IKA high performance HKD and HKS horizontal kneading machines are twin-bowl kneading machines with horizontally arranged kneading blades, able to process mixtures with very high viscosities. The distinctive feature of these kneading machines lies in their kneading elements, which enable them to be adapted to a broad spectrum of applications: from the production of low viscosity adhesives (hot melts) to extremely high viscosity rubber mixtures.
