To diversify the activities of the Colombo family, which until then had focused exclusively on manufacturing peanut and bean harvesting machines, in 1982 the AEMCO (Electric and Mechanic Apparatus Colombo) factory for welding was created.

After a year in this activity, the vision of its entrepreneurs identified the emergence of a strong demand for agricultural cardans and, from then on, with the philosophy of meeting all the needs and specifications of its customers, AEMCO ended its welding activity and definitively started supplying cardans for the agricultural machinery industry and spare parts for retail.

Continuing with its strategy of consistent and diversified growth, in 1984 the company COTRAME – Colombo Metal Transformations – was founded, initially aiming only at meeting the needs of supplying crossheads for AEMCO.
