Industry 4.0: digitization of Zollern & Comandita's manufacturing process is being implemented by INEGI

05 November 2020

Implement digitalization to improve the monitoring of the manufacturing process, using sensors, instrumentation and even thermography, in line with the assumptions imposed by the 4th industrial revolution. This is the new challenge that INEGI is answering with Zollern & Comandita Portugal, a precision foundry company that produces turbine blades, used in car turbochargers.

"There is a growing need to increase the ability to control and view the phenomena that occurs in the process of atmospheric fusion, particularly to observe the most complex phases. Only then is it possible to continue to reduce defects and scrapproduced”, explains Bernardo Valente, responsible for the project at Zollern & Comandita Portugal.

To meet the needs identified by the company, INEGI is developing an automatic system formonitoring, in real time, the manufacturing process of lost wax casting using a thermographic camera, as well as the processing and analysis of captured images during the casting phase of ceramic moldings.

The use of thermography makes it possible to obtain and treat concrete and fundamental data on the temperatures of the materials used in this phase, contributing to the improvement of the process.

"The collection of data, the anti-error systems and the increase in the perception of the phenomena of the fusion process, which by nature is difficult control, will certainly be an enormous contributions for the change of practices, reduction of the variability of the process and reduction of scrap rates”, stresses the person responsible for the project at Zollern & Comandita Portugal.

This work is being developed within the MAGIC_4.0 project, a joint venture between Zollern & Comandita Portugal and INEGI. The project, co-financed under the Compete 2020, Portugal 2020 and European Regional Development Fund (ERDF) programs, concerns the development of a method of grain tuning by rotating electromagnetic currents, and the creation and introduction of 4.0 industry technologies in the process of lost wax casting.
