Leo Tanaka Moldmaker

LST Moldmaker Inc. is an injection moulding manufacturer in California, United States. The business was founded in 1970 as Leo Tanaka Moldmaker, Inc. and in June 2013 it was renamed LST Moldmaker Inc. The company is now run by Leo Tanaka’s son, Alan Leo Tanaka.

Leo Tanaka Moldmaker provided keycaps to Datanetics amongst other brands. Their market position was more a specialist provider of more custom parts, than large volume standard types.

LST Moldmaker confirmed that the tooling for Datanetics keycaps is still in existence.

A Twitter post by “Foone” shows some sample keycaps from Leo Tanaka Moldmaker, with some kind of note dated to 21st October 1976.
