Overview
Kinyosha Co., Ltd. (株式会社金陽社), often branded as KINYO, is a Japanese manufacturer of rubber rolls and rubber blankets used in printing and a wide range of industrial applications. The company traces its origins to November 1924, when Kinyosha Kogyosho (合資会社金陽社工業所) was founded in Tokyo's Kyobashi district to manufacture glue rolls for printing. In 1930 it developed oil-resistant rubber rolls for newspaper rotary presses and reorganized as Kinyosha Co., Ltd. (株式会社金陽社), with Kaisuke Yamamoto as its first president. That same year it shifted entirely from glue rolls to rubber roll production. In 1933 it completed rubber blankets for newspaper rotary and general printing, establishing the foundation of its core business. Over the following decades Kinyosha expanded its product range and manufacturing footprint. It opened a Kyoto plant in 1949, an Osaka branch in 1950, and added specialized factories for papermaking and general industrial rubber rolls in 1952. It developed solvent-resistant KP Rubber in 1958, commercialized polyurethane rubber Euron S in 1959, and developed fluororubber products under the Perflon name in 1960. Subsequent innovations included the compressible offset printing blanket Air Excel S5000 in 1967, high-precision rubber sheet Goldpren in 1971, room-temperature-curing fluororubber paint Perflon Paint in 1972, and the highly compressible blanket S7000 in 1980. The company also developed the synthetic granite roll Unirock in 1981. Kinyosha has pursued internationalization since the late 1970s. In 1979 it licensed manufacturing technology for copier rubber rolls to Felix Bottcher, described as Europe's largest rubber roll manufacturer, headquartered in Cologne, Germany. In 1987 it established a joint venture with that company, and in 1988 it set up a local subsidiary in the United States. The company states that it has been the largest domestic manufacturer of rubber rolls and rubber blankets in Japan for around 90 years. Today Kinyosha organizes its business into printing, industrial-related products, OA-related fields, and high-function fields. Its printing products include blankets and rolls for offset printing, rolls for gravure printing, and rolls for various other printing methods. Its industrial products serve film, papermaking, steel, and other industries, while its OA products include rubber rolls for copiers, multifunction printers, and printers. The company maintains ISO 9001 and ISO 14001 certification at all domestic sites and describes its products as supporting everyday life in unseen but familiar ways. It is headquartered in Shinagawa, Tokyo, and operates through domestic sales offices and overseas group companies.
History
Kinyosha Co., Ltd. began in November 1924 as Kinyosha Kogyosho (合資会社金陽社工業所), a limited partnership founded in Tokyo's Kyobashi district to manufacture glue rolls for printing. In May 1930 the company developed oil-resistant rubber rolls for newspaper rotary presses, and in December 1930 it reorganized as a joint-stock company, Kinyosha Co., Ltd. (株式会社金陽社), with capital of 150,000 yen and Kaisuke Yamamoto as its first president. Its head office was established in Ikebukuro, and the company shifted entirely from glue rolls to rubber roll manufacturing. In October 1932 the head office moved to Osaki in Shinagawa Ward. In 1933 the company completed rubber blankets for newspaper rotary and general printing, a product line that would become central to its business. The postwar period brought rapid expansion. In October 1944 Yoichiro Nakamura became the second president. In November 1949 Yuzo Kimura became the third president, and in December 1949 the Kyoto plant was opened. An Osaka branch followed in April 1950. In April 1952 the company added specialized factories at its head office for papermaking rubber rolls and general industrial rubber rolls. In 1958 it developed KP Rubber, a solvent-resistant rubber resistant to benzene and trichlene. In 1959 it commercialized Euron S polyurethane rubber, and in 1960 it developed Perflon fluororubber products. In September 1960 it opened a Sapporo office to serve Hokkaido, and in April 1961 a Nagoya office to serve the Chukyo region. In November 1962 capital was increased to 50 million yen. In November 1963 Koichiro Shima became the fourth president. Product innovation continued through the 1960s and 1970s. In December 1967 the company developed Air Excel S5000, a compressible blanket for offset printing. In August 1968 it opened a Fukuoka office for the Kyushu region. In March 1971 President Shima received the Medal with Blue Ribbon. In November 1971 the company developed Goldpren, a high-precision rubber sheet, which later evolved into Kinyo Board, a cushioning material for hot presses. In April 1972 it developed Perflon Paint, a room-temperature-curing fluororubber paint whose applications later expanded to include metal gaskets for passenger car engines. In May 1972 Yutaro Nakamura became representative director and chairman. In October 1972 the company received the Minister of Labour Award as an excellent company in labor health management. In April 1973 it opened a Hiroshima office for the Chugoku and Shikoku regions. In June 1974 the Takehara plant was built, and in September 1975 the Minori plant was built. Internationalization accelerated from the late 1970s. In March 1979 the company licensed manufacturing technology for copier rubber rolls to Felix Bottcher, described as Europe's largest rubber roll manufacturer, headquartered in Cologne, Germany. That same year it developed Bon Stamp. In December 1980 it developed the highly compressible blanket S7000 and the papermaking urethane rubber roll Euron H (NK method). In February 1981 it developed Unirock, a synthetic granite roll. In April 1981 it opened a Nagoya research facility. In 1987 it established a joint venture with Felix Bottcher, and in 1988 it set up a local subsidiary in the United States. Kinyosha states that for around 90 years it has been the largest domestic manufacturer of rubber rolls and rubber blankets in Japan, and that it has expanded into general industrial rolls and OA equipment rolls in response to changing times. The company maintains ISO 9001 and ISO 14001 certification at all domestic sites and continues to develop products for printing, industrial, OA, and high-function applications.
