More than half a century ago, the HK type series heralded a new era – high-pressure polyurethane processing. Today, high-pressure metering machines form the basis when it comes to processing a whole variety of PU applications. Depending on the plant configuration and the mixhead used, modern metering machines allow all kinds of rigid and flexible foams as well as integral skin foams to be produced. The consistently modular construction offers processors more flexibility, also in the long term, if, for example, they later wish to expand production or combine with production plants.
