    for polyurethane, for S-RIM, for solid fillers


Cannon InterWet is a high pressure mixing head. It has been designed for co-injection of filled and reinforced polyurethane. The mixing head is suitable for the use within co-injection technological processes and the feeding of a variety of solid fillers.

In the InterWet FPL 18 for example, the solid component is metered and fed from the upper section of the head via mechanical controls. The feeding is helped by a high-intensity, compressed air flow. The inflow of the liquid blend from the mixing chamber leads then to a synchronization between filler and liquid part resulting in an optimal and precise pouring action.

After the solid component and the liquid are mixed together, the combination is co-injected into the mould. A key feature of this solution is that the blending takes place within the mixing head right in front of the mixing chamber. This is the same zone where the mixture is directed by the turbulent flow towards the nose via a 90 degrees flow deviation. This process is implemented in order to make use of the kinetic energy of the pressurized liquids to completely and efficiently wet the solid part of the stream.
