PLUS Electric Co., Ltd.

PLUS Electric Co., Ltd. (株式会社プラス電機) is a Japanese research-and-development-oriented manufacturer headquartered in Hamamatsu, Shizuoka Prefecture. The company designs and builds industrial robots and factory automation systems, with a particular specialization in aluminum casting equipment. Its product range includes automatic pouring robots for aluminum casting, aluminum wheel gate-breaking machines, NC automatic cutting machines, handling robots, and the FA/CIM systems that integrate these machines. The company also develops remote monitoring and control devices, optical multiplex transmission terminal blocks, and educational training equipment. According to its official website, PLUS Electric positions itself as an R&D-driven enterprise that responds to customer needs with self-developed products. Its core strength lies in control design for FA/CIM systems and in the development of remote monitoring and control devices that apply information network technology. The company provides many custom automatic control systems on commission from engineering and manufacturing firms. Its casting robots are designed to improve the harsh, high-temperature working environment of casting, reduce worker fatigue, and eliminate quality variation by reproducing the motions of skilled workers through teaching. The robots offer freely adjustable pouring volume, simple operation, easy teaching changes, heat resistance, robustness, and host-computer communication. The company was founded as a business in November 1969 (Showa 44) and incorporated in December 1971 (Showa 46). It is led by representative director Norio Uetaki (上滝憲夫). Its main bank relationships are with the Shizuoka Bank Mikatagahara Branch and the Hamamatsu Shinkin Bank Mikatagahara Branch. Its primary customers are described as aluminum casting plants worldwide. The company holds patent No. 3121919 for an automatic pouring device and control method for injecting molten metal into multiple molds. PLUS Electric's product line also includes an LED circle display that connects to a PC for real-time display, internet-connected news/weather/time display, and a patented bidirectional optical slip ring for reliable data transfer to rotating parts. The company offers manufacturing, repair, maintenance, and periodic inspection services. It is registered with the NC network and listed on the robot introduction matching site "Robokaru."

PLUS Electric Co., Ltd. was founded as a business in November 1969 (Showa 44) in Hamamatsu, Shizuoka Prefecture, and was formally incorporated in December 1971 (Showa 46). The company describes its history as a history of technology and development, continuously advancing toward the needs of the future. From its base in Hamamatsu, PLUS Electric developed a specialization in aluminum casting automation. It created automatic pouring robots for aluminum casting, gate-breaking machines for aluminum wheels, NC automatic cutting machines, and handling robots. These products were designed to address the harsh, high-temperature, labor-intensive conditions of casting work, improving the working environment and reducing quality variation caused by worker fatigue. The robots use teaching to memorize and repeat the motions of skilled workers, with easy teaching changes to accommodate various production changes. Over time, the company expanded into broader factory automation and CIM (computer-integrated manufacturing) system design and manufacturing. It developed remote monitoring and control devices applying information network technology, and optical multiplex transmission terminal blocks using optical communication technology. It also produced educational training equipment that mirrors real production machinery, including a tropical fish robot for educational use. In October 2007, the company announced a model change for its casting pouring robot control device. Due to the discontinuation of production of computer-related LSI chips, PLUS Electric had been notified three years earlier, stockpiled several years' worth of chips, and simultaneously began developing a new type. After a year of test trials, the model change was implemented from July 2007. The new control unit offered improved processing speed, functions, and performance while maintaining the same handling and specifications as the previous type. The company holds patent No. 3121919 for an automatic pouring device and control method for injecting molten metal into multiple molds. It is registered with the NC network and has been listed on the robot introduction matching site "Robokaru." Its main customers are aluminum casting plants worldwide, and it provides custom automatic control systems on commission from engineering and manufacturing companies. The company is led by Representative Director Norio Uetaki.
