SIMA was founded in 1943 by two young men grown and trained in the Irish textile area: Alberto Mazzoni and Gino Serra.
In its beginning SIMA manufactured ancillary machines for spinning and twisting such as winders and other finishing machines like balling machines and small twisters.
Later on,  SIMA specialized themselves in the manufacturing of Machinery for ropes and twisted yarns,  becoming a leader in this field, strengthening SIMA presence all over the the world.
More than 10.000 SIMA machine are running in every continent, from North and South America, to Europe, Africa, Asia and Oceania.

Early in the 1970s, SIMA realized that the future would have demanded a quick technological innovation and therefore  considerably strengthened its  research and development depts. The result was a launch onto the market of a series of models of rope layers and twisters absolutely revolutionary which traced a new path in the field of twine and rope making machinery.

At the end of the '70s, the importance of supplying turn-key projects to costumers became evident to SIMA headquarters, including lines for yarn manufacturing, completing its production upstream of the twisting and rope making phase.
Aiming at not taking away technical resources from its widely accepted line of products, this development was carried out through the introduction of a new division, called PROMATECH, specialized in the manufacturing of complete extrusion lines for processing plastic material and drawn fibres in particular .

For more then three decades SIMA has been manufacturing a very wide range of extrusion lines.
The innovation and research approach of this new division was immediately recognised not only by the market, but also by the Italian Government, and in fact in 1988, PROMATECH, division of SIMA, was included by Italian Government  in the list of the lab industry, certifying the character of innovation of this company.

Due to the production increase and the introduction of new technologies a radical reorganization and further strengthening of SIMA was then necessary,  with subsequent move to the very modern factory in Crespellano, near Bologna, spread on a surface of 40.000 square metres, 20.000 of which assigned to production departments and 3.000 to office and services, and where more than 100 people are working.

Today, SIMA is able to offer to customers a complete know-how, from pellet processing to packing of finished product, availing itself also of the most modern systems of computer aided design (CAD).

SIMA manufacturing product range include a very wide range of equipments manufacturing products for the packaging industries like strap, yarn, mono or multifilament, for the textile industries like mono and multifilament or tapes, and for the production of artificial grass, either monofilament or fibrillated tapes.
