Cosma began in 1980 building specialty machines on behalf of third parties. It began with the building of machines for wood manufacturing and for the domestic lighting sector.
In 1983 Cosma began a special cooperation with a private factory for the manufacturing of refrigerator foaming plants.
This cooperation caused Cosma to expand and consequently to build two additional factories, Mecos and Astom. Astom specializes in the manufacturing of refrigerator foaming plugs and has become one of the world's largest producers of this product.
In 1995 a fourth factory was built named Forest. Forest is supplied with many special machines to manufacture special mechanical parts. Forest also manufactures and assembles special conveyors for transporting refrigerators and various other parts for the refrigerator foaming plants. Cosma has an additional advantage by having its own machine shops.This allows Cosma to manufacture 90 % of all machined parts used in the production of it's plants.
