MHR Tri-Tilt Impingement
Mix Heads – For non-abrassive and abrasive applications

Category:

Product Description

MHR’s Tri-Tilt Mix Head provides an improved chemical mixing action for the Polyurethane/Foam industry. Development of the Tri-Tilt Mix Head was done utilizing Computational Fluid Dynamics Technology. The computerized simulation of material flow through the orifices at high pressure and various tilted positions has allowed MHR’s Tri-Tilt Mix Head to achieve nearly perfect mix in the mix chamber and as the material flows from nose nozzle into the mold. It was determined that these superior mix results could be accomplished through non-linear and non-coplanar impingement occurring along 3 independent axises.

The net result for the molding operation that uses MHR’s Tri-Tilt Impingement Mix Heads is a highly improved, consistent, well-mixed laminar flow output with a consistent cellular structure throughout the finished product.

MHR’s customers find significant improvement in their difficult-to-mold parts; we expect the same for your operation.
