Seidensha Electronics Co., Ltd.(Arakawa Ward)
Established in 1924 (Taisho 13), Seidensha Electronics Co., Ltd. is a company with a long history. It is the largest company in Japan in plastics welding equipment and resin processing equipment. We have interviewed Mr. Noriaki Matsugishi, who is the president of the company, which leads the world as a pioneer in the industry, and is located in Arakawa Ward, Tokyo.
In 1924 (Taisho 13), we began as a wired and wireless communication instrument manufacturer. We established Seidensha Seisakujo in 1953 (Showa 28), and in response to the development of plastics industry, we developed and produced “High Frequency Welders,” which bond plastics and similar materials. This machine recorded explosive sales for production of toys, such as inner tubes and soft vinyl dolls, which took the world by storm. Since then, we developed our business with welding processing techniques as our main expertise, and the “Ultrasonic Plastic Welder” developed in 1961 (Showa 36) became the world’s first machine to weld plastics with ultrasound. Today, we provide various products as the top manufacturer of devices that weld and fuse plastics and metal by making full use of applied technique of pulsed energy. As a recent example, we developed and produced machines for producing balloon catheter for medical use, which used to be dominated by products made overseas. We had these machines installed at domestic manufacturers, and our customers were satisfied that we were able to establish a production system that would be able to compete with prices overseas. Our machines are used for many of the products we use daily, such as bumpers and interior inside cars, cellular phones, digital cameras, masks, diapers, etc., and we can see them everywhere. Currently, we have about 150 employees, and more than one-third of our employees are engaged in development in some way. Many employees, with passion for manufacturing and skilled development capabilities, continue to research, develop, and produce machines that fit our customers’ purposes.
We possess various techniques for weld processing, such as “ultrasound,” “high frequency,” “laser,” etc. Although there are other companies specializing in one of the processing techniques, our advantage is the wide range of techniques and proposing skills, which enable us to respond to different needs of customers. We receive many requests from our customers asking for consulting such as, “We would like to process ___, but how could we handle this?” instead of, “We would like to have ___ welded,” and we work for solutions including processing method to techniques and model selection, and also taking customer’s opinions into account. For this reason, we have a dedicated test room at the head office where we can conduct various weld processing, so that our customers can see it with their own eyes and be satisfied. Our customers are satisfied, because they are able to directly see the techniques and are able receive custom proposals that meet their needs, when they are not able to completely understand from catalogs and websites. We deal with everyone who comes to consult with us with a strong attitude, “We won’t waste your visit.”
For a company like us dealing with customers from various industries and producing products domestically, it is a big merit to be located in Arakawa Ward. For example, since JR Nippori station is nearby and is accessible to Narita International Airport, customers with business overseas can stop by casually to see our techniques and have a specific consultation with us. Being close to Asakusa and Akihabara, which are popular places, also becomes an advantage for a business talk. In addition, although we work on industry-academia joint research with universities around Kanto region, such as University of Tokyo, Tokyo Metropolitan University, and University of Tsukuba, and around other provinces such as Tohoku University, we are able to collaborate smoothly due to the developed transportation network in the Tokyo metropolitan area. Chiba, Saitama and Ibaraki Prefectures became closer due to the increase in train lines in Arakawa Ward, such as Tsukuba Express and Nippori-Toneri Liner. Since this makes it possible to live in more affordable areas compared to downtown Tokyo, it is popular among our employees. We would like to support Japan’s “manufacturing” by continuing to produce “Seidensha-brand” here in Tokyo, as a company having Japan’s largest production capacity in the industry of fabrication equipment of plastic products.
