The war was over and Francisco Martins was a man much involved qith the Pyritechnics Industry. He became a pioneer of the fuses manufactoring in Portugal.
He built his own machinery himself and started to produce the first fuses. His children followed his steps.
The quality became famous and in 1952 he stopped his activity in pyrotechnics to dedicate himself exclusively to the manufacture of fuses.
In the same year, he appointed his son, Jacinto C. Martins, who assuming complete management in 1964, improved the process of manufacture by applying modern technology to the manufacture of the SM fuses.
