Controil, controlled by Fras-le, one of Randon's companies, adapted its plastic injection process for the production of the plastic front support of the masks and the elastics used in the fitting of protectors. Located in São Leopoldo (RS) and operating with hydraulic brake systems and polymers, the unit is the only one in the group with the necessary technology to produce plastic and rubber parts. Recyclable materials are being used to manufacture both the front support and the elastic of the masks. The adaptation of Controil's manufacturing line was a partnership with IMER, a company from Porto Alegre (RS) that built free of charge the tool that allows the manufacture of parts for the mask.

The front support and the elastic produced by Controil are delivered to other partner companies of the project, which assemble the facial protection masks with voluntary support from the Armed Forces. The finished products, a total of 190,000 pieces, are being donated to hospital institutions and to the Civil Defense of the State of Rio Grande do Sul.
