MACASA was established in 1964 in Santa Ana, El Salvador. It was founded by Gebr. Weyersberg - a German toolmaker whose origin dates back to 1787 when it began manufacturing swords, knives, and bayonets in the famous blade-making city of Solingen. Joining in Gebr. Weyersberg's expansion into Central America as business development and investment partners were the Deutsche Entwicklungsgesllschaft (DEG) of Germany, Adela Investments Company from Luxemburg, and a group of Central American investors - mainly Salvadorians.
