- History of Establishment
The SPE Japan Section was established in the 1950s, during the infancy of Japan’s plastics industry, driven by the strong enthusiasm of engineers seeking to acquire the latest technological information from the United States. The details of its history are summarized below.
1.1 Background of Establishment
In the 1950s, Japanese engineers were extremely eager to obtain overseas plastics technology information, particularly from the United States. At that time, SPE Journal (currently Plastics Engineering), published by the Society of Plastics Engineers (SPE)—an organization of plastics engineers across the United States—served as an invaluable reference. Japanese engineers held a strong desire to subscribe to it officially.
1.2 Catalyst for Establishment
The direct trigger for the section’s establishment was the visit to Japan by Mr. Huggins, an executive at The Dow Chemical Company.
Mr. Tamotsu Ikeda (Nichimen Corporation), a prominent member of the “Plastics Technology Research Group” at the time (now the Japan Society of Plastics Technology), introduced Mr. Huggins. Invited to a regular meeting at the Osaka Municipal Technical Research Institute, Mr. Huggins spoke about SPE’s active operations. On that occasion, he suggested, “Japanese engineers can also join if they have a proven track record. Why not establish a Japan Section?”
1.3 Launch of the SPE Osaka Section
Mr. Tadao Nakao (Nippon Kako Zai, currently Sumitomo Bakelite), who was then president of the Research Group, agreed with this proposal, and discussions progressed rapidly.
Establishment Date: Early summer of 1956
Name: Initially named the “SPE Osaka Section” because its initial membership was centered in the Osaka area.
Initial Officers:
President: Keiji Oshima (Director, Osaka Municipal Technical Research Institute)
Councilor: Tadao Nakao
Secretary: Kiyotsugu Nakayama (Chief of Secretariat, Kansai Branch of the Japan Synthetic Resin Industry Association)
1.4 Rename to the Japan Section
Following its inauguration, membership steadily increased, with members in the Tokyo vicinity coming to account for nearly half of the total. To reflect a broader organizational scope, the group was renamed the “Japan Section (SPE Japan Section)” in 1963.
- Hosting of RETEC
RETEC (Regional Technical Conference) is t he designation for regional technical conferences organized by individual sections of the Society of Plastics Engineers (SPE). Within the SPE Japan Section, RETEC has evolved into a cornerstone activity, serving as a vital international forum for technical exchange. Its history is detailed below.
