In order to expand production at Mabuchi Taiwan Co., Ltd., in October 1973 a new factory was constructed and existing production facilities were modernized. In March 1974, as part of efforts to streamline business management, new, high-precision machine tools reflecting the latest technology were introduced and added to the machine tool division of the main factory. In addition, Mabuchi Precision Industries, Ltd. was established in Tatebayashi City, Gunma Prefecture for in-house production of motor shafts. An airplane motor went on the market in July as a new power source for model airplanes. In March 1975, a motor with a built-in electronic governor went on the market, allowing the company to move into new markets for cassette tape recorders, home stereo equipment and other household electronics. The RF-510G was born. It sold for 400 yen, the same price as an outdated mechanical governor. At first, electronics companies were somewhat leery of working with a supplier that got its start making motors for toy cars. But one after another, brand name manufacturers chose the quality and price of the RF-510G, and the Mabuchi brothers helped bring affordable Japanese radio cassette decks, portable headphone stereo CD players, and numerous other products in the audio visual field, to consumers across the world. By being first to market with a completed product while rival motor manufacturers were still at the prototype stage, Mabuchi Motor built considerable goodwill in the consumer electronics industry. Then, in May, nickel-cadmium batteries were introduced onto the market, and Mabuchi responded by producing a fast-action battery charger for home use as a low-energy electric power source. By July, the sales department moved to the headquarters at Matsudo, and a comprehensive administration system encompassing production, sales, technology and financial operations was established. In September 1975, a geared motor went on the market, allowing Mabuchi to enter the vending machine market and other markets. Also that month, car mirror motors came on the scene, and the company fully entered into the automobile electrical equipment market. In order to increase competitiveness in a fluctuating world economy, and to expand productive capacity, in July 1976, a new production facility was constructed in Tsuen Wan by Mabuchi Industry Co., Ltd. of Hong Kong. Then, in August, a new power system went on the market for electrically powered radio-controlled models by combining a high-powered motor and nickel-cadmium battery that can be quickly recharged. The New York representative office was closed in January 1977 and, instead, Mabuchi Motor America Corp. was established in New York City for sales and service operations to respond directly to local needs and to focus on developing new markets (in 1997, the US head office was moved to Detroit).
