The revolutionary idea behind Rollepaal’s multilayer die heads technology is the symmetrical branching of the melt to feed the layers, guaranteeing the best possible layer distribution.
The layer distribution is independent of melt viscosity, as there is no need for a melt flow restrictor gap with different lengths around the die circumference for correction. The design features a symmetrical split of short, round channels in each disc, preventing the melt from clogging the die head.
Depending on the application and formulation, the RMD die head is provided with either single or double compression tooling. The die head, with modular design, includes Smart Tool Change and Smart Centring. The easily accessible, short, round distribution channels make cleaning, when necessary, an easy task.
The RMD die heads have a perfect skin distribution to maximize material savings. Rollepaal’s die heads allow to save up to 70% virgin material. They are unique because the melt is transported through completely symmetrical round channels. These die heads enable quick tool change.
Next to these benefits, the RMD die heads also have a modular set up and are designed with round branches for quick and easy cleaning. They are suitable for foam core and solid wall. The die heads have a process range from K57 to K67 and foaming with 100% recycled (post-consumer scrap) material.
