IMACASA was established on March 12, 1964 in Santa Ana, El Salvador. Gebr Weyersberg, the Deutsche Entwicklungsgesllschaft (DEG) of the Federal Republic of Germany, Adela Investments of Luxembourg, and an important group of local investors were among the founding shareholders.

In 1987, there was a change in equity that transformed the organic structure of the company and allowed the administration to design new policies and strategies.

From there, distribution centers were established in Central America: Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, and Panama. Trade routes were also established to serve the rest of the world.

In 2004, IMACASA developed a premium line of tools and knives for the North America and European sporting goods market.
