A leader in its sector, GSM was founded in Carpi in the early ‘90s by Giuliano Rossi and his sons Massimiliano and Stefano, who doggedly wanted to specialise in the manufacture of automatic machines for the application of hot fix rhinestone, crystals and cabochons. Our goal was to cater to the market demand for distribution of crystals to be used in the creation of fashion garments and accessories. Thanks to our dedication, seeking perfection and innovation, the GSM crystals and strass are now used in various sectors from clothing, shoes,fashion accessories to jewellery and furnishing. Chosen by big names in the fashion system because of their superb quality, these perfect crystals adorn exquisite objects of desire all over the world. GSM offers the best in system design and construction for the sector industries.


Continuously developing technology, curiosity and acuteness characterise the work of GSM, which debuted in 1996 with the world preview of Fixy 2400 Twin Head: the first automatic machine with dual loader for the application of hot fix rhinestones. Since then the GSM innovation process has not stopped resulting in the design of Fixy 2400 Twin Head Ultrasonic: the machine with all the features of the earlier model and in addition an exclusive ultrasonic soldering system. The last-born of the family is Fixy Automatic capable of producing any pattern directly on the support, fabric or leather, without using preconfigured guides.
