Constant research and development of new technologies have allowed Main Group Technologies to satisfy rigid qualitative standards required by safety regulations, while at the same time replying to the needs of the market for comfortable and fashionable products.

There are four families of materials (thermoplastics, EVA, rubber, and polyurethane – used on their own or in combination with one another) developed by Main Group Technologies, which the company has used to design and construct diversified production systems in accordance with specific needs.

This is the case of Pragma, the new modular system that is flexible and user-friendly for the production of soles directly injected onto uppers in combined matmain-group-star_prodotto_liv_moderials (rubber, TPU, and compact PU for the outsole and Expanded Polyurethane for the midsole). With powerful mould-holder clamping, a high-performance final product is guaranteed. There is also the Omega 909, the automatic rotary machine for the injection of single-, two- or multi-density boots in Polyurethane and Combined Materials (TPU for the outsole, PUR for the bootleg), which is also the only machine performing TPU+PUR injection in one integrated cycle on the same machine, thanks to an efficient and innovative moulding system.

For rubber, instead, Pegasus represents the most innovative automatic rotary machine for injecting-pouring outsole inserts in rubber. The system allows for a drastic reduction of vulcanization times, which results in an increased production rate and important energy savings. The Star system, instead, is ideal for moulding vulcanized rubber, thanks to the extra-powerful mould-holder with totally hydraulic clamping, which guarantees precision in the reproduction of the details of the mould drawing.
