Equipment and Technology

Industrial Metalmecánica S.A., due to its production characteristics, is one of the most important metallurgical companies serving large industrial plants throughout Argentina. Its long-standing success in both national and international markets is the result of strict quality policies developed under the framework of the ISO 9001 international standard, defined decades ago by its current board of directors.

The company’s distinctive feature is the integration of multiple production processes to execute complex metal-mechanical projects. This means that, in addition to manufacturing spare parts for different industrial plant equipment through foundry and precision machining processes, the company also designs many critical components and special parts, while performing comprehensive maintenance of machines used in most heavy industries such as thermoelectric plants, hydroelectric plants, oil refineries, petrochemical plants, compressor stations, steel mills, mining, cement, paper mills, and sugar mills, among others. In this way, it provides diverse solutions to the daily needs of major clients.

Our industrial facilities cover more than 10,000 m² of indoor space, plus another 5,000 m² of yards and warehouses. They are equipped with machines and tools whose capacities and operating power meet the demands of the market in which Industrial Metalmecánica S.A. competes. These manufacturing systems process parts with great precision. Their diverse types and models ensure safety and accuracy in all machining possibilities. This infrastructure comprises more than 100 production units, forming a solid foundation for the development of high-quality industrial activities.

At Industrial Metalmecánica S.A., decisions are made collectively. Creativity and inventiveness come into play when managers and members of the Engineering Department provide daily solutions to ongoing challenges. Our Engineering Office is dedicated to analyzing client requirements and technical documentation for their projects, in order to develop with greater precision the engineering and manufacturing processes their products demand.

Designs are computer-assisted, using current software that enhances our engineers’ capabilities and experience in these complex areas of comprehensive metal-mechanical production. All calculations and proposed results for different projects are always carried out in accordance with international standards such as ISO, DIN, ASME, AGMA, ANSI, API, ASTM, and IRAM (Argentina).

Our foundry section is a fundamental part of the company. It is the area where spare parts for industrial machines of various shapes and sizes are manufactured for use in various applications. It can cast up to 10 tons of steel and 18 tons of grey cast iron.

The foundry section is divided into three internal sectors: the first sector is dedicated to building the models to be cast, the second sector carries out the molding processes based on computer simulation verifications of pouring and the third sector, equipped with metallographic laboratories, conducts material research for the parts to be developed and performs all quality controls at each stage of the process. Each of these sectors operates with proper coordination and internal procedures for each specific project. The foundry produces castings in accordance with the materials requested by each client.

Its extensive infrastructure includes electric, cupola, annealing, and bronze-casting furnaces. Materials cast in these facilities include carbon steels, alloy steels, stainless steels, manganese steels, gray cast iron, white cast iron, ductile iron, bronzes, and more.
