1. Technical Area (Engineering /Inspection) Developed by Marcos Dropa

2. Our purpose is to give technical support to the productive sectors, providing information for the production areas, doing so that the product will always conform to the technical demands of the client. In addition to this support our mission is to also understand the development of new technology, changing work processes and systems, aiming at the improvement of quality and the reduction of costs.
