History

1960s

May 1961Founder Yoshimasa Mozawa established Kanto Seiki Co., Ltd. in Eda-cho, Maebashi City, Gunma Prefecture (currently “Eda Factory”) with a capital of 5 million yen.
Started production of “steering gear cases” for automobiles.
July 1963Capital increased to 9.8 million yen.
August 1964Expanded the factory in response to an increase in orders for “steering gear cases.” Around this time, in-house experiments on the thermal displacement of machine tools finished analyzing the effects of changes in oil temperature on machine tools.
April 1965The product name of “Oil temperature automatic adjuster” is named “Oilmatic”. Started production and sales as OCH type.
November 1968Capital increased to 19.8 million yen.

1970s

April 1970Due to an increase in orders for Oilmatic, a new “Otomo Factory” (current head office factory) was constructed in Otomo-cho (currently Owatari-cho), Maebashi City, Gunma Prefecture. Started operation as a specialized factory for oilmatic and cooling equipment.
December 1970Capital increased to 29.4 million yen.
1971Developed and started sales of refrigerated dehumidifier “Airmatic”.
April 1973Concluded a sole agency agreement for Oilmatic in Europe with Übersehandel (UHAG: Zurich, Switzerland), and started exporting to Europe.
Three utility model patents related to Oilmatic are granted.
Formed a business alliance with Tohatsu Co., Ltd. and started manufacturing small refrigeration equipment for cold chain vehicles.
July 1974Capital increased to 33.22 million yen.
Completed and started sales of “Crease”, a local cold air device (spot cooler) for factories.
19764 patents related to Oilmatic are granted.
The Machinery Division was made independent, and the number of machine tools and engineers was increased. As a result, the company will be ready to deal with increased orders for specialized machines, automatic assembly machines, and precision jigs.
August 1977Capital increased to 40 million yen.

May 1982Developed and started sales of mold automatic temperature controller “Moldmatic” series.
July 1982Capital increased to 48.4 million yen.
October 1982Developed a high-precision oil temperature control device in preparation for “higher precision machine tools,” which is expected to progress in the future.
Developed new products such as “Pick & Place”, “Cartesian coordinate system robot”, and “NC control box packing machine” in the Machinery Division.
Entered the field of industrial robots with the “Pickmatic” auto handling system.
April 1983Capital increased to 85 million yen. Obtained capital participation from Tokyo Small and Medium Business Investment & Consultation Co., Ltd.
Designated as a model factory for streamlining small and medium enterprises in Gunma Prefecture.
July 1986Established the Product Development Office.
October 1986Completed FA system module “Tray Changer” series and started sales.

  • 1981 Moved the head office to the “Otomo Factory” and became the “Main Factory”.

1990s

July 1990Capital increased to 93.5 million yen.
May 1991Added a new machine tool factory in the Eda Factory.
As a result, an integrated production system will be established for the Chiller Division and Machinery Division.
March 1992Established a new multi-level automated warehouse in the head office factory.
April 1992Designated as a small and medium enterprise streamlining model factory by the Small and Medium Enterprise Agency.
August 1992Expanded the headquarters office building in the headquarters factory.
1998In order to respond to the high-speed and high-precision spindles of machining centers, we have developed and obtained a patent for the inverter control oilmatic, which is the first in the industry.
Started model development as MRSC(D) series.
