STEMMA SRL, Polyurethane machines for the production of shoes soles
Polyurethane boots are gaining more and more shares in the “safety” and “outdoor” market. They are lighter and more comfortable than PVC boots, cheaper than rubber ones and more versatile than EVA products.
Although the traditional injection technology is the most widespread one worldwide for polyurethane boots’ production, this process level is not the most performing one, mostly in terms of productivity.
Thanks to the “RPU Spray Technology” and a revolutionary mold holder system, STEMMA has developed an innovative process, now available in the new “SIGNUM 20” polyurethane boot machine, which has allowed to overcome these limits starting a real revolution in this market.
With an effective cycle time of less than 30 seconds, which is not bound to the use of polyurethanes with long extraction times, it guarantees a higher productivity of about 30% compared to the traditional process. Furthermore, thanks to an open mold processing, it allows to create extremely light products with very thin thickness, representing an effective innovation in terms of production and characteristics of the boots.
Uniformity in the distribution of color and the possibility of using a wide range of covers represent some more characterizing aspects of this new proposal that is now available on the market.
