Nagai manufacturing Co., Ltd.

We have built up a track record in Japan and abroad by applying our unique engineering plastic forming method.

Our company manufactures and sells products made by forming engineering plastics. Our main products are insulation covers for stepping motors and capacitors, reflectors for medical equipment, printers and LED devices, and speaker diaphragms for automotive and IT equipment. We have many customers in Japan including Foster Electric, Namiki Precision Jewel, and Tohoku Pioneer. We have experience in delivering our products overseas to Japanese and Korean companies. We developed a matched mold forming method that features higher mold shape reproducibility than other forming methods. Our company has been applying this method to manufacture formed products from thermoplastic films and increase our business capacity.

[Company strength]
Our matched mold forming method (registered tradename FILMOLD) is a unique technology. Our advantage is that we possess this forming method. We can form materials that are about 12 to 500 μm thick. We can also make use of the characteristics of upper and lower molds to form materials such as woven cloth, nonwoven cloth, and paper. Another advantage of our company is our capability to produce formed products that are differentiated from other articles. We provide reliable products to the world by making use of our reliable technology and quality power that we have accumulated to date. We have the strength to make proposals capable of satisfying various needs. We take pride in our strong connections to material manufacturers and our extensive information about materials. Our company has already obtained ISO 9001 and ISO 14001 certification. Nomex, QMS, and EMS have all been settled and are now functioning as business tools. We also have a history of direct trading with overseas companies for more than 20 years and we are familiar with export work.

[Business description]
Our company applies our in-house 3D precision forming technology to manufacture and sell products formed from thermoplastic engineering plastic films. Our formed products are used in a wide range of applications. These include covers for stepping motors and capacitors, reflectors for medical equipment, printer and LED parts, and speaker diaphragms for automotive and IT equipment. We sell them directly to manufacturers of home electronics appliances and electronic parts in Japan and abroad.

3D precision forming (various engineering plastics); formed product sales

[Strength of products/technologies]
Our FILMOLD matched mold forming method has a number of features. It is suitable for precision parts because the mold shape reproducibility is higher than any other forming method. The mold cost is lower than injection molds, and trial molds are applicable to mass production as they are. Our method enables quick mold production and delivery, which is usually within three weeks, and our deep drawing includes vertical startup. Our vacuum formed products are mainly used for packaging materials, such as containers and trays. Our processed products are applied to high-added-value uses because they are used as functional parts. Our company is enhancing support for customer needs on the basis of this forming method.

[Representative's message]
Our company has been consistently engaged in engineering plastics forming since our establishment. We started our company by establishing a processing method for crystalline polyester (Tetoron) films, which had been considered impossible to form. Our first product was a center cap for a speaker for a radio-cassette recorder. We have been improving our processing technology for 40 years since then, mainly by manufacturing speakers. We can now form a remarkable number of kinds and shapes of films. However, it is not generally known among the public that plastic films can be formed with high accuracy in three dimensions. We will widely introduce our technology through various media outlets and provide our products to all kinds of markets that require precision and fine shapes.

[Company structure for market development/overseas expansion]
Our FILMOLD technology is not well-known to the general public, so we must first disseminate the features and advantages of this technology for sales channel development. Our company has been promoting awareness of our technology mainly through the sales department. We have been responding to inquiries received through our website, and also promoting dissemination of our technology through exhibitions, press releases to technical media, and advertisements. Our own activities are limited, so we often receive support for sales activities from various trading firms.

[Market share/Ranking]
We are the only manufacturer capable of using the matched mold forming method for producing thermoplastic resin formed products, and particularly electronic parts.
