PU machine manufacturers are working in several directions to increasingly improve molding processes for a compound that offers so many advantages over traditional thermoplastics. One trend is the use of polyurethanes with increasingly lower densities to reduce component weight and gain share in applications that require lighter soles.

Efforts are being made to achieve maximum precision in the manufacturing process to avoid waste and make quality control easier and faster. One of the traditional themes is to reduce air bubbles by acting on distribution systems and mold support.

Another trend is to find application solutions to prevent yellowing of white-colored polyurethanes by applying in-mold coatings and using TPU films.
