Who we are



In 1965, ASTECO S.A., Association Technical Industrial and Commercial S.A., distributor of Swedish steels in Medellin finds itself in need of importing a furnace for quenching of steel in cyanide salts and a tempering furnace, with which the supply of heat treatment services starts.
Between 1968 and 1976, new and diverse equipment is acquired due to the acceptance of the heat treatments and the growing demand on its services. In 1976 the first major expansion of the plant is programmed, acquiring a space of 700 m2 to install a complete line of furnaces from Spain for heat treatment in controlled atmosphere.

By 1983, the company acquires a market position requiring the plant to operate 24 hours per day, seven days a week; a time at which it is decided to form an independent company dedicated exclusively to the heat treatment activities:


In 1985, Tratar decides to venture manufacturing of cutting blades, mainly for the paper and cardboard industries, achieving great success in the sales of these tools.

After this transformation, the services of the company acquires an accelerated growth demanding new expansions of the facilities and improved and specialized equipment. For this reason, in 1989, the plant in Medellin is expanded and a new plant is constructed in the city of Bogotá, both being catalogued as the most modern in Latin America.

In 2004, the plant in Bogotá begins offering galvanic treatments, and the same year this plant receives the national award for the technological business innovation from the ministry of industrial commerce and tourism. In 2009, Tratar starts operations in Lima, Peru, with a new heat treatment plant completely designed and manufactured in Colombia, solving thereby many deficiencies in the heat treatment services to which Peru previously was submitted.

In 2010, Tratar starts to provide plasma nitriding services through an equipment completely designed and manufactured in Colombia, developed with the support of Colciencias (Administrative Department of Science, Technology, and Innovation of Colombia), who in this project witnessed great business innovation.

In 2012, the company ION HEAT is founded with headquarters in Rionegro, Antioquia. ION HEAT is dedicated to the design and manufacturing of high technological equipment for thermal processing, its first product being plasma nitriding systems currently offered worldwide.
