is all about.

By producing new types of glass, we endeavor to ensure harmony with the environment and contribute to the development of a sustainable society.

Glass Manufacturing Technologies

We have concentrated its efforts on developing core glass manufacturing technologies, ranging from material design to melting, forming, processing, and evaluation. All of our skills are utilized in the creation of our manufacturing equipment, which has supported the development of new technology.
Our glass technology allows us to create advanced functional products.


Material Design

Creating Glass with the Reguired Property and Functions
Glass is unique in that nearly any element can be incorporated as a constituent of this material. By altering its composition and achieving the necessary balance between its many properties, glass with superior functions is born. Optimal glass materials emerge from a repeated process involving modification of composition, test melting, analysis, and evaluation. Each resulting glass material has specific properties and functions. In this way, we have created several hundred types of glass benefitting all kinds of applications.


Analysis and Evaluation

We have developed analytical technology that enables accurate analysis of minimal amounts of hazardous substances in glass as specified in RoHS directives. Our Chemical Analysis Section received ISO/IEC 17025 certification in 2006. The results of analysis conducted by the certified entities are accepted globally and ensure the quality of NEG products.


Melting Technologies

Uniform and Efficient Melting
The raw materials for glass that have been blended together are heated and melted at over one thousand degrees in a melting furnace. High-quality glass requires precise furnace control technologies. In response to environmental concerns, we are increasing the number of oxy-fuel firing systems, the use of lowcarbon fuels, and the use of electricity in melting furnaces to curb carbon dioxide and nitrogen oxide emissions.


Forming Technologies

Molten glass is formed into sheets, vessels, tubes, or fibers, depending in specifications. A defining characteristic at NEG is our extensive use of forming technologies. We accommodate diverse needs, achieving high dimensional precision and production efficiency by using optimal forming processes for each product.


Processing Technologies

We also uses a wide range of processing methods which are bringing new functions and properties to glass. These include glass reforming by heating, crystallization via firing, and thin film coating on glass surfaces. In this way, glass is given even more precise shape as well as new functions and properties.


in the Glass Manufacturing Process

We were still a young company—only ten years old—when we made the bold decision to pursue products including fluorescent lighting tubes, x-ray shielding glass, glass blocks for construction, and cathode-ray tubes for televisions and scientific observation. This required a rapid leap forward in our manufacturing capacity, and that advancement, as well as the decision to specialize in developing high-tech glass, have played a major role in improving quality of life for people around the world and created the globally recognized company that NEG is today.
